2-wire resistance measure settings
The following options are available on the Measure Settings menu when the function is set to 2-wire
resistance.
Setting Description/reference
Range
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 Ranges (on page 3-3).
Auto Delay
Applies a wait period at the start of measurement to allow cables
and circuitry to settle for best accuracy. Refer to Auto Delay (on
page 2-137).
Display Digits
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to Setting the
number of displayed digits (on page 2-55).
Offset Compensation
Always set to off for 2-wire resistance. Refer to Offset-
compensated ohms (on page 2-111).
Integration Rate
Controls the amount of time the input signal is measured
(aperture), which affects the noise and reading rate; see Using
aperture or NPLCs to adjust speed and accuracy (on page 4-1).
Auto Zero
Determines if internal reference points are used to maintain
stability and accuracy. See Automatic reference measurements (on
page 2-149).
Count
Sets the number of aperture readings that are processed when a
measurement is requested.
Line Sync
Enables or disables line synchronization. When it is enabled, it
helps increase common-mode and normal-mode noise rejection.
Refer to Line cycle synchronization (on page 4-1).
