Settings
The Test Settings dialog allows for user preference and test sequence settings.
The user can also reset the software to factory default settings by pressing the
Factory Settings button in the lower right corner.
General
Under the general section you can change the default line frequency. Specify if
you want to display the values as power factor or tan-delta. You can also change
the integration time between 3 and 200 seconds or set it to automatic.
Power Factor/Tan-Delta
Here you can select either frequency variation (default) or line sync reversal
for noise suppression. If no suppression is selected, you are allowed to vary
frequency from 1 to 500 Hz. For optimum results, frequency variation is
preferred.
