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

GL820 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 GL820's GND to ground. Ex 2 : Connect GL820'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 GL820 with batteries (Option: B-517). Ex 5: Set the sampling interval which enables GL820’s digital filter (see table below).

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.

　(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.

Span, Position and Trace Functions to Adjust the Waveform Display

The span, position and trace operations can be performed while the GL820 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.

Points to Remember

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.

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