- When measuring resistance above 1MΩ, it is normal to take a few seconds to stablize
reading.
- Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC 60V.
- Those voltages may pose shock hazard.
- After completing the measurement, disconnect the test leads from the circuit under test.
CONTINUITY TEST (PICTURE 4)
1) Insert the red test lead into the
2) Turn the function dial to
switch to continuity test, and connect the test leads with both ends of measured load in parallel.
3) When the measured resistance ≤30Ω: The circuit is in good conduction status; the buzzer
beeps continuously. When measured resistance ≥70Ω: there will be no buzzer sound.
Note:
- Before measuring the continuity online, switch off the power supply of the circuit, and fully
discharge all capacitors.
- Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC 60V.
- Those voltages may pose shock hazard.
- After completing the measurement, disconnect the test leads from the circuit under test.
DIODE TEST (PICTURE 4)
1) Insert the red test lead into the
polarity of the red test lead is "+" and that of the black test lead is "-".
2) Turn the function dial to the
diode test.
3) Connect the red probe with the diode anode, and black with the diode cathode.
4) Read the approximate forward voltage of the diode on the display. For silicon
PN junction, the normal value is generally about 500~800 mV.
Note:
- If the diode is open or its polarity is reversed, the LCD will display "OL".
- Before measuring the diode online, switch off the power supply of the circuit, and fully
discharge all capacitors.
- Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC 60V.
- Such voltage poses a shock hazard.
- After completing the measurement, disconnect the test leads from the circuit under test.
