Note: the specifications are valid for waveforms with fundamental frequency between 45 Hz and 70 Hz and
crest factor < 3.

Frequency
Hz 10 - 500 Hz
Note: The instrument is designed to measure power supply voltage and current signals in the range of 45 –
70 Hz and observes them as first harmonic. If the measured signal has frequency is greater than 70 Hz, the
instrument will understand it as a higher harmonic.
Note: Frequency is measured at voltages higher than 15% of range or 0.3 V (whichever is higher). Manually
change range to lower one if the instrument doesn't display the frequency while the signal is higher than 0.3
V.
