50
Command Parameter:
= 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 based 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.
:RANGe Commands
:[UPPer]
Command syntax:
:VOLTage:AC:RANGe[:UPPer] Set measurement range for ACV
:VOLTage:DC:RANGe[:UPPer] Set measurement range for DCV
Command Parameter:
= 0.2, 2, 20, 200, 750 Expected reading is AC volts (ACV)
0.2, 2, 20, 200, 1000 Expected reading is DC volts (DCV)
DEFault 750 (ACV)
1000 (DCV)
MINimum 0 (All functions)
MAXimum Same as DEFault
Query:
:RANGe[:UPPer]? Query measurement range of the current function.
Description:
This command is used to manually select the measurement range for the specified measurement
function. The range is selected by specifying the expected reading as an absolute value. Select the
appropriate range to get the optimal reading of the measured device.
:AUTO
Command syntax:
:VOLTage:AC:RANGe:AUTO Set auto range for ACV
:VOLTage:DC:RANGe:AUTO Set auto range for DCV
