Connect the AC Adapter
Connect the DC output of the AC adapter to the
connector marked as "DC LINE" on the GL840.
Connect the Grounding Cable
Use a flathead screwdriver to push the button above
the GND terminal while connecting the ground
cable to the GL840. Connect the other end of the
cable to ground.
Lead wire resistance should be
10  or less per wire, three
wires need to be same length.
Shunt resister
Ex: Current signal is converted to voltage using a
shunt register.
For 4 to 20mA current input, install the 250ohms
(0.1%)shunt resister to convert the signal to 1 to
5V.Note: Graphtec offers B-551 250ohm.
Connect to the Analog Input Terminals
CAUTION: Connect wires to the specified channel, the channel number is shown on top of the terminal block.
Connect the External Input/Output Cable
* The B-513 input/output cable for GL (sold separately) is required for connecting input/output signals.
(For logic/pulse input, alarm output, trigger input and external sampling pulse input)

Mounting SD CARD 2
CAUTION: To remove a SD card, push in gently to release the card before pulling.
The POWER LED blinks while GL840 is accessing the SD memory card.
* SD card must be unlocked.
< How to mount >
(1) Open the protective cover
to the SD CARD slot.
(2) Insert the SD memory
card until it clicks and is
firmly placed inside the
slot.
< How to remove >

Connect with PC
GL840 midi LOGGER complies with the EMC Directive the supplied ferrite core is attached to the USB cable.
When connecting with the USB cable, the USB driver must be installed to the PC. For information about how to
install, refer to the "USB Driver Installation Manual" in the supplied CD-ROM.
To connect a PC using a USB
cable, attach the supplied ferrite
core to the USB cable as shown.
To connect GL840 and PC, use a cable with A-type
and B-type connectors.

Safety Guide for using GL840
Maximum input voltage of standard terminal (B-564)
If a voltage exceeding the specified value goes into the instrument, the electrical
relay in the input will be damaged. Never input voltage level exceeding the
specified value at any moment.
< Between +/– terminals(A) >
• Maximum input voltage: 60Vp-p (Ranges set in 20mV to 2V)
110Vp-p (Ranges set in 5V 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
Maximum input voltage of Withstand High Voltage high-precision terminal (B-565)
If a voltage exceeding the specified value goes into the instrument, the electrical
relay in the input will be damaged.
Never input voltage level exceeding the specified value at any moment.
Warm-up
GL840 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.
< Between +/– terminals(A) >
• Maximum input voltage: 60Vp-p (Ranges set in 20mV to 2V)
110Vp-p (Ranges set in 5V to 100V)
< Between Channel to channel (B) >
• Maximum input voltage: 600Vp-p
• Withstand voltage: 600Vp-p
< Between Channel to GND (C) >
• Maximum input voltage: 300Vp-p
• Withstand voltage: 2300 VACrms at 1 minute

Noise countermeasures
If measured values fluctuate due to extraneous noise, run the following
countermeasures.(Results may vary according to types of noise issues.)
Ex 1 : Connect the GL840's GND input to ground.
Ex 2 : Connect GL840's GND to measurement object's GND.
Ex 3 : Operate GL840 with batteries (Option: two B-569 batteries).
Ex 4 : In the AMP settings menu, set filter to any setting other than "OFF".
Ex 5: Set the sampling interval which enables GL840’s digital filter
(see table below).
*1 Number of Measuring Channels is the number of active channels channels in which
input settings are set to a value and NOT to “OFF” .
*2 Temperature are not measured when the sampling interval is set to 50 ms or faster.
In the "OTHER" menu, the commercial power frequency to be used must be
set.
Set the AC power frequency to be used.
