Declaration
long AutoZero;
Description
The auto-zero mode. In general, the auto-zero capability of a DMM normalizes all measurements based on a zero reading. When auto-zeroing is enabled, the DMM internally disconnects the input signal and takes a zero reading. The DMM then subtracts the zero reading from the measurement. This prevents offset voltages present in the DMM's input circuitry from affecting measurement accuracy.
The following list includes valid values:
- CNiIviDmm::OffAutoZero - Disables the Dmm from taking any more zero readings The Dmm subtracts the last zero reading from all subsequent values it measures.
- CNiIviDmm::OnAutoZero - Configures the Dmm to take a zero reading for each measurement. The Dmm subtracts the zero reading from the value it measures.
- CNiIviDmm::OnceAutoZero - Configures the Dmm to take a zero reading immediately. The Dmm then subtracts this zero reading from all subsequent values it measures.
