Setting the type of
measurement
Measurement with respect to ground/differential measurement
The type of measurement (with respect to ground or differential
measurement) is set with switch S9. The switch settings relate to the
locations on the module shown in Figure 9-27:

for individual channel groups
If you have preset differential measurement on switch S9, two channel
groups of four channels each are available. You can configure each
channel group separately for current or voltage measurement. You set
this with switches S5, S6, S7 and S8. Switches S5 and S7 allow three
settings (left, midpoint and right); switches S6 and S8 allow two
settings (left and right). The switch settings relate to the locations on
the module shown in Figure 9-27:
