4.4. MEASUREMENTS - DESCRIPTION
4.4.1. DC voltage measurement

CAUTION

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

Fig. 3: DC voltage measurement

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. 3).

3. Connect the red probe and the black test lead

respectively to the positive and negative 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. Should you get a symbol "-" it means that the

detected voltage has an opposite direction
compared to the connection shown in Fig. 3.

6. If you want to activate the HOLD, REL and

RANGE functions refer to chapter 4.2.
