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.
Select the

range with the rotary switch.
Select the

function with the Mode button.
Please note, the unit defaults to

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. in both directions
