What is "1 PLC" of integration time in the measurement speed setting?
QI'm using the Precision DC Voltmeter DM7275. What is the unit of integration time "PLC" in the measurement speed setting?
A
PLC stands for Power Line Cycle, where 1 PLC is equivalent to the duration of one cycle of the
power being supplied to the instrument. In areas with 50 Hz power, 1 PLC = 1/50 = 20 ms, while
in areas with 60 Hz power, 1 PLC = 1/60 = 16.7 ms.
In the Precision DC Voltmeter DM7275, the unit of integration time can be selected between either "ms" or "PLC".
