4.3.6. Resistance measurement
CAUTION
Before taking resistance measurements in circuit remove power from the
circuit being tested and discharge all capacitors.
Fig. 7: Resistance measurement
1. Turn the selector on .
2. Insert the test leads into the jacks, the red plug into HzVA jack and the black
plug into COM jack (Fig. 7).
3. Connect the red and black test leads to the circuit under test, the resistance value will
be displayed with automatic detection of the range.
4. Press RANGE key to activate the manual mode; the “AUTO” symbol disappears from
display. Press cyclically RANGE to change the position of the decimal point on the
display. To activate the Autorange function keep pressed RANGE for at least 1 second.
5. The message "OL" means that the resistance exceeds the measuring limits. In this
case disconnect the test leads from the circuit under test to avoid damaging the
instrument or endanger your own safety.
6. For minimum and maximum value measurement and HOLD function please refer to
paragraph 4.2.
