Excitation Current
Here you can select either frequency variation (default) for noise suppression
or no suppression where frequency can now be varied from 1 to 500 Hz. Please
note that lower frequency results in higher excitation for same voltage, and so it
is preferred to maintain frequency variation or no suppression for this test.
Auto Tip-up Test
Set the kV/step for the auto tip-up test. The software will automatically increase
the voltage by the increment set in this box until the entered test voltage selected
in the main screen is reached.
You can select either frequency variation for noise suppression or no
suppression which allows you to vary frequency for this test.
Results
Specify if you want the measured values presented as either 10 kV equivalent or
the actual measured values.
Frequency Sweep
Set frequencies at which the frequency sweep will be made. The default
frequencies selected (470 220 110 70 40 20 10 4.64 2.15 Hz) allow optimum
sweep results as well as optimum test points for use in Individual Temperature
Correction (used in PowerDB Forms).
Manual
Select the noise suppression mode to be used during manual measurements. If
no interference is selected, one can vary frequency from 1-500 Hz in this testing.
Language
Set the language for the user interface of the software.
