2.5 Convenient function
Filter function (Rejecting noise)
This function allows you to reject unneeded frequency compo-
nents such as high-frequency noise.

During resistance measurement
Using the filter function when there is a significant amount
of variation in measured values during resistance measure-
ment will cause the measured values to stabilize.
*Note that noise rejection cannot be used when the [
mark is lit up.
During current measurement
Using the filter function enables a low-pass filter, causing
the harmonic component to be eliminated from measured
values. Widespread use of switching power supplies and
inverters has led to cases where harmonic components are
superimposed on current waveforms; the filter function is
effective in such cases. Canceling the filter function dis-
ables the low-pass filter, allowing measurement of current
including harmonic components.
