F. CAPACITANCE MEASUREMENT
(see figure 6)
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.
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. Insert the red test lead into the
ºC terminal and the black test lead into the
COM
terminal.
2. Set the rotary switch to
.
3. Connect the test leads across with the object being measured.
The buzzer sounds if the resistance of a circuit under test is less than 70
Ω.
The LCD displays the resistance value of a circuit under test.

Note
• The LCD display “1” indicating the circuit being tested is open.
• When continuity testing has been completed, disconnect the connection between the testing
leads and the circuit under test.
