2. Push the terminal unit in the direction shown until it is securely locked.
Connecting the Grounding Cable
Use a flathead screwdriver to push the button above the GND terminal while connecting the grounding cable to the GL860.
Connect the other end of the cable to ground.
Connecting the Analog Input Terminals
CAUTION
- Connect to any terminal according to the picture above.
For the connection to the screwless terminal, refer to the instruction manual (PDF). - B-563/B-563SL/B-563SL-30 do not support RTD input.
Connecting the External Input/Output Terminals
The B-513 input/output cable for the GL series (optional item) is required for connecting external input/output signals. (logic/pulse input, alarm output, trigger input, external sampling pulse input)
Internal memory
- The internal memory is not removable.

Safety Guide for using GL860
Warm-up
GL860 requires approximately 30 minutes warm-up time to deliver the optimum performance.
Unused channels
For unused CHs, turn off the input setting or short-circuit the +/- terminals.
If an unused analog input section is open, it may appear that signals are being generated on other CHs.
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.

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 GL860’s GND input to ground.
Ex 2 : Connect GL860’s GND input to measurement object’s GND.
Ex 3 : Operate GL860 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 GL860’s digital filter (see table below).
| Number of Measuring Channels*1 | Allowed Sampling Interval | Sampling Interval which enables Digital Filter |
| 1 Channel | 5ms or slower*2 | 50ms or slower |
| 2 Channel | 10ms or slower*2 | 125ms or slower |
| 3 to 4 Channel | 20ms or slower*2 | 250ms or slower |
| 5 Channel | 50ms or slower*2 | 250ms or slower |
| 6 to 10 Channel | 50ms or slower*2 | 500ms or slower |
| 11 to 20 Channel | 100ms or slower | 1s or slower |

*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.
In the “OTHER” menu, the commercial power frequency to be used must be set.
Set the AC power frequency to be used.
| Select items | Description |
| 50Hz | Area where the power frequency is 50 Hz. |
