DC Voltage
Range Resolution Accuracy
400mV 0.1mV ± (1.0% of rdg + 2 digits)
4V 0.001V
± (0.7% of rdg + 2 digits) 40V 0.01V
400V 0.1V
600V 1V ± (0.8% of rdg + 2 digits)
• Input impedance: 10MΩ.
• Max. input voltage: 1000V DC.
• 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 the circuit, the true reading
will be shown.
