To enable, enable once, or disable Auto Zero:

Note Notes
  • The NI 4050 does not support Auto Zero.
  • The NI 4060 does not support the ONCE setting.
  • The NI 4065 only supports the ON setting. For NI 4065 devices, Auto Zero is always ON. Auto Zero is an integral part of the signal measurement phase and adds no extra time to the overall measurement.

LabVIEW—Use niDMM Configure Auto Zero.

CVI, C++, or Visual Basic—Use niDMM_ConfigureAutoZeroMode.



AUTO (default)-1NI-DMM chooses the Auto Zero setting based on the configured function and resolution.
OFF 0Disables Auto Zero.
ON 1The DMM internally disconnects the input signal following each measurement and takes a zero reading. It then subtracts the zero reading from the preceding reading.
ONCE 2The DMM internally disconnects the input signal for the first measurement and takes a zero reading. It then subtracts the zero reading from the first reading and the following readings.
