Period measure settings
The following options are available on the Measure Settings menu when the function is set to Period.
Setting
Description
Range
Always set to auto when period is selected
.
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
Always set to 6.5 digits for period.
Aperture
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).
Count
Sets the number of aperture readings that are processed when a
measurement is requested.
Threshold Range
Indicates the expected input level of the voltage signal. You can
also set the threshold range to Auto.
Threshold Level
Determines the signal level where the instrument makes period
measurements.
Diode measure settings
The following options are available on the Measure Settings menu when the function is set to Diode.
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). Always set to
10 V for diode test.
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).
Bias Level
Sets amount of current that is sourced by the instrument to make
measurements.
Limit 1 Low Value
Sets the low value for limit 1. Refer to
Limit 1 Audible
Determines if the beeper sounds when the measurement is more
than or less than the limit 1 high value. Refer to
(on page 3-102).
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
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
(on page 4-1). Always set to off
for diode test.
Limit 1 High Value
Sets the high value for limit 1. Refer to
