To convert the acquired RMS and channel sample data values into their primary val-
ues, the following formula must be applied:
• ADC Value is the primary value desired to be acquired. Can refer to either:
• RMS values (Trigger Cycle RMS, Trigger Cycle RMS, etc.)
• Sample values (Volts AN, Current IA, Volts BN, etc.)
• Calibration is the sample calibration value for corresponding channel.
• Ratio is either PT Ratio or CT Ratio (acquired from Programmable Settings)
• PT Ratio for voltage
• CT Ratio for current
For example, if you are looking for the primary Trigger RMS Va value and given the
following:
PT Numerator = 1200 V
PT Denominator = 120 V
CT Numerator = 1000 A
CT Denominator = 5 A
Trigger Cycle RMS Va = 4505
Trigger Cycle RMS Ia = 30133
Trigger Cycle RMS Vb = 5408
Sample Calibration Va = 42049
