FETCH & MEASURE Sub-system
FETCh? {<CRD1>{,<CRD2>{, … {,<CRD10>}}}}}}
MEASure? {<CRD1>{,<CRD2>{, … {,<CRD10>}}}}}}
Type: Channel-Specific.
Description: This command lets the user get measurement data from the Power
Meter. Two measurement commands are available: MEASure and
FETCh. MEASure triggers the acquisition of new data before
returning data. FETCh returns the previously acquired data from
measurement buffer. The return could be -1, -2, -3 and <NR2>.
-1: The first time integrated calculation is not complete yet.
-2: RCE represents “range change error” when integration process
is executing.
-3: Invalid data when OVR、OCR、OCP occur.
