Description This command is used to set the integration period (speed) for mea-
surements. 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 would be 1/60 (for
60Hz line power) which is 16.67
msec.
Note that this is a global command. Thus, if you set the speed for
voltage measurements to 10 PLC, then current and resistance will
also set to 10
PLC.
NOTE For the Model 2430 Pulse Mode, speed can be set from 0.004 to 0.100 PLC.
