Tap the [Notch frequency] box, and then choose a power frequency from the list.
Choose a power frequency of your region.
50 Hz

60 Hz Sets the period to 16.67 ms.
An incorrect power frequency setting causes measured values to be unstable.

Tap the [NLPC] box, and then enter an integration time.
Define an integration time based on the power line cycle (PLC), which is the time equivalent to one period of
the power frequency.
0.1 to 0.9 , 1  to 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , 90 , 100
Example: When the power frequency is 50 Hz and NPLC is set at 10, the integration time is calculated to be
200 ms (= 20 ms × 10).
The instrument updates waveform data every 200 ms.

Tap the [Response] box, and then choose a data update interval from the list.
Off  Updates data at intervals of the integration time entered in the [NPLC] box.
On Updates the data at high speed by calculating moving averages.
