2.13 Tests of the Plate with Clamp Terminals
(772063)
Tests
2.13.1 Insulation Resistance Test
2.13.2 Withstanding Voltage Test
2.13.3 ID Check
2.13.4 Between-Channel Measurement Error Test
2.13.5 Reference Junction Compensation Accuracy Test
Instruments Used
Same as section 2.12, “772061 10-ch Screw Terminal Block.”
2.13.1 Insulation Resistance Test
Same as section 2.12, “772061 10-ch Screw Terminal Block.”
However, when applying voltages to input terminal to earth, do so on the MX100 or
equivalent. Also, after attaching the module to the base plate, always fasten with screws.
2.13.2 Withstanding Voltage Test
Same as section 2.12, “772061 10-ch Screw Terminal Block.”
However, when applying voltages to input terminal to earth, do so on the MX100 or
equivalent. Also, after attaching the module to the base plate, always fasten with screws.
2.13.3 ID Check
Same as section 2.12, “772061 10-ch Screw Terminal Block.”
2.13.4 Between-Channel Measurement Error Test
Same as section 2.12, “772061 10-ch Screw Terminal Block.”
2.13.5 Reference Junction Compensation Accuracy Test
Always use terminal covers.
Procedure
1. Allow a warm-up of 30 minutes or more.
2. As shown in the figure below, use slots 0 through 4 and install the dummy module
in the outer-most slot.

3. Measure the 0°C standardized temperature tank at the range for Type-T
thermocouples. Measure on channel 4, and confirm that the result lies within 0°C
± 0.5°C.
