Resistance Testing
WARNING
To avoid damaging the multimeter or
the object being measured, ALWAYS
disconnect the circuit power and
discharge all high-voltage capacitors
before measuring resistance.
1. Insert the black lead into the COM
terminal, and the red test lead in to the
terminal. [Figure 1.1]
2. Turn the rotary dial to .
3. Connect the test leads to the object being
measured. Hold them in place until the
readings on the display stabilize.
Note:
• The LCD will read “ “ if there is an
open-circuit for the tested resistor or
if the resistor value is higher than the
maximum range of the multimeter.
• When testing high-resistance objects, it is
normal to wait for several seconds before
receiving a stable reading (>1MΩ). To
obtain a stable reading, use the test leads
for the shortest time possible.
• If the resistance reading with the
connected test leads is not
≤
0.5Ω, check
if the leads are loose or damaged.
• The maximum resistance rating for the
multimeter is 200MΩ.
