4.3 Filter Function (FILTER)
The inuence of high-frequency noise can be reduced with
the low-pass lter (digital lter). The lter function is useful for
measurements such as standard waveform measurement (AC
voltage measurement) of the inverter secondary side.
This function can be used when performing the AC voltage
measurement, AC and DC voltage automatic judgment, AC current
measurement, and clamp AC current measurement. The passband
setting for the low pass lter can be selected.
WARNING
Select a proper passband setting when
measuring the AC voltage.
Using the instrument to make measurements with
inappropriate settings could cause the user to fail to
realize the presence of hazardous input, resulting in
electric shock. Additionally, it could cause attenuation
of signals in the band being measured, preventing the
instrument from displaying accurate measured values.
