Click the area that includes [Notch frequency].
The setting dialog box appears.

Click the [Notch frequency] box, and then choose a power frequency from the list.
Choose a power frequency of your region.
50 Hz
Sets the period at 20 ms.
60 Hz Sets the period at 16.67 ms.
An incorrect power frequency setting causes measured values to be unstable.

Click the [NLPC] box, and then enter an integration time.
Dene an integration time based on the power line cycle (PLC), which is the time equivalent to one period of
the power frequency.

, 10, 100
Example: When the power frequency is 50 Hz and NPLC is set at 10, then 20 ms × 10 = 200 ms is obtained.
The instrument updates measured data every 200 ms.
(Increasing NPLC may reduce uctuation in measured values caused due to exogenous noise or an EMC
environment.

Click the [Response] box, and then choose a data update interval from the list.
Off
Updates data at intervals the time entered in the [NPLC] box.
On Calculates moving averages every 1 PLC and updates the data.

DC
Outputs a DC signal.
SIN Outputs a sine wave signal.

Congure the advanced output settings.
DC voltage
Allows you to enter a DC voltage.
−10.000 V to +10.000 V
Frequency
Allows you to enter a frequency of the output sine wave.
0 Hz to 20000 Hz
Amplitude
Allows you to enter an amplitude of the output sine wave.
Accuracy of the output voltage, which consists of amplitude and an offset value, is guaranteed in the
range of −10 V to +10 V.
An output waveform will appear with its upper parts limited to about +14 V and lower about
−14 V when the sum of the amplitude and offset value is set to out of the accuracy-guaranteed
range.
