Precautions to Observe When Performing Measurement

Maximum input voltage

If a voltage exceeding the specified value is input, the semiconductor relay in the input section will be damaged. Never input a voltage exceeding the specified value even for a moment. <Between +/– terminals (A) > ・Maximum input voltage : 60Vp-p <Between input terminal/input terminal (B) >

・Maximum input voltage : 60Vp-p ・Withstand voltage　: 350 Vp-p at 1 minute

・Maximum input voltage : 60Vp-p ・Withstand voltage　: 350 Vp-p at 1 minute

Warming-up

GL220 requests to have approximately 30 minutes warm-up in order to have the specified performance.

Unused channels

The analog input section has high impedance. If it is open, measured value may vary due to noise. In such a case, set to "Off" unused channels in the AMP setting menu or short the + and – terminals.

Noise countermeasures

If measured values fluctuate due to extraneous noise, conduct the following countermeasures. (Results may differ according to noise type.) Ex 1 : Connect the GL220's GND to ground. Ex 2 : Connect GL220's GND to measurement object's GND. Ex 3 : In the AMP settings menu, set filter to any setting other than "OFF". Ex 4 : Operate GL220 with batteries (Option: B-517). Ex 5: Set the sampling interval which enables GL220’s digital filter (see table below).

Explanation of basic operation in the GL220 is completed. The GL220 has many other convenient functions. Please refer the next five pages for details.

GL220 Convenient Functions

and the timing of the end of a data capture operation.

The GL220 has various functions that enable it to be used more effectively. The selected three functions are described with details in the following.

Trigger Functions to Control Data Capture Start/Stop Operations

Trigger functions can be used to control the timing of the start of a data capture operation, and the timing of the end of a data capture operation.

Points to Remember

Here data capture is started in the condition as "Start data capture when the CH 1 temperature exceeds 20ºC".

　(1) Press the MENU key and open the "TRIG" menu.

　(2) Move the cursor to "Start Source" and select "Level".

For example... The trigger function performs operations such as the following:

• Start data capture when the voltage exceeds 1 V

• Stop data capture at 1:00 pm

• Perform control via external input

　(3) Move the cursor to the "Mode" parameter for the CH 1, and then select "Hi".

　(4) Move the cursor to the "Level" parameter next to the "Mode" parameter and then press the ENTER key. 　(5) The input box shown in the following screen is displayed. Select "20". Use the and keys to move to the cursor to the second digit from the right, and the and keys to change the value. Press the ENTER key.

Numerical value input box

Lower and upper limit for setting.

Waveform area for confirmationLower

•Use the and keys to change the values.

•Use the and keys to move the digit.

•Use the ENTER key to enter the value.

　(6) When the screen changes to the following screen, move the cursor to the button and then press the ENTER key.

　(7) The screen returns to the TRIG menu screen. Press the QUIT key to return the GL220 to the Free Running status. 　(8) Press the START/STOP key to start data capture. If the trigger condition has not been satisfied, the GL220 goes into the "Armed" status as shown on the following screen.

•Use the QUIT key to cancel the setting .

　　　When the trigger condition has been satisfied, data capture starts and the "Memory Recording" is displayed. Elapsed time for data capture appears.

Span, Position and Trace Functions to Adjust the Waveform Display

These functions enable to make adjustments in order to view individual channels more easily, and to delete waveforms that is not required to view in display.

Points to

The span, position and trace operations can be performed while the GL220

Remember

is in the Free Running status, while it capturing data, and while it is replaying data. The changes are applied to the displayed data only, the change is not affected to the captured data.

1.How to Make a Span setting

The Span parameter is used to adjust the amplitude of the input waveform. This setting is made in the aforementioned Free Running status.

　(1) Set the displayed span for CH 1 to 100ºC. 　(2) Press the SPAN/POSITION/TRACE key to select the SPAN mode.

The currently selected mode (SPAN, POSITION or TRACE) can be checked by looking at the "Waveform Operation Display Area".

　(3)　Use the and keys to make CH 1 active (enlarged display). 　(4)　Use the and keys to change the Span value. Here the value for span is set to 100ºC.

When this setting has been changed, the waveform screen scale will be set to "+100.0 to +0.0".

2.How to make a Position setting

The Position parameter is used to adjust the position of displayed waveform that is set by the upper and lower values.

　(1) Press the SPAN/POSITION/TRACE key to select the POSITION mode. 　(2)　Use the and keys to make CH 1 active (enlarged display). 　(3)　Use the and keys to set the Position value to "+80ºC to -20ºC". 　When this setting has been changed, the waveform screen scale will be set to "+80ºC to -20ºC".

3.How to make a Trace setting.

The Trace parameter can be used to specify the selected waveform to be visible or invisible on the display.

　(1) Press the SPAN/POSITION/TRACE key to select the TRACE mode. 　(2)　Use the and keys to make CH 1 active (enlarged display). 　(3)　Use the and keys to select Off. 　　When this setting has been changed, the CH 1 waveform is not displayed.
