Description/reference
Determines the full-scale input for the measurement; also affects
the accuracy of the measurements and the maximum signal that
can be measured. Refer to
Applies a wait period at the start of measurement to allow cables
and circuitry to settle for best accuracy. Refer to
page 2-137).
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to
number of displayed digits (on page 2-55).
compensation reduces or eliminates thermoelectric EMFs in
low-level resistance measurements. Refer to
ohms (on page 2-111).
Enables or disables open lead detection. When enabled, detects
open test leads, which can lead to inaccuracies in 4-wire sensing.
Controls the amount of time the input signal is measured
(aperture), which affects the noise and reading rate; see
aperture or NPLCs to adjust speed and accuracy
Determines if internal reference points are used to maintain
stability and accuracy. See
page 2-149).
Sets the number of aperture readings that are processed when a
measurement is requested.
Enables or disables line synchronization. When it is enabled, it
helps increase common-mode and normal-mode noise rejection.
Refer to Line cycle synchronization
Enables or disables dry circuit. When dry circuit is enabled, it limits
the open-circuit voltage to below 20 mV. When dry circuit is
enabled, offset compensation is automatically enabled. Refer to
Dry circuit ohms (on page 2-111).
