Key 7, DISP key 8, jog 15, input key section 4
2, SHIFT key 43 and CH. A SET key 44 and the like are provided. Here, the function key unit 4
Has keys 4a to 4e to which various functions are automatically assigned according to the operation state of the apparatus. The cursor movement key unit 5 is provided with a cursor 20 (FIG. 7) displayed on the display unit 3.
Keys 5a to 5d for moving the reference 5) up, down, left and right. The CH key 6 has a function of displaying an operation condition setting screen for setting operation conditions on the display unit 3. The SYSTEM key 7 functions as a display screen switching key for sequentially switching and displaying a plurality of types of operation condition setting screens to be displayed on the display unit 3. DISP key 8
Functions as a display screen switching key for switching the display screen of the display unit 3 from the operation condition setting screen to the waveform display screen. The jog 15 functions as a dial for setting a numerical value when setting operating conditions and the like. The input key section 42 has keys 42a to 42p, and these keys 42a to 42p normally function as display range setting keys for setting the display range on the display section 3 for each channel. , SHIFT key 43 is operated as numeric input keys for designating numerals "1" to "0" and symbols "+", "-", "." And "E". . SHIFT key 43
Has a function of switching between a display range setting key function of each key 42a to 42p of the input key unit 42 and a numerical value input key function.

In the waveform recording device 40, when a power switch (not shown) is turned on, a waveform display screen 51 is displayed on the display unit 3 as an initial screen. At this time, by inputting recording target signals from channels 1 to 4 (hereinafter, the channel is also referred to as “ch”) via a measurement probe (not shown), a waveform display screen 51 is displayed on the waveform display screen 51 in FIG. As shown, signal waveforms W1 to W4 respectively corresponding to the respective channels
Is displayed. In this case, for example, the display scale 1di when the signal waveform W3 corresponding to ch3 is displayed on the display unit 3
To change the display range, which is the voltage level per v, first, the user operates the CH key 6 to set a display condition setting screen for setting the display condition of the device for each channel as shown in FIG. 52 is displayed on the display unit 3. At this time, as shown in FIG.
It is displayed in the “range” part for ch1. A range up function and a range down function are assigned to the keys 4a and 4b of the function key section 4, respectively, and arrow displays 25a and 25b indicating the assigned functions are respectively provided corresponding to the keys 4a and 4b. It is displayed on the display unit 3.

Next, the key 5b of the cursor movement key section 5
Is operated twice to move the cursor 20 to the display region of the range for ch3. Next, the range for ch3 is changed by operating the keys 4a and 4b of the function key unit 4 to raise or lower the value by a predetermined step value. It is also possible to change the range of ch3 by operating the key 42e or 42f corresponding to ch3 to change the range of ch3, and rotate the jog 15 with the cursor 20 moved to the display area of the range for ch3. The range can also be changed by operating.

When setting the display range, the keys 4a and 4b of the function key unit 4 and the jog 15
By changing the keys 42a to 42n of the input key section 42 to numerical value input key functions instead of the numerical value up / down by the key, a target numerical value can be directly input using the keys 42a to 42n. Specifically, by operating each key of the cursor movement key unit 5, the cursor 20 is moved to a display position where a numerical value should be input. Then, SH
By operating the IFT key 43, the input key section 42
Are changed to numerical value input key functions. At this time, the keys 42a to 42n have numerical values "0" to "9" and symbols "+", "-", "."

[0007] Further, display conditions can be set while the waveform display screen 51 is displayed on the display section 3. Specifically, while the waveform display screen 51 is displayed on the display unit 3 as shown in FIG. SET
When the key 44 is operated, a screen 51 for displaying a waveform and a screen 52 for setting a display condition are superimposed and displayed on the display unit 3 as shown in FIG. Therefore, the measurer checks the signal waveform W3 on the waveform display screen 51 while checking the ch3.
Can be set.

[0008]

However, the waveform recording device 40 already developed by the applicant has the following points to be improved. First, in the waveform recording device 40, each c
When setting or changing the operating conditions such as the display range for h, as described above, the cursor movement key unit 5
After the cursor 20 is moved to the target channel using the keys 5a to 5d, display conditions are set. However, in this method, in order to move the cursor 20 to the target channel position, it is necessary to operate each of the keys 5a to 5d of the cursor movement key unit 5 many times. For this reason, this method has a problem that when a large number of signal input channels are provided, the key operation of the cursor movement key unit 5 is complicated, and it is difficult to quickly set operating conditions.

Second, in the waveform recording apparatus 40, display conditions can be set without specifying a channel by using dedicated keys 42a to 42p corresponding to a plurality of channels in advance. However, in this method, keys 42 are assigned to a plurality of channels.
Since it is necessary to correspond a to p in advance, there is no particular problem when the number of channels is small, but when a large number of signal input channels are provided, a large number of dedicated keys are provided in the operation unit 41 in correspondence with each channel. Must. Therefore, it is necessary to increase the space of the operation unit 41,
There is a problem that the device becomes large and erroneous operation may be caused.

Third, in the waveform recording apparatus 40, a waveform display screen 51 and a display condition setting screen 52 are superimposed and displayed on the display unit 3, and the signal waveform W3 on the waveform display screen 51 is confirmed. On the other hand, there is an advantage that a display condition for a target channel can be set. On the other hand, at this time, since the numerical value of the display condition setting screen 52 and the signal waveform of the waveform display screen 51 are superimposed,
There is also a problem that it is sometimes difficult to distinguish both a numerical value and a signal waveform.

Fourthly, when inputting numerical values when setting display conditions, the waveform recording device 40 uses the keys 4a and 4b of the function key unit 4 and the jog 15 to raise or lower by a predetermined step value. Therefore, there is a problem that it is difficult to quickly input a numerical value and sometimes it is difficult to set an arbitrary numerical value. When the input key unit 42 is used as an input key for numerical values, etc., it is possible to set an arbitrary numerical value quickly, but whether the input key unit 42 functions as an input key for numerical values, There is also a problem that it is difficult to intuitively understand whether the key functions as a display range setting key.

SUMMARY OF THE INVENTION The present invention has been made in view of such improvements, and has as its object to provide a measuring apparatus capable of easily, quickly and accurately setting operating conditions of the apparatus for each signal input channel. Main purpose. Another object of the present invention is to provide a measuring device that displays a measurement result in an easily viewable manner when setting operating conditions.

[0013]

According to a first aspect of the present invention, there is provided a measuring apparatus, comprising: a display unit for displaying a measurement result based on measurement data of each input signal corresponding to each of a plurality of signal input channels; A measuring device configured to be capable of setting operating conditions of the device for each signal input channel, a channel specifying means for specifying a signal input channel for which an operating condition is to be set, and a signal input channel specified by the channel specifying means And a display control unit for displaying a designated channel operation condition setting screen for exclusively setting the operation condition for the display channel on the display unit.

In this measuring device, when setting the operating condition for each signal input channel, if the signal input channel is specified by the channel specifying means, the operating condition for the specified signal input channel is set exclusively. Is displayed on the display unit. Therefore, it is possible to immediately set the operating conditions for the signal input channel without operating the keys and the like many times. In particular, when a large number of signal input channels are provided, the signal input channels can be directly specified, so that the signal input channels can be specified quickly, easily, and reliably. Can be set quickly, easily, and accurately.

According to a second aspect of the present invention, in the measurement apparatus according to the first aspect, the display control unit displays the designated channel operating condition setting screen on the display unit together with the immediately preceding display screen displayed immediately before the channel designation. It is displayed.

In this measuring device, a designated channel operating condition setting screen is displayed together with the immediately preceding display screen. For this reason, the measurer can set the operating conditions while referring to the display contents of the immediately preceding display screen. In this case, the specified channel operating condition setting screen is for exclusively setting the operating condition of only the specified channel.
Operation condition setting screen 5 in waveform recording device 40 in which operation conditions for a plurality or all channels can be set
Unlike FIG. 2, a small display area is sufficient. Therefore, for example, when a measurement result such as a signal waveform is displayed on the immediately preceding display screen, it is possible to reduce an area overlapping with the displayed signal waveform.

According to a third aspect of the present invention, in the measurement apparatus according to the second aspect, the display control unit causes the display unit to display the designated channel operating condition setting screen and the immediately preceding display screen so as not to overlap each other. It is characterized by the following.

Since the designated channel operating condition setting screen can be displayed with a small area, in this measuring apparatus, the designated channel operating condition setting screen and the immediately preceding display screen are displayed on the display unit so as not to overlap each other. For this reason, when setting the operating conditions such as the display conditions while checking the measurement results such as the signal waveform and the measured value displayed on the immediately preceding display screen, the amplitude value and the like are set according to the setting contents of the operating conditions. Since the signal waveform and the measured value in which the value changes can be identified very easily, it is possible to accurately and easily set desired operating conditions.

According to a fourth aspect of the present invention, in the measuring apparatus according to the second or third aspect, the display control section displays a designated signal input screen on the immediately preceding display screen when displaying the designated channel operating condition setting screen. The measurement result corresponding to the channel and the measurement result corresponding to another signal input channel are displayed in a distinguishable manner.

In this measuring device, when the screen for setting the designated channel operating condition is displayed, the signal input c
The measurement result corresponding to h can be easily identified from the measurement results corresponding to other signal input channels. Therefore, when setting display conditions while confirming the measurement results of signal waveforms and the like, signal waveforms and the like that change according to the set contents can be easily identified, so that desired display conditions can be set more reliably and easily. It becomes possible.

According to a fifth aspect of the present invention, in the measurement apparatus according to the fourth aspect, the display control unit is configured to display the designated signal input on the immediately preceding display screen while displaying the designated channel operating condition setting screen. The measurement result corresponding to the channel is displayed in a display color different from that of the measurement result corresponding to another signal input channel.

According to a sixth aspect of the present invention, in the measurement apparatus according to the fourth aspect, the display control section performs the measurement corresponding to another signal input channel while the specified channel operating condition setting screen is displayed. The result is hidden.

As long as the measurement result of the designated signal input channel can be identified from the measurement results of the other signal input channels, any discrimination method can be adopted. Claim 5,
In the measuring device described in 6, the measurement result of the designated signal input channel is displayed in a display color different from the measurement result of the other signal input channel, or the measurement result of the other signal input channel is hidden. Therefore, the measurer inputs the designated signal input c.
The measurement result of h can be checked very easily.

According to a seventh aspect of the present invention, in the measuring apparatus of any one of the first to sixth aspects, the channel designation means includes a numeric keypad for designating a signal input channel by a numerical value. It is characterized by the following.

As a means for designating the signal input channel, a dedicated key or the like can be provided. However, a space for the key is required, resulting in an increase in the size of the apparatus. In this measuring device, the signal input channel is
Therefore, even when a large number of signal input channels are provided, there is no need to provide a large number of dedicated keys corresponding to the number of signal channels, and a configuration capable of inputting numerical values from 0 to 9 may be used. Therefore, it is possible to configure the channel designation means without increasing the size of the device.

[0026] According to an eighth aspect of the present invention, in the measurement apparatus according to the seventh aspect, the ten keys also function as numerical value input means for setting operating conditions.

In this measuring apparatus, the numeric keypad also serves as a signal input channel designating means and a numerical value input means when setting operating conditions. Therefore, by specifying a signal input channel using the numeric keypad and then inputting a numeric value using the numeric keypad, it is possible to quickly and easily set a numerical value as an operating condition.

According to a ninth aspect of the present invention, in the measuring apparatus according to the eighth aspect, the signal input channel designated by the channel designation means is displayed, and the signal input channel is set non-active when the numeric keypad functions as the numerical value input means. A channel display unit controlled for display is provided.

In this measuring device, when the signal input channel is designated, the channel display section displays the signal input channel designated by the channel designating means. For this reason, it can be easily confirmed whether or not the signal input channel has been correctly set. When the numeric keypad functions as a numerical value input unit, the channel display unit is controlled so that the signal input channel is not displayed. Therefore, it is possible to easily understand whether the numeric keypad functions as the channel designation unit or the numerical value input unit.

According to a tenth aspect of the present invention, in the measuring device according to any one of the first to ninth aspects, the display control section operates a predetermined operating means other than an operating means for setting an operating condition. The designated channel operating condition setting screen is made non-display at the time of occurrence.

In this measuring apparatus, when the operating means other than the operating means for setting the operating condition is operated while the designated channel operating condition setting screen is displayed, the setting of the operating condition is completed. The display control means controls the non-display of the designated channel operation condition setting screen. In this case, another operating means other than the means for setting the operating condition also serves as the operating means for hiding the designated channel operating condition setting screen. Therefore, it is possible to reduce parts costs.

A measuring device according to an eleventh aspect is the measuring device according to any one of the first to tenth aspects, further comprising storage means for storing a signal input channel specified immediately before by the channel specifying means, and a display control unit. Indicates the designated channel for the signal input channel stored in the storage means when the designated channel operation condition setting screen is hidden and a predetermined operation means other than the channel designation means is operated. An operating condition setting screen is displayed.

In this measuring apparatus, when operating conditions once set are reset, if a predetermined operating means other than the channel designating means is operated, the display control means causes the display control unit to display the display immediately before being stored in the storage means. A designated channel operating condition setting screen for the selected signal input channel is displayed. In this case, a desired designated channel operating condition setting screen can be immediately displayed as compared with the case where the signal input channel is specified again, so that the operating conditions can be set more quickly. At the same time, a predetermined operating means other than the channel specifying means also serves as an operating means for redisplaying the specified channel operating condition setting screen, so that the component cost can be reduced.

The printer 18 prints a waveform signal or the like corresponding to the input recording target signal SIN. Interface unit 1
Numeral 9 outputs waveform data and the like to a personal computer (not shown) via a mounted communication board, and inputs various data from the personal computer.

In the waveform recording apparatus 1, when the power switch is turned on, a waveform display screen 27 as an initial screen is displayed on the display unit 3, and the recording target signal SIN is input via a measurement probe (not shown). By doing so, the display unit 3
For example, as shown in FIG. 1, the signal waveforms W25 to 29 of the recording target signal SIN corresponding to ch25 to ch29, respectively.
Is displayed. At this time, for example, to change the display range of the channel 28, first, the user operates the CH key 6 to display a display condition setting screen 26 for setting the display condition for each channel on the display unit 3. . At this time, a display condition setting screen 26 (not shown) capable of setting the display conditions of eight channels from ch1 to ch8 is displayed, and the “range” portion of ch1 which is the first channel is displayed. The cursor 20 is automatically displayed. The keys 4a and 4b of the function key unit 4 are respectively assigned an up function and a down function of a display range, and arrow displays 25a and 2 indicating the assigned functions.
5b is displayed on the display unit 3 corresponding to each of the keys 4a and 4b.

Here, ch2 for which the display condition is set
In order to designate 8, the key "2" and the key "8" of the numeric keypad 9 are sequentially operated to display the numerical value "28" on the channel display section 12, as shown in FIG. . In this case, since the numerical value of the input channel is displayed on the channel display section 12, it can be easily confirmed whether or not the channel has been correctly input. Next, confirm key 1
By operating No. 1, “28” displayed on the channel display section 12 is determined. As a result, a display condition setting screen 26 for setting the display range and the display position of the signal waveform for channels 25 to 32 is displayed on the display unit 3 as shown in FIG.
Is automatically displayed at the position indicating the display range for ch28.

Next, when the display range for ch28 is set to, for example, "5 mV", TENKEY1
4 causes the CPU 22 to turn off the channel display on the channel display unit 12 and
A function as a numerical input key is assigned to 0. In this case, since the channel display of the channel display unit 12 is not displayed, the measurer easily recognizes whether the numeric keypad unit 9 functions as a channel designation key or a numerical value input key. Can be. Next, each key of the numerical key unit 10 and each key of the up / down key unit 13 are sequentially operated to input a numerical value. Specifically, key 1
3b, the key of "5", the key 13c, the key of "0", the keys 13d, 13a and the key of "3" are sequentially operated, and the numerical value "+5. 0E-3 "is displayed. Next, by operating the enter key 11, the input numerical value is established, and the display range of the channel 28 corresponding to the display position of the cursor 20 is displayed as “5 mV” instead of “50 mV”.

Thereafter, when the DISP key 8 is operated, C
The PU 22 switches from the display condition setting screen 26 to the signal waveform display screen 27, sets the voltage level per 1 DIV of the display scale on the vertical axis of the signal waveform display screen 27 for the signal waveform W28 to 5 mV, The signal waveform W28 is displayed so as to match the display range. In this waveform recording apparatus 1, the range value (for example, 5 mV) shown on the display condition setting screen 26 in FIG.
Multiplied by the magnification (for example, value 1) (for example, 5 mV)
Is the actual display scale per div on the vertical axis.

On the other hand, when it is desired to set display conditions while confirming the signal waveform 28, the numeric keypad 9 is used while the waveform display screen 27 is displayed on the display 3 as shown in FIG. , A channel whose display condition is desired to be set is designated. For example, when the display range for ch 28 is set from “50 mV” to “5 mV” in the same manner as in the above example, while the waveform display screen 27 is being displayed, the “2” key of the numeric keypad 9 The "8" key and the enter key 11 are operated in order. Thereby, the CPU 22
Indicates that the designated channel number is stored in the RAM 24 and, as shown in FIG. 3, the direct input screen 2 corresponding to the designated channel operating condition setting screen in the present invention.
8 is displayed on the right side of the waveform display screen 27 in the display unit 3 so as not to overlap with the waveform display screen 27 displayed immediately before. The direct input screen 28 is for setting display conditions corresponding to only the designated channel, and includes a display color displayed in the same color as the display color of the set signal waveform. Designation part 2
9 and a range value display section 3 for displaying the set range value
0 and 0 V with respect to the amplitude voltage of the signal waveform are plotted on the vertical axis of the waveform display screen 27 (the lower end is 0%, the upper end is 10
And a zero position display unit 31 indicating what percentage of the position corresponds to (0%). Therefore, by using the direct input screen 28, unlike the waveform recording device 40 in which various keys need to be operated several times before setting the display condition of each channel, the display condition of the channel 28 is immediately changed. Can be set.

When the direct input screen 28 is displayed, the CPU 22, as shown in FIG.
Screen 2 for displaying only the signal waveform W28 corresponding to
7 and signal waveforms W25 to W corresponding to the other channels.
27 and W29 are controlled not to be displayed. in this case,
While the signal waveforms corresponding to the other channels remain displayed, the signal waveform W28 of the designated channel 28 is different from the display colors of the other signal waveforms and is easily displayed (for example, other signal waveforms). May be displayed in red when the color is white). Thereby, the signal waveform of the display condition setting target channel can be easily identified. Next, the range is changed using the direct input screen 28. in this case,
By operating the key 13c of the up / down key unit 13 or the numeric key unit 10, the range value is changed from the value "50" to the value "5". In this state, as shown in FIG. 4, a signal waveform W28 obtained by enlarging the original display waveform by 10 times in the vertical axis direction is displayed on the waveform display screen 27. At this time,
Since the signal waveform W28 changes instantaneously according to the set value of the display condition, it is possible to confirm the suitability of the set value of the display condition. As a result, the display condition can be set easily and accurately.

Next, operating means for setting operating conditions in the operating section 2, for example, various keys other than the numerical key section 10, the cursor moving key section 5 and the up / down key section 13 (for example, the function key section 4) By operating the keys 4a to 4e), the direct input screen 28 is not displayed and only the previous display screen is displayed. In this case, since the channel number specified immediately before is recorded in the RAM 24, operation means other than the numeric keypad 9 as the operation means for specifying the channel, for example, any key 1 of the up-down key section 13.
When any one of 3a to 13d is operated, the CPU 22 causes the direct input screen 28 for the immediately specified channel to be displayed again. When the display color is to be changed, the display color can be set using each key of the cursor movement key unit 5, and when the zero position is to be changed, the desired color can be set using the keys 13a and 13b of the up / down key unit 13. Can be set.

As described above, according to the waveform recording apparatus 1, by using the direct input screen 28 corresponding to the channel specified by each key of the numeric keypad 9,
The display conditions for the specified channel can be set quickly and easily. Also, by using the numeric keypad 9 as a numeric input key, it is possible to input a set value very easily. In the waveform recording device 1, various setting values are input by operating the keys 4a and 4b of the function key unit 4 and the jog 15 in the same manner as the waveform recording device 40 already developed by the applicant. You can also.

The present invention is not limited to the above embodiment of the present invention. For example, in the embodiment of the present invention,
Although the direct input screen 28 is displayed on the right side of the waveform display screen 27, the display position, the setting content, and the display method can be appropriately changed. Further, in the present embodiment, the numeric keypad 9 is provided in the operation unit 2. However, the numeric keypad 9 is formed separately from the waveform recording device 1 and connected by a cable for use. You may.

Further, in the embodiment of the present invention, the channel display unit of the present invention is independent of the display unit 3, but the designated channel can be displayed on the display unit 3. However, as shown in the embodiment of the present invention, when the channel display unit 12 and the numeric key unit 10 are adjacent to each other, the display of the channel and other signal waveforms are displayed to the measurer. , Can be clearly distinguished. Further, in the embodiment of the present invention, the waveform recording device 1 has been described as an example of the measuring device according to the present invention. However, the measuring device according to the present invention may include various devices such as a voltmeter, an ammeter, and a wattmeter. Of course, it can be applied to a measuring device.
