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.
Making Connections to the Analog Input Terminals
CAUTION: Connect wires to the specified channel, the channel number is shown on top of the terminal block.

Shunt resister
Ex: The current is converted to the voltage in the
shunt register.
For 4 to 20mA current input, installing 250 ohms
(0.1%) resister for converting 1 to 5V.

Mounting of the SD CARD 2
CAUTION: The SD memory card is unlocked by pushing gently the SD memory card. Then, remove the SD
memory card.
When the optional wireless LAN unit is installed, the SD memory card cannot be mounted.
The POWER LED blinks while accessing to the SD memory card.
Connection of the USB cable
This midi LOGGER complies with the EMC Directive in the state when the supplied ferrite core is attached to the
USB cable.
When connecting to the PC with
the USB cable, attach the supplied
ferrite core to the USB cable as
shown in the following figure.
Using the cable with A-type and B-type connectors,
connect between the midi LOGGER and PC.
< How to remove >
(1) The SD memory card is
unlocked by pushing
gently the SD memory
card. Then, remove the
SD memory card.
USB cable
Ferrite core (Supplied)
< How to mount >
(1) Open the protective cover of
SD CARD 2.
(2) Push the SD memory card
until it clicks and is locked.
* Make sure that the
SD memory card is
not locked.

• The internal memory is displayed as the SD1 or SD CARD1
• The internal memory is not removable.
Precautions to Observe When Performing Measurement
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 (Range of 20mV to 1V)
110Vp-p (Range of 2V to 100V)
< 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
GL240 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 GL240's GND to ground.
Ex 2 : Connect GL240's GND 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 chahnnel or less
5 chahnnels or less
2 chahnnels or less
10 chahnnels or less

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

Descriptions of the Control Panel Keys
Press the [TIME/DIV] key to change the time axis display range on the waveform
screen.
2.TIME/DIV
This key enables SPAN, POSITION, and TRACE settings to be made
independently fo reach channel. Each time this key is pressed, 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
Points to Remember
Displays digital values (default).
Used to change span settings (change the waveform amplitude).
Used to change position settings (adjust the upper and lower values
of the waveform).
Used to change trace settings (set the waveform display to On or Off).
* If the [QUIT] key is pressed when the GL240 is in the SPAN, POSITION, or
TRACE mode, the display returns to MONITOR mode.

Press the [MENU] key to open a setup menu. Each time this key is pressed, the
setup screen tabs change in the sequence shown below.
3.MENU
Press the [QUIT] key to cancel the settings and return them to their default status.
If the device is in the Remote (Key Lock) status that the device is operated by the
computer via the interface, press this key to return the device to the normal
operating status (Local).
4.QUIT (LOCAL)
These keys are used to select menu setup items, to make span settings in the digital
display area, to move the cursors during a data replay operation, and so forth.
5.Keys (DIRECTION KEYS)
Press the [ENTER] key to enter the settings made in the setup menus, and to
confirm your settings.
6.ENTER
Used to move the cursor at high speed during replaying or change the operation
mode in the file box. Hold down both keys simultaneously for at least two seconds
to enable key lock status.
To cancel key lock status, press them again for at least two seconds.
The key lock status can be confirmed in whether or not the key lock lamp on the
monitor is lit in yellow.
* Pressing these keys simultaneously with the key + ENTER + key enables password protection
for the key lock operation.

CD.
8.START/STOP (USB DRIVE MODE)
Press the [REVIEW] key to replay captured data. If the GL240 is in the Free
Running status, data files that have already been captured are replayed. If the
GL240 is still capturing data, the data is replayed in a 2-screen format.
* A data replay operation will not be performed if data has not been captured.
10.REVIEW
Press the [CURSOR] key to switch between the A and B cursors during a data
replay operation.
If the Alarm setting has been specified as "Alarm Hold", press this key to clear the
alarm.
The alarm settings are made in the "TRIG" menu.
12.CURSOR (ALARM CLEAR)
It is used to operate the internal memory (SD1) and SD memory card (SD2), or
replace the SD memory card (SD2).

Press the [DISPLAY] key
9.DISPLAY
Points to Remember
•Waveform + Digital
This is the default screen when the GL240 is turned on,
and both waveforms and digital values are displayed.The
screen settings can also be changed by using the
[SPAN/POSI/TRACE] key.
•Expanded Waveform
Displays waveforms only.
* For more information, refer to the User's Manual in the
supplied CD.
•Digital + Calc
Displays large-size digital values and two types of
calculation processing results. The calculation settings are
made in the "DATA" menu.
Use the key or key to switch digital display
modes.
