EU (Engineering Units):
These are the engineering units for the selected channel.
This has to match the physical sensor type. For example, displacement sensors
should have "um" or "mm", whereas accelerometer sensors should have "g".
•
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 Averaging), PtP (true
Peak to Peak) or “P” (true Peak to Peak / 2).
•
Comb. calc (Combination calculation):
The available combination calculations for channels
Ch X
and
Ch Y
of an
Absolute Shaft Vibration type are:
Ch X + Ch Y
Ch X – Ch Y
Ch X – Ch Y
The available combination calculations for channels
Ch X
and
Ch Y
of a
Temperature Difference type are:
Ch X – Ch Y
Ch Y – Ch X
•
Scale (Min & Max):
These are used to set the max/min values for the
measurement, including Modbus. It is also used to set the measured channel’s
display range on the small TFT on the front panel of the condition monitoring
module.
