For voltage mV scale, the input range is about 100mVrms-30Vrms, duty ratio is 1.0%-99.0%, which is only
suitable for ≤1kHz square wave measurement.
For voltage V scale:
When the input frequency band is ≤50kHz, the input amplitude is >5Vrms;
When the input frequency band is >50kHz~100kHz, the input amplitude is >10Vrms;
The input range of 1000V scale needs to be ≥100V; Duty ratio is 10.0%-90.0% which is only suitable for
50Hz or 60Hz;
For current measurement scale, the input range of frequency/duty ratio measurement is 60% of the full range.
