Dmm.measure.autozero.once() - Keithley DMM7510 Reference Manual

Section 8: TSP command reference

dmm.measure.autozero.once()

This function causes the instrument to refresh the reference and zero measurements once.
Type TSP-Link accessible
Function Yes
Usage
dmm.measure.autozero.once()
Functions
dmm.FUNC_DC_VOLTAGE
dmm.FUNC_AC_VOLTAGE
dmm.FUNC_DC_CURRENT
dmm.FUNC_AC_CURRENT
dmm.FUNC_TEMPERATURE
Details
This command forces a refresh of the reference and zero measurements that are used for the present
aperture setting for the selected function.
When autozero is set to off, the instrument may gradually drift out of specification. To minimize the
drift, you can send the once command to make a reference and zero measurement immediately
before a test sequence.
If the NPLC setting is less than 0.2 PLC, sending autozero once can result in delay of more than a
second.
