問題:
What is NPLC and why is it important?
答案:
NPLC is number of power line cycles. DC Voltage, DC Current, and Resistance measurement resolution, accuracy is reduced by power line induced AC noise. Using NPLC of 1 or greater increases AC noise integration time, and increases measurement resolution and accuracy, however the trade-off is slower measurement rates. For highest measurement accuracy NPLC of 100 is recommended.
