Description:
The integration period (measurement speed) for the basic measurement functions (except
Frequency and Period) is set using the:NPLCycles command. NPLC(Number of Power Line Cycles)
expresses the integration period by basing it on the power line frequency. For example, for a PLC of
1, the integration period in seconds would be1/60 (for 60Hz line power) which is 16.67 msec.
