1. Turn the selector on Ω.
2. Insert the black test lead in the COM jack and the
red probe in the V+/Ω jack (Fig. 6).
3. Connect the test lead to the circuit under test; the
resistance 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.
