DC/AC Voltage Measurement

(see figure 3)

To avoid harms to you or damages to the Meter from eletric shock, do not
attempt to measure voltages higher than 600V AC/DC, although readings may
be obtained.

The DC Voltage ranges are:
400mV, 4V, 40V, 400V and 600V

The AC Voltage ranges are:
400mV, 4V, 40V, 400V and 600V
