Connect the output side of the AC adapter to the
connector indicated as “DC LINE” on the GL800.
Use a flathead screwdriver to push the button
above the ground terminal while connecting the
grounding cable to the GL800. Connect the other
end of the cable to ground.

Grounding cable

Lead wire resistance should be 10 Ω or below per wire, and
equivalent among the three wires.
Shunt resistance
Ex: for current in the 4 to 20 mA range,
apply a resistance of 250 Ω (±0.1%) and
perform measurement in the 1 to 5 V range.
• Avoid electrical shock and short circuit accidents
・Do not apply voltage of AC33 Vrms or 60 VDC or above between the
analog input section and main unit (GND terminal), or to between each
analog channel.
・ Do not apply voltage of AC33 Vrms or 60 VDC or above to analog input
section (between + and - terminals).
・ Do not apply radio-frequency signals.
• Warming-up
The GL800 should be allowed to warm up with the power turned on for
approximately 30 minutes to achieve operation according to the specified
performance.
• Unused channels
Capacitors have been incorporated into the analog input circuit to increase the noise
elimination capability.
Therefore, if input terminal is open, or signals are not input to the terminal,
measured results may be influenced by signals from other channels. In such a case,
set input setting to “Off” or short circuit the + and – terminals.
If signals are input correctly, measured results are not influenced by other channels.

• 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 GL800’s GND to ground.
Ex 2: Connect GL800’s GND to measurement object's GND.
Ex 3: Operate GL800 with batteries (B-517).
Ex 4: In the AMP settings menu, set filter to any setting other than “OFF”.
Ex 5:
Set the sampling interval which enables GL800’s digital filter (see table below).

Channels* Sampling Interval which enables Digital Filter
*”Number of Measuring Channels” is the number of channels in which
input settings are NOT set to “OFF”.

Press the TIME/DIV key to change the time axis display range on the waveform screen.
This key enables SPAN, POSITION, and TRACE settings to be made independently for each
channel. Each time this key is pressed, the mode displayed in the waveform operation display
area changes in the sequence shown below. Use the and keys to select the channel, and
the and keys to change the setting values.
Press this key to switch to the next group consisting of 10 channels.

Displays digital values (default).
Used to make span settings (change the waveform
amplitude).
Used to make position settings (adjust the upper and
lower values of the waveform).
Used to make trace settings (set the waveform display to
On or Off).
Note: If the QUIT key is pressed when the GL800 is in the SPAN, POSITION, or
TRACE mode, the display returns to MONITOR mode.

• AMP Settings
Used to make the input, range, filter and other settings.
• Data Capture Settings
Used to make settings such as the sampling interval, data capture
destination, and calculations during data capture.
• Trigger Settings
Used to specify data capture start and stop conditions, and alarm conditions.
• User Settings
Used to set the names of the users of this device, and to change from one
