Current/Voltage	If you have preset differential measurement on switch S9, two channel
Measurement for	groups of four channels each are available. You can configure each channel
Individual Channel	group separately for current or voltage measurement.
Groups	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
