Related to a measuring device.

[0002]

2. Description of the Related Art As a measuring device of this kind, the applicant has already developed a waveform display device 51 shown in FIG. As shown in the figure, the waveform display 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. Various operation switches such as a reference numeral 6a, a shuttle dial 6b, a cursor moving key unit 7, and a function key unit 8 are provided. In the waveform display device 51, a plurality of measurement unit insertion slots (not shown) for inserting measurement units capable of various kinds of 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 display device 51 assigns a channel number to the inserted measurement unit according to a predetermined rule. Therefore, the operator sets the operating conditions such as the input range and the display magnification for each assigned channel, and thereby causes the waveform display device 51 to output the voltage, current, and current measured by the measurement unit corresponding to the channel. Various signal waveforms such as temperature and distortion can be displayed on the display unit 52, printed by a printer (not shown), recorded on a floppy disk, and the like.

In the waveform display device 51, for example, when the input range for the channel 2 is set to 5 mV, the user first operates the CHAN key 4 of the operation unit 53, as shown in FIG. The setting screen 62 is displayed on the display unit 52. Next, by operating the respective keys 7a to 7d of the cursor moving key unit 7, the display unit 5 is displayed.
The cursor 60 is moved to a display portion corresponding to the “range” of the CH “2” displayed in No. 2 (the same figure shows a state where the cursor 60 has already been moved). Next, the keys 8a,
8b, jog dial 6a or shuttle dial 6b
To change the range of channel 2 to “5 m
V ". In this state, the function key section 8
By operating the key 8e, the input range of the channel 2 is changed to "5 mV". After this, DISP key 5
Is operated, the waveform display screen 61 is displayed as shown in FIG.
Is displayed on the display unit 2, and the waveform display screen 61 displays the signal waveform of the recording target signal corresponding to the channel 2 with an amplitude corresponding to the input range whose setting has been changed.

On the other hand, when removing noise of a signal to be recorded inputted to the channel 2, each key 7 a of the cursor moving key unit 7 is displayed with the channel setting screen 62 displayed on the display unit 2. By operating ~ 7d, the cursor 60 is moved to the display part corresponding to the "filter" for CH "2" as shown in FIG. next,
By operating the key 8a of the function key section 8 to set the function of the noise filter to "ON",
The key 8e is operated. Accordingly, the noise filter functions for channel 2, and the noise filter removes noise superimposed on the recording target signal input to channel 2. Thereafter, by starting recording of the recording target signal by a predetermined operation, the recording target signal input to each measurement unit is recorded on a floppy disk or the like in correspondence with the assigned channel number.

[0005]

However, the waveform display device 51 already developed by the applicant has the following points to be improved. First, in the waveform display device 51, for example, when setting the operating conditions for each channel, when the channel setting screen 62 is displayed on the display unit 52, the cursor 60 is located at any position on the channel setting screen 62. It is difficult for the operator to immediately determine whether is displayed. For this reason, there is a possibility that the operator may hinder rapid movement of the cursor 60 to a display portion corresponding to a setting item to be changed by the operator, or hinder accurate setting of operating conditions and the like. is there.

Secondly, on the channel setting screen 62 and the like, a plurality of setting items are displayed in a matrix in a vertically and horizontally arranged order. For this reason, when a large number of channels are displayed as the number of measurement units is increased, when the cursor 60 is moved by key operation, the operation condition items and channel numbers corresponding to the display position of the cursor 60 after the movement are displayed. The operator may erroneously determine an operation condition setting item due to an illusion in a row direction or a column direction. Specifically, for example, when an attempt is made to change the setting of the “range” for channel 2, the “range” for channel 3 is incorrectly set due to the illusion in the column direction, or the “0 position” is set. If the user tries to change the range, an illusion in the column direction may cause an erroneous setting of the “range”.

Third, in the waveform display device 51, the display unit 5
Since the contents of the setting items displayed in 2 are displayed with a small number of points, there is a problem that it is difficult to read the contents before and after the setting when performing the setting operation on the channel setting screen 62 or the like. In this case, for example, it is possible to display with a large number of points. However, for example, when all the setting values of the respective operating conditions corresponding to a plurality of channels are displayed with a large number of points, it is necessary to enlarge the display screen of the display unit 52,
This leads to an increase in the size of the device. In addition, when the number of channels displayed on one screen is reduced, the operator is forced to switch screens more than necessary.

The present invention has been made in view of such improvements, and has as its main object to provide a measuring device capable of performing a quick and accurate setting operation. It is another object of the present invention to provide a measuring device capable of easily reading settings and the like while keeping the device small.
