Enable or disable auto range

Query auto range

Specify reference (0 to 20e6)

Enable or disable reference

Query state of reference

Speed Commands

: NPLCycles <n>

Command System:

:RESistance:NPLCycles <n> Set NPLC for Ω

Command Parameter:

<n> = 0.1, 1, 10 Set power line cycles per integration

DEFault 1

MINimum 10

MAXimum 0.1

Query:

:NPLCycles? Query programmed NPLC value

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 be 1/60 (for 60Hz line power) which is 16.67 ms.
