Checking the Outer Casing
Checking the Accessories
Setting and Checking the AC Line Frequency
After unpacking, check the GL220's Exterior to make sure that
there are no crack or other damage before use.
Set the AC line frequency inthe “OTHR” menu. This setting
(50 or 60 Hz) affects the noise reduction performance of the device.

Making Connections to the External Input/Output Terminals

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
<Between input terminal/GND (C) >
・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).

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 GL220
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
