The measurement is performed by capacitive coupling.
Selection of the MANUAL frequency range < 900 kHz (default) or > 900 kHz,
via a short pressing of the key opposite.
Selection of voltage range in MANUAL mode possible, via a long pressing of
the key opposite.
Input resistance:  10 M (Freq < 100 Hz)
Maximum permanent acceptable voltage: 1000 Vrms. See ().
Protection by varistors at the voltage input
You measure the frequency and value of a voltage or a current.
