Connection Procedures

Connect the DC output of the AC adapter to the connector indicated as “DC LINE” on the GL260.

Use a flathead screwdriver to push the button above the GND terminal while connecting the grounding cable to the GL260.
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.

Internal memory
The internal memory is not removable.

Mounting SD Card

< How to remove >
The SD memory card is released by pushing gently on the card. Then, pull to remove the card.

CAUTION: To remove a SD memory card, push in gently to release the card before pulling. When the optional wireless LAN unit is installed, the SD memory card cannot be mounted. The POWER LED blinks while accessing the SD memory card.

Connect with PC

To connect a PC using a USB cable, attach the supplied ferrite core to the USB cable as shown.
To connect GL260 and PC, use a cable with A-type and B- type connectors.

GL260 midi LOGGER complies with the EMC Directive when the supplied ferrite core is attached to a USB cable.

Safety Guide for using GL260

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
GL260 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 GL260’s GND input to ground.

Ex 2 : Connect GL260’s GND input to measurement object’s GND.
Ex 3 : Operate GL260 with batteries (Option: B-573).
Ex 4 : In the AMP settings menu, set filter to any setting other than “Off”.

Ex 5 : Set the sampling interval which enables GL260’s digital filter (see table below).

Number of Measuring Channels *1	Allowed Sampling Interval	Sampling Interval which enables Digital Filter
1 Channel or less	10 msec or slower *2	50 msec or slower
2 Channel or less	20 msec or slower *2	125 msec or slower
5 Channel or less	50 msec or slower *2	250 msec or slower
10 Channel or less	100 msec or slower	500 msec or slower

Number of Measuring Channels is the number of active channels in which input settings are NOT set to “Off”.
Temperature cannot be set when the active sampling interval is set to 10 ms, 20 ms or 50 ms.
