If you have preset measurement with respect to ground on switch S9, four
channel groups of four channels each are available. You can configure each
channel group separately for current or voltage measurement.
This is set 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 9-26:
