Connecting the AC Adapter
Connect the DC output of the AC adapter to the
connector indicated as "DC LINE" on the GL240.
Connecting the Grounding Cable
Use a flathead screwdriver to push the button above
the GND terminal while connecting the grounding
cable to the GL240. Connect the other end of the
cable to ground.
Connect to the Analog Input Terminals
CAUTION: Connect wire to the designated channel, where individual channels are numbered.
Connect the External Input/Output Terminals
(For logic/pulse input, alarm output, trigger input, external sampling pulse input)
* Requires B-513 pulse/logic cable.

Connect with PC
GL240 midi LOGGER complies with the EMC Directive when the supplied ferrite core is attached to a USB
cable.
To connect a PC using a USB
cable, attach the supplied ferrite
core to the USB cable as shown.
To connect GL240 and PC, use a cable with A-type
and B-type connectors.
< How to remove >
(1) The SD memory card is
released by pushing
gently on the card.
Then, pull to remove the
card.

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 Channel or less
5 Channels or less
2 Channels or less
10 Channels or less

Allowed Sampling
Interval
Sampling Interval which
enables Digital Filter
*1 Number of Measuring Channels is the number of active channels in which input settings
are NOT set to “Off” .
*2
Temperature cannot be set when the active sampling interval is set to 10 ms, 20 ms or 50 ms.

Descriptions of the Control Panel Keys
Push the [TIME/DIV] key to change the time axis display range on the waveform
screen.
2.TIME/DIV
The key allows SPAN, POSITION, and TRACE settings to be made independently
for each channel. When the key is pushed, the display mode changes in the
sequence shown below. Use the and keys to select the channel,
and the and keys to change the setting values.
1.SPAN/POSI/TRACE
Key Pointers
Displays digital values (default).
Change the span settings (change the waveform amplitude).
Change the position settings (adjust the upper and lower values of the
waveform).
Change the trace settings (set the waveform display to On or Off).
* If the [QUIT] key is pushed when the GL240 is in the SPAN, POSITION, or
TRACE mode, the display returns to MONITOR mode.

Push the [MENU] key to open a setup menu. As you push the [MENU] key the
setup screen tabs change in the sequence shown below.
3.MENU
Push the [QUIT] key to cancel the settings and return to the default status.
If GL240 is in a Remote (Key Lock) status and is run by a computer via a USB or
WLAN interface, push the key to return to a normal operating status. (Local).
4.QUIT (LOCAL)
Direction keys are used to select menu setup items, to make span settings in the
digital display area, or to move the cursors during a data replay operation.

Push the [ENTER] key to submit the setting and to confirm your settings.
6.ENTER
Fast forward and rewind keys are used to move the cursor at high speed during
replay or change the operation mode in the file box. Hold down both keys
simultaneously for at least two seconds to lock the key bottons. (Orange key at the
top right of window indicates locked status).
To cancel key lock status, push both key again for at least two seconds.
* Pushing these keys simultaneously with the key + ENTER + key enables password protection
for the key lock operation.
