Chapter 3 Features and Functions
Measurement Configuration
Autozero
When autozero is enabled (default), the multimeter internally
disconnects the input signal following each measurement, and takes a
zero reading. It then subtracts the zero reading from the preceding
reading. This prevents offset voltages present on the multimeter's input
circuitry from affecting measurement accuracy.
When autozero is disabled, the multimeter takes one zero reading and
subtracts it from all subsequent measurements. It takes a new zero
reading each time you change the function, range, or integration time.
Applies to dc voltage, dc current, and 2-wire ohms measurements only.
Autozero is enabled when you select 4-wire ohms or ratio measurements.
The autozero mode is stored in volatile memory; the multimeter
automatically enables autozero when power has been off or after a
remote interface reset.
Front-Panel Operation: The autozero mode is set indirectly when you
set the resolution.
