DANGER
Never apply voltage to the test leads when the
Diode Check functions is selected. Doing so
may damage the product and result in personal
injury.
To avoid electrical accidents, remove power
from the circuit before measuring.
3.3 Diode Check
A good diode allows current to flow in one direction
only. To test a diode, turn the power off, remove the
diode from the circuit, and proceed as follows:
(1) Set the rotary switch to "
" position.
(2) Connect the black test lead to "COM" terminal
and red test lead to "
" terminal.
(3) Touch the red lead to the positive side of the
diode and the black lead to the negative side.
The meter can display diode voltage to
approximately 1.999 V.
A typical voltage is 0.3 to 0.8 V.
