1. Nominal Value: Obtain the standard reference component pre-measured
known value. The measured value = 100nH (Enter this value into the Test
Program for Load Compensation)
2. When the AT5600 performs a Load Compensation, it measures say 120 nH.
The ratio of Nominal Value / AT Measured Results is stored in the AT5600's
memory as the Load Compensation Ratio. Example, this case 100nH / 120
nH = 0.833.
3. Then, when the program is run,
The Displayed Result = Load Compensation Ratio * measured
value
In our case, 100nH = 0.833 * 120 nH
After you have selected short circuit, open circuit, or load compensation and
pressed the Run Button on the front panel, the tester will automatically perform all
the compensation measurements and retain the results in internal memory.
The compensation factors will then be applied to each transformer as it is tested.
