Acquisition

Acquisition is to set the combined measurement acquisition properties based on the
combined measurement type.


EU (Engineering Units): These are the engineering units for the selected combined
channel (final measurement result). This must be the same as the underlying
analogue channels.

Detection: This is the type of Signal Rectification that is to be used in processing
the returned signal. This can be set to "RMS" (true Root Mean Square Averaging),
PtP (true Peak to Peak) or "P" (true Peak to Peak / 2).

Comb. calc (Combination calculation):

Scale (Min & Max): These are used to set the max/min values for the
measurement, including Modbus. This also sets the channel's min/max achievable
values, on the CMM front panel display.
