14. Diode and Continuity Testing
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1. Connect the red test lead to "VmA" jack and the black one to the
"COM" jack (the red lead has a positive polarity "+".).
2. Set the rotary switch in the "
3. Press "SELECT" and choose the "diode" or "continuity" measurement
mode.
4. Connect the red test lead to the anode of the diode to be tested and
the black test lead to the cathode of the diode. If the resistance is
lower than approximately 30 Ω, the buzzer sound.
5. If the diode or continuity being measured is connected to a circuit, turn
off the power and discharge all capacitors before applying the test
probes.
15. Frequency and Duty Cycle Measurement
Do not conduct frequency or duty cycle measurements on live
circuits. Make sure all capacitors in the circuit are depleted.
1. Connect the red test lead to the "VmA" jack and the black test lead to
the "COM" jack.
2. Set the rotary switch in the "Hz" position.
3. Press "Hz%" and choose the "frequency" or "duty cycle" measurement
mode.
4. Connect the test leads to the source to be measured and read the LCD
display.

16. Temperature Measurement

1. Connect the red banana plug to "
2. Set the rotary switch in the "°C" position.
3. Put the probe into the field to be measured and read the LCD display.
