DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement apparatus for displaying a measurement result on a measurement result display screen according to the operation conditions of the apparatus set on the operation condition setting screen.

[0002]

2. Description of the Related Art As a measuring device of this kind, the applicant has already developed a waveform recording device 51 shown in FIG. As shown in the figure, the waveform recording device 51 includes a display unit 52 capable of switching and displaying various display screens, and an operation unit 53. The operation unit 53 includes a CHAN key 4, a DISP key 5, a jog dial, 6a, shuttle dial 6b, cursor moving key unit 7, function key unit 8, and S
Various operation switches such as a TART key 9 are provided. In the waveform recording device 51, a plurality of measurement unit insertion slots (not shown) for inserting measurement units capable of performing various electrical measurements are provided on the right side of the main body. In this case, when a measurement unit according to the measurement purpose is inserted into the measurement unit insertion slot, the waveform recording device 51 assigns a channel number to the inserted measurement unit according to a predetermined rule. Therefore,
The operator sets operating conditions such as an input range and a display magnification for each of the assigned channels, so that the voltage, current, temperature, and temperature measured by the measurement unit corresponding to the channel to the waveform recording device 51 are set. Various signal waveforms such as distortion can be displayed on the display unit 52, printed by a printer (not shown), and recorded on a floppy disk.

In this waveform recording device 51, when a power switch (not shown) is turned on, a waveform display screen 61 is displayed on a display unit 52 as shown in FIG.
Signal waveforms W1a and W2a measured by the measurement units corresponding to No. 2 are displayed. At this time, when the amplitude value of the signal waveform W2a whose amplitude value is displayed slightly smaller is enlarged and displayed, the channel setting screen 62 shown in FIG. 9 is displayed by operating the CHAN key 4 of the operation unit 53. It is displayed on the unit 52. At this time, the waveform recording device 51 changes the amplitude value of the signal waveform W2a on the waveform display screen 61 by changing the set value of “range (input range)” or “magnification (display magnification)”. be able to. Specifically, for example, when changing the set value of “range”, the operator operates the waveform display screen 6.
Based on the amplitude value of the signal waveform W2a displayed in 1 and the range setting value currently set on the channel setting screen 62, the range is changed to a setting value predicted to be a desired amplitude value. . At this time, by operating the keys 7a to 7d of the cursor moving key unit 7, the CH
The cursor 60 is moved to the display area corresponding to “range” for “2” (FIG. 11 shows a state where the cursor 60 has already been moved). Next, the keys 8a and 8b of the function key section 8 and the jog dial 6a
Alternatively, by operating the shuttle dial 6b, for example, "5 m
V "is displayed.

In this state, when the key 8e of the function key section 8 is operated, the range of the channel 2 becomes "5 mV".
Is changed to Thereafter, by operating the DISP key 5, a waveform display screen 61 is displayed on the display unit 52, and further, by operating the START key 9, the waveform display screen 61 is displayed as shown by a dashed line in FIG. 10. The amplitude value of the signal waveform W2a before changing the range is 1
The signal waveform W2b enlarged to 0 times is displayed in place of the signal waveform W2a (in this case, only the signal waveforms W1a and W2b are displayed on the waveform display screen 61 shown in the figure). In this case, the signal waveform W2b is set too small as shown in FIG.
Are protruded from the waveform display screen 61.

At this time, when resetting the range to a desired amplitude value, first, the CHAN key 4 is operated to display the channel setting screen 62 on the display section 52.
Is displayed again. Next, by operating the keys 7a to 7d, the cursor 60 is moved to the display area corresponding to the "range" for CH "2". Then key 8
By operating the a, 8b, the jog dial 6a or the shuttle dial 6b, for example, "10 mV" is displayed on the display portion of the range. In this state, the key 8e
By operating, the range of channel 2 becomes “10 m
V ". Thereafter, the user operates the DISP key 5 to display the waveform display screen 61 on the display unit 52.
Operate the START key 9. As a result, the signal waveform W is displayed on the waveform display screen 61 as shown by the solid line in FIG.
A signal waveform W2c having an amplitude value 1/2 times that of the signal waveform W2b is displayed instead of the signal waveform W2b (in this case, the signal waveforms W1a and W2c are displayed on the waveform display screen 61 shown in FIG.
Only appears).

[0006]

However, the waveform recording device 51 already developed by the applicant has the following points to be improved. That is, the waveform recording device 51 can display a signal waveform with an arbitrary amplitude value by changing the set value of “range” or “magnification” displayed on the channel setting screen 62. However, in the waveform recording device 51, for example, when the range as the operating condition is changed, new setting contents are immediately displayed on the channel setting screen 62 instead of the already set contents set immediately before. Therefore, at this time, the signal waveform displayed immediately before on the waveform display screen 61 and the set value of the range currently displayed on the channel setting screen 62 are in an unrelated state. For this reason, the set value of the range predicted to be the desired amplitude value is changed to the amplitude value of the signal waveform displayed on the waveform display screen 61 and the set value of the range currently set on the channel setting screen 62. Cannot be determined with reference to the above. In this case, there is no problem if the set value of the range when the signal waveform W2a is displayed on the waveform display screen 61 is stored. However, when the set value is forgotten, the signal waveform is displayed again in the newly set range, and the range is reset based on the amplitude value of the signal waveform at that time and the set value of the range at that time. The setting must be reset, and the operation for displaying the signal waveform having the desired amplitude value is complicated and erroneous setting is likely to occur. Therefore, there is a demand for improvement.

On the other hand, the current setting value of each setting item set for each channel is printed in advance by a printer by a predetermined operation, and the range is changed and set while referring to the printed current setting value. Can. However, in such a case, even if incorrect setting can be prevented,
Each time the setting is changed, the current setting value must be printed on the recording paper, which further complicates the operation for changing the setting, and causes other problems that the recording paper is consumed more than necessary.

The present invention has been made in view of such improvements, and has as its main object to provide a measuring apparatus capable of setting operating conditions of the apparatus quickly and accurately.

[0009]

In order to achieve the above object, the measuring apparatus according to the first aspect of the present invention displays a measurement result display screen according to the operation conditions of the apparatus set on the operation condition setting screen displayed on the display unit. In a measuring device that displays measurement results,
When displaying an operating condition setting screen for a predetermined operating condition, displaying the previously set content when the measurement result was displayed immediately before according to the already set content for the predetermined operating condition on the display unit. I do.

In this measuring apparatus, for example, the set value of the range as the already set contents of the operating condition displayed on the operating condition setting screen is, for example, the signal waveform of the measurement result displayed on the measuring result display screen. The relationship always corresponds to the amplitude value. Therefore, the operator can reset the operation condition while referring to the measurement result displayed on the measurement result display screen and the already set contents displayed on the operation condition setting screen. Therefore, it is possible to set operating conditions quickly and accurately.

According to a second aspect of the present invention, in the measuring apparatus of the first aspect, a selection candidate group display screen for displaying a plurality of operation condition candidates that can be selected for a predetermined operation condition is displayed together with the operation condition setting screen. And displays the set contents on the selection candidate group display screen.

[0012] Even when the operating conditions of the apparatus are set by inputting numerical values, the set contents of the operating conditions can be displayed on the display unit. On the other hand, in this measuring device, a plurality of predetermined operation condition selection candidates are displayed in the selection candidate group display screen, and the previously set contents set immediately before are displayed on the selection candidate group display screen. Therefore, the operator can easily select a desired operation condition selection candidate from a plurality of operation condition selection candidates while referring to the set contents. For this reason, it is possible to set operating conditions quickly and accurately.

According to a third aspect of the present invention, in the measuring apparatus of the second aspect, a predetermined mark is displayed for an operating condition candidate corresponding to the set content.

Regarding the already set contents of the operating condition, the operating condition may be displayed by numerical values or characters. However, in this case, the display space increases by the space of the numerical value or the character. On the other hand, in this measuring device, the predetermined mark is displayed only on one of the plurality of operation condition selection candidates. Therefore, a small display space is required for displaying the already set contents. For this reason, it is possible to effectively use the display space of the display unit.

Next, by operating the keys 7a to 7d, the cursor 20 is moved to the display portion corresponding to the “range” for the CH “2”, and then the operation is changed to FIG. As shown, the range of channel 2 is changed to “50 mV”. Next, with the cursor 20 moved to the display portion corresponding to the “0 position” for CH “2”, the key 8 is pressed.
a, 8b, the jog dial 6a or the shuttle dial 6b is operated to set “0” for CH “2”.
Set value displayed on the display part corresponding to `` Position ''
For example, change to “29%”. In this state, when the key 8e of the function key section 8 is operated, each setting item for the channels 1 and 2 displayed on the channel setting screen 22 is determined.

After that, when the DISP key 5 of the operation section 3 is operated, a waveform display screen 21 is displayed on the display section 2 as shown in FIG. 6, and the channel is displayed in accordance with the operating conditions set on the channel setting screen 22. Signal waveforms W1a and W2a of the recording target signals measured by the measurement units UN corresponding to 1 and 2 are displayed, respectively. At this time,
To display the signal waveform for channel 2 with the amplitude of the signal waveform W2a enlarged to, for example, about 10 times,
By operating the HAN key 4, the channel setting screen 22 shown in FIG. in this case,
The amplitude value of the signal waveform W2a can be changed by any of the “range” and the “magnification (display magnification)” for the channel 2, and an example of changing the range will be described below.

When changing the range for channel 2 described above, by operating keys 7a to 7d, the cursor 20 is moved to the display area corresponding to "range" for CH "2", as shown in FIG. Move. At this time, a selection candidate group display screen 31 is displayed on the upper right of the display unit 2 as shown in FIG. In this case, the current setting value mark 32 is displayed on the selection candidate group display
Are displayed on the left side of the selection candidate (in this case, “50 m”) corresponding to the currently set value of the range. In the current set value mark 32, an operation condition (in this case, a range corresponds) corresponding to the selected candidate group is set after the power is turned on, and a signal waveform is displayed immediately before according to the set contents of the operation condition. This shows the settings that have already been made. In other words, the range selection candidate as the operating condition in which the current set value mark 32 is displayed means that the range is the set value when the signal waveform was displayed immediately before on the waveform display screen 21.

Therefore, the operator sets the current set value mark 32 on the selection candidate group display screen 31 and the amplitude value of the signal waveform W2a displayed on the waveform display screen 21. Thus, it is possible to quickly and accurately determine and select a set value of a range in which a signal waveform is displayed with a desired amplitude value. In this case, the keys 8a,

In this case, the currently set value (in this case, “29%”) for the display position of channel 2 is displayed on the current set value confirmation screen 33. Therefore, based on the displayed current setting value and the amplitude value of the signal waveform W2a displayed on the waveform display screen 21, the operator can display 0 for displaying the signal waveform W2a at a desired display position. The position can be set quickly and accurately. In this case, by operating the keys 8a, 8b, the jog dial 6a or the shuttle dial 6b, the CH
For example, “25%” is displayed on the display portion corresponding to “0 position” for “2”. In this state, the key 8e
By operating, each setting item whose setting has been changed for channel 2 is determined.

Thereafter, when the DISP key 5 of the operation unit 3 is operated, a waveform display screen 21 is displayed on the display unit 2 as shown in FIG. Signal waveforms W1a and W2b of the recording target signal measured by the measurement unit UN corresponding to the channels 1 and 2 are displayed. According to FIG.
