GenComm Page 6 - Derived Instrumentation
NOTE:- Derived instrumentation values can only be read from a 550 or 555 module fitted
with the Power measurement option. This is also sometimes referred to as “Enhanced
instrumentation”.
Attempting to read these values from a “basic” instrumentation module will return an
“unimplemented” response.
