AC voltage measure settings
The following options are available on the Measure Settings menu when the function is set to AC
voltage.
Setting
Description
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
(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
Display Digits
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to
(on page 2-55).
Detector Bandwidth
Sets the detector bandwidth. Refer to
Integration Rate
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
(on page 4-1).
Auto Zero
Determines if internal reference points are used to maintain
stability and accuracy. See
Automatic reference measurements
page 2-149). Auto Zero is always on when Detector Bandwidth is 3
Hz or 30 Hz.
Count
Sets the number of aperture readings that are processed when a
measurement is requested.
Line Sync
Line synchronization is always off for AC voltage measurements.
Unit
Allows voltage to be measured in volts or decibels. Refer to
(on page 2-98).
Decibel Reference
Sets decibel reference point; this setting is only available when Unit
is set to Decibel. Refer to
Show voltage readings in decibels
