5.8 Diode Test (CLASSIC mode)
Warning: Do not perform diode tests before removing the power to the diode or other
devices under test during a measurement. Injury to persons can occur.
1. If not already selected, choose CLASSIC Diode test mode in the Programming
Menu (See Section 5.10.2).
2. Set the function switch to the diode position.
3. Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive Ω terminal.
4. Use the MODE button to select the diode test function. The diode indicator
will be displayed.
5. Touch the tips of the probe across the diode or semiconductor junction under
test.
6. For Classic Diode mode: If the reading is between 0.40 and 0.80V in one
direction and OL (overload) in the opposite direction, the component is good. If
the measurement is 0V in both directions (shorted) or OL in both directions
(open), the component is bad.
