CAUTION
The maximum input for AC voltage is 600V. Don’t try to measure higher
voltages to avoid risks of electrical shocks or serious damages to the
instrument.

1. Turn the selector on .
2. Insert the black test lead in the COM jack and the
red probe in the V+/Ω jack (Fig. 4).
3. Connect the red probe and the black test lead to
the poles of the circuit under test; the voltage
value will be displayed (automatic range
detection).
4. Should you get the message "
O.L
" it means that
the detected voltage exceeds the limits which the
instrument can measure. In this case stop the
measurement by disconnecting the test leads
from the circuit under test to avoid risks for
yourself and for the instrument.
5. If you want to activate the HOLD, REL and
RANGE functions refer to chapter 4.2.
