3.3 MEASURING RESISTANCE
1.
Connect the black test lead to the COM jack and the red test lead to the V/
Ω
jack. (The polarity of
red lead is “+” )
2.
Set the rotary switch at desired Q position and connect test leads across the resistor under
measurement.
NOTE
1.
If the resistance being measured exceeds the maximum value of the range selected or the input is
not connected, an overrange indication “1” will be displayed.
2.
When checking in-circuit resistance, be sure the circuit under test has all power removed and that all
capacitors have been fully discharged .
3.
For measuring resistances above 1M
Ω
the meter may take a few seconds to stabilise. This is normal
for high resistance measurements.
