Connect the black test lead to the COm terminal and the red test lead to the
5.7.2.
Set the function switch to the Ω position.
5.7.3.
Connect the test leads across the object to be tested.
5.7.4.
Read the reading on the display.
Note:
(i) If the resistance is more than 1MΩ it may take several seconds for the reading to stabilise. This is normal for high resistance
measurements.
(ii) If the input terminals are in an open circuit state, the over range indicator "ol" will be shown on the display.
(iii) Before measurement, disconnect all power to the circuit to be tested and discharge all capacitors thoroughly.
