surement. Measurement integration time depends on the power of linear cycles (NPLC). If the input power frequency is 60Hz, then the measurement will be required 1NPLC 1 / 60 seconds, that 16.667ms. Determines the integration time mode - digital converter (ADC) for input signal of the time, it reflects the speed and accuracy trade-off between the two.
Typical VF test soak time from 1 ms to 5 ms range, IL test is 5 milliseconds to 20 milliseconds. Use shorter test time, you can reduce the heat ca
