(4) Setting power supply noise filter
Set the noise filter in “FILTER: OFF/ON.”
OFF: The filter is not used (High-speed changeover mode: Fast)
ON: The filter is used Low noise mode: Slow) Standard setting
Power Supply Noise Filter
Noise of measuring voltage output greatly affects the measurement accuracy in
measurement of samples which have a high electrostatic capacity such as
capacitors. For this reason, the meter is equipped with a filter to reduce noise
of measuring voltage output.
In regular measurement, stable measurement is possible by turning the filter on.
The condition in which the filter is turned on is called the “low-noise mode.”
The low-noise mode enables stable measurement with less noise. However,
one disadvantage with this mode is that the changeover speed of measuring
voltage becomes slow depending on the filter response time.
Select the high-speed changeover mode with the filter turned off in
measurement that requires fast changeover of measuring voltage.
The low-noise mode with the filter turned on is set during preshipment
inspection of the meter at the HIOKI factory

* When using the charging terminal, make sure that total current does not exceed the
capacity.
* A voltage drop will result with the voltage source if the total load current exceeds the
current capacity of the voltage source.
* Continuous rating of current capacity is specified in parentheses ( ).
* A voltage drop will result with the voltage source if the rating is exceeded by a
continuous load
