(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.
