Keysight DAQ970A User Guide

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.
Full and half bridge in Poisson arrangement
This section describes how to configure the selected channel for full and half Poisson bridge strain gage
measurements from the front panel.
1.
Connect bridge configuration source to the module's screw terminals.
