4.4.5. Resistance measurement and Continuity test
CAUTION
Before attempting any resistance measurement, cut off power supply from
the circuit to be measured and make sure that all capacitors are discharged,
if present.
Fig. 6: Use of the instrument for resistance measurement and continuity test
1. Select the

position. The symbol “M
” is shown on the display
2. Use the RANGE key for manually selecting the measuring range (see § 4.2.4) or use
Autorange selection. If the value of resistance is unknown, select the highest range
3. Insert the red cable into input lead HzV

and the black cable into input lead COM
4. Position the test leads in the desired points of the circuit to be measured (see Fig. 6).
The display shows the value of resistance
5. If the display shows the message “OL”, select a higher range.
6. Press the MODE key to select the Continuity test. The symbol “
” is shown on the
display. Insert the red and black cables as instructed for resistance measurement. The
buzzer activates for resistance values <30

7. For using the HOLD function see § 4.2.1, for measuring MAX/MIN/AVG values see
§ 4.3.1 and for saving the result see § 4.3.5
