•
Do not input voltages above 600 V. Although it is possible to measure
higher voltage, it may damage the meter.
•
Exercise caution to avoid electric shock when measuring high voltage.
When the measured voltage is ≥30 V (AC) or ≥60 V (DC), the LCD will
•
display the high voltage alarm prompt.
3. Resistance measurement (Picture 4)
3.1 Insert the red test lead into the
COM jack.
3.2 Switch the dial to the
resistance measurement Ω, and connect the test leads with both ends of
the measured resistance in parallel.
Note:
•
If the resistor measured is open or the resistance exceeds the maximum
range, the LCD will display "OL".
•
Before measuring the resistance online, switch off the circuit's power
supply, and fully discharge all capacitors to avoid inaccurate measurement.
If the resistance is not less than 0.5 Ω when the test leads are short-
•
circuited, check the test leads for looseness or other abnormalities.
•
To avoid personal injury, do not input voltages higher than 30 V.
4. Continuity test (Picture 4)
4.1 Insert the red test lead into the
COM jack.
4.2 Switch the dial to
continuity measurement
the measured load in parallel.
4.3 Resistance measured <10 Ω: The circuit is in good conduction status; the
buzzer beeps continuously. Resistance measured >31 Ω: The buzzer makes
no sound.
Note:
•
Before measuring the continuity online, switch the circuit's power supply
off and fully discharge all capacitors.
•
To avoid personal injury, do not input voltages higher than 30 V.
