General operation
DMM7510-901-01 Rev. B / May 2015 2-29
Continuity measure settings
The following options are available on the Measure Settings menu when the function is set to
Continuity.
Setting Description
Range
Always set to 1 kΩ when Continuity 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 Auto Delay (on
page 2-137).
Display Digits
Always set to 4.5 digits when Continuity is selected.
Limit 1 High Value
Sets the high value for limit 1. Limit 1 is automatically set to enable.
Refer to Limit testing and binning (on page 3-102).
Limit 1 Audible
Determines if the beeper sounds when the resistance is more than
or less than the limit 1 high value. Refer to Limit testing and binning
(on page 3-102).
Integration Rate
Always set to 0.006 PLC when Continuity is selected.
Auto Zero
Always set to off when Continuity is selected.
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).
Frequency measure settings
The following options are available on the Measure Settings menu when the function is set to
Frequency.
Setting Description
Range
Always set to auto when frequency 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 Auto Delay (on
page 2-137).
Display Digits
Always set to 6.5 digits for frequency.
Aperture
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).
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 frequency
measurements.
