UNI-T UT10A User Manual

E. Measuring Diodes & Continuity (see figure 3 with dotted line)
Warning
To avoid damage to the Meter or to the equipment under test, disconnect
circuit power and discharge all high-voltage capacitors before measuring
diodes and continuity.
Never attempt to input over 60V in DC or 30V rms in AC to avoid personal
dangerous.

Testing Diodes
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.
To test out a diode out of a circuit, connect the Meter as follows:
1. Set the rotary switch to Ω range.
