Initiating an Analog Channel

The following table shows the physical metrics of analog channels.

1 For Casing vibration type, the Detection of "RMS" is recommended if the Math Method is "single integration".
2 Detection types are true types; PtP (true peak to peak), P ("true peak to peak" /2), RMS (true root mean square
averaging)
3 Analog measurement type Other does not allow a user defined EU. Instead an EU can be selected from the list of
predefined engineering units.
