Auto Zero - Autozero provides the most accurate measurements, but requires additional measurement
time to perform the zero measurement. With autozero enabled (On), the instrument internally measures
the offset following each measurement. It then subtracts that measurement from the preceding reading.
This prevents offset voltages present on the instrument’s input circuitry from affecting measurement accur-
acy. With autozero disabled (Off), the instrument measures the offset once and subtracts the offset from all
subsequent measurements. The instrument takes a new offset measurement each time you change the
function, range, or integration time. (There is no autozero setting for 4-wire measurements).
Delay - Selects whether the delay between channels in the scan list will be automatically or manually selec-
ted. By selecting Auto, instrument will automatically determine the channel delay based on measurement
function, range, integration time, and AC filter setting. By selecting Time, the specified delay (time in
seconds) is inserted between the relay closure and the actual measurement on each channel, in addition to
any delay that will implicitly occur due to relay settling time.
Direct resistive method
This section describes how to configure the selected channel for direct 2-wire and 4-wire strain gage meas-
urements from the front panel. The measurement configurations for 2-wire and 4-wire direct resistive are
same, below descriptions explained by using 2-wire resistance measurements.
