4.7. Resistance Measurements
WARNING! Be sure that the circuit under test has all power
removed and that any associated capacitors are fully discharged
before you make a resistance measurement.
1.
Connect the black test lead to the COM jack. (Note: The polarity
of the probe tip connection is positive "+").
2.
Set the function-switch at -range to be used and connect test
leads across the resistance under measurement.
Note:
*
For resistance above 2 M, the meter may take a few
seconds to stabilise reading. This is normal for high resistance
measuring.
*
When the input is not connected, i. e. at open circuit or
the value is greater than 20 M, the figure "OL"
displayed for the over range condition.
