Test 2-2: DC Isolation Test

This test verifies that sufficient DC isolation exists between various points on the switch module. The DMM used should be capable of measuring up to at least 1 GΩ. If the DMM indicates an overload, record the reading as ">Rmax", where Rmax is the highest resistance that the DMM can measure. If the DMM is a 3458A, for example, the reading should be written as ">1.2 GΩ".

Normally Open to

Common 1. Hardware Connections

Figure 2-4. DC Isolation Test (NO Channels to Common)

2.Equipment Setup

•Set DMM to: 2-wire ohms, 1 GΩ range.

•Send *RST to the switch to open all NO contacts.

3.DC Isolation Reading

•Trigger the DMM and record the reading.
