Safety Guide for using GL240
Maximum input voltage
If a voltage exceeding the specified value goes into the instrument, the electrical
relay in the input will be damaged. Never input a voltage exceeding the specified
value at any moment.
< Between +/– terminals(A) >
• Maximum input voltage: 60Vp-p (Range of 20mV to 1V)
110Vp-p (Range of 2V to 100V)
< Between Channel to channel (B) >
• Maximum input voltage: 60Vp-p
• Withstand voltage: 350 Vp-p at 1 minute
< Between Channel to GND (C) >
• Maximum input voltage: 60Vp-p
• Withstand voltage: 350 Vp-p at 1 minute
Warm-up
GL240 requires approximately 30 minutes warm-up time to deliver the optimum
performance.
Unused channels
The analog input section can frequently have cases of impedance.
Left open, measured value may fluctuate due to noise.
To rectify, set unused channels to "Off" in the AMP setting menu
or short the + and – terminals for better result.
Noise countermeasures
If measured values fluctuate due to extraneous noise, run the following
countermeasures.(Results may vary according to noise type.)
Ex 1 : Connect the GL240's GND input to ground.
Ex 2 : Connect GL240's GND input to measurement object's GND.
Ex 3 : Operate GL240 with batteries (Option: B-569).
Ex 4 : In the AMP settings menu, set filter to any setting other than "Off".
Ex 5: Set the sampling interval which enables GL240’s digital filter (see table below).

1. Starting data capture
Trigger functions can be used to control the timing of the start of a recording,
and the timing of the end of a recording.
Span, Position and Trace Functions to Adjust the Waveform Display
Key Pointers
The span, position and trace operations can be performed while the GL240 is in
the Free Running mode, while it is recording data, replaying data.
The changes are applied to the displayed data only, and this change dose not
affect the recorded data.
1. How to change the Span setting
The Span parameter is used to adjust the amplitude of the input waveform.
This setting is made in the Free Running mode.
(1) Set the displayed span for CH 2 to 100°C.
(2) Push the [SPAN/POSI/TRACE] key to select the SPAN mode.
2. How to change the Position setting
The Position parameter is used to adjust the position of displayed waveform
set by the upper and lower values.
(1) Push the [SPAN/POSI/TRACE] key to select the POSITION mode.
(2) Use the and keys to make CH 2 active (display enlarges on the
selected channel).
(3) Use the and keys to set the Position value to "+80.0°C to -20.0°C".
When this setting is changed, the waveform screen scale will be set to
"+80.0°C to -20.0°C".
(3) Use the and keys to make CH 2 active (display enlarges on the
selected channel).
(4) Use the and keys to change the Span value. Here the value for
span is set to 100°C.
When this setting is changed, the waveform screen scale will be set to
"+100.0°C to +0.0°C".
Key Pointers
The currently selected mode (SPAN,
POSITION or TRACE) can be checked by
looking at the "Waveform Operation Display
Area".
3. How to change the Trace setting.
The Trace parameter can be used to specify the selected waveform to be
visible or invisible on the display.
(1) Push the [SPAN/POSI/TRACE] key to select the TRACE mode.
(2) Use the and keys to make CH 1 active.
(3) Use the and keys to select Off.
When this setting is changed to Off, the CH 1 waveform will not be
displayed.
