Frequency lter it is inserted in the frequency measurement circuit and may aect frequency measurement. It
can be used for ltering high-frequency components of interference to make the measured frequency
parameter more accurate. When the frequency lter is switched on, the voltage or current of no more
than 200Hz can be measured. The cuto frequency is 500HZ.
Line lter it is inserted in the voltage and current measurement circuit and has direct inuence on measurement
of the voltage, current and power. When the line lter is switched on, noise and high-frequency
components from the inverter or distortion waveform can be ltered. The cuto frequency is 500HZ.
2.2.3.2 Crest factor
The crest factor is the ratio of the waveform peak to the eective value. The Measurement Conditions crest
factor of 5335B is specied as the times of the crest value which can be input under the rated input conditions.
The crest factor CF3 or CF6 can be selected in the interface “Menu > SETUP > OTHER SET”. See Chapter 4
for more details.
