11.8 Measuring resistance

Make sure that all objects that you wish to measure (including cir-
cuit components, circuits and component parts) are disconnected
and discharged.
Follow the steps below to measure the resistance:
Turn on the multimeter and select

the "Ω" measurement mode.
Insert the red test lead into the Ω

measurement socket, the black
test lead into the COM measure-
ment socket.
Check the test leads for continuity

by connecting both test probes to
one another. The multimeter should
then show a resistance value of ap-
prox 0–0.5 Ω (inherent resistance
of the test leads).
For low-impedance measurements

of <600 Ω, press the F3 "REL" but-
ton when the measuring probes are
short-circuited. This ensures that
the inherent resistance of the test leads does not affect the resistance measure-
ment. The display should show 0 Ω.
Connect the test probes to the object that you want to measure. The measure-

ment value will be indicated on the display (provided that the object you are
measuring is not highly resistive or disconnected). Wait until the display stabi-
lises. This may take a few seconds for resistances greater than 1 MΩ.
"OL" (overload) indicates that the measurement range has been exceeded or

that the circuit is broken.
After measuring, remove the test leads from the measured object and turn the

multimeter off.
