6.5. Resistance Measurement
CAUTION!
Making resistance measurements on idle circuits or components and
discharge all capacitors present in the circuit.
1.
Connect the black test lead to the COM jack and the red test lead
to the V/Ω/-mA- jack. (Note: The polarity of the red test lead is "+")
Set the function switch to the Ω range to be used and connect the
2.
test leads across the resistance under measurement.
Note:
1.
If the resistance value being measured exceeds the maximum
voltage of the range selected, an over-range indication will be
displayed "OL". Select a higher range. For resistance approx. 1
MΩ and above, the meter may take a few seconds to stabilize.
This is normal for high resistance readings.
2.
When the input is not connected, i. e. at open circuit, the
figure "OL" will be displayed for the overrange condition.
3.
When checking in-circuit resistance, be sure the circuit under test
has all power removed and that all capacitors are fully discharged.
