Driver Functions

hp4156b_execOffsetCancel

This function measures the zero offset data, and sets the zero offset function to ON.

The parameter 'channel' specifies the measurement channel (SMU or VMU).

If you define SMU for 'channel', the SMU must be set to the voltage force mode by

using the hp4156b_force function, before executing this function.

If you define VMU for 'channel’, the VMU must be set to the differential voltage

measurement mode by using the hp4156b_setVm function, before executing this

function.

Syntax ViStatus _VI_FUNC hp4156b_execOffsetCancel(ViSession vi, ViInt32 channel,

ViInt32 range);

Parameters vi Instrument handle returned from hp4156b_init( ).

channel Channel number of the unit to measure the zero offset data..

1 to 6 (SMU1 to SMU6), 23 (VMU1), or 24 (VMU2).

range Measurement range to measure the zero offset data
