If the CDN will be used for multiple test levels (1 Vrms, 3 Vrms, 10 Vrms,
etc.), calibration should be performed at the highest test level.
Calibration data for the lower test levels can then be calculated as shown
in Equation 5.

For instance, if the calibration was performed for a test level of 10 Vrms,
and the offset is needed for a test level of 3 Vrms:
The offset factor calculated above can then be applied to the calibration
results at the higher test level using Equation 6.
