Why are the measured voltage and temperature fluctuations not stable?
If the AC line frequency is set incorrectly, the digital filter will not work effectively.
Check the AC line frequency setting and match it to the power supply frequency in your area.
The setting can be made by pressing the [MENU] key and selecting "AC line frequency" on the
"OTHER" screen.
If the AC line frequency setting is correct, but the waveform is not stable, one of the possible reasons
is that the sampling interval may have an effect.
If the data fluctuates due to noise, set the sampling interval at which the digital filter is enabled.

.
The measured voltage and temperature fluctuations are not stable while recording data with external
sampling.
If the AC line filter is set to Disabled (Off) when external sampling is enabled (On), please change it to Enabled
(On), and measure at an external sampling interval greater than or equal to the fastest interval at which the
digital filter displayed in parentheses is enabled.
The fastest intervals are shown in the table below.
