other ranges:10MΩ;
The frequency response of sine wave and triangular wave is 40Hz-1kHz; the frequency response of other waveform is 40Hz-200Hz.
Over-range protection：
200mV range: DC 250V or AC peak value.
Other ranges: DC 1000V or AC peak value
Displaying: True RMS (true value response)
It’s normal that some range does not turn to “0” and it does not affect the measuring accuracy.
