Meter Functions – Resistance (Ω)
IMPORTANT: If you are testing an application that has capacitors in the
circuit, be sure to turn the power OFF on the test circuit and discharge all
capacitors. Accurate measurement is not possible if external or residual
voltage is present.

Touch the Black test probe to the negative (-) side of the diode.
Touch the Red test probe to the positive (+) side of the diode. Reverse the probes: Black to
the positive
(+) side and Red to the negative (-) side.
Note:
A "good" diode will read low in one `direction and high in the other direction when the
probes are reversed (or vice versa).
A defective diode will have the same reading in both directions or read between 1.0 to 3.0 V.
