E. Testing Diodes
(See figure 7)
Warning
To avoid possible damage to the Meter and to the
device under test, disconnect circuit power and
discharge all high-voltage capacitors before testing
diodes.
To avoid harms to you, please do not attempt to input
v o l t a g e s h i g h e r t h a n 6 0 V D C o r 3 0 V A C .
Use the diode test to check diodes, transistors, and
other semiconductor devices. The diode test sends a
current through the semiconductor junction, and then
measures the voltage drop across the junction. A good
silicon junction drops between 0.5V and 0.8V.
