3.2.1 DC Voltage

- Input Impedance 10MW

- Overload protection

40mV~400mV range 250V DC or rms AC,

4V-1000V ranges 1000V DC or 750V rms AC.

- Max. input voltage 1000V DC or 750V rms AC

NOTE

At small voltage range, unsteady readings will appear before the test leads contact the circuit. This is normal because the meter is highly sensitive. When the test leads contact

he circuit, the true reading will be shown.
