AC measurement

Turn the knob switch (6) to the 400/600A~ / 40A~ / 4A~ position according to the current measurement limit (A~ appears on the screen). Press the trigger (4) to open the clamps (2) and fully enclose the conductor to be measured.
Then slowly release the trigger (4). To ensure measurement accuracy, the measured conductor must be placed in the center of the clamps. The measurement results will appear on the LCD (10).
If the measurement result is >3A, the orange backlight will turn on.
For the following measurements using test leads, turn the knob switch (6) to the appropriate position. Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (13).

AC/DC voltage measurement

Turn the knob switch (6) to the V~ (AC voltage) or V= (DC voltage) position. Press (7) until AC or DC voltage appears on the screen. Connect the probes to the measuring points. The measurement results will appear on the LCD (10).
If the measurement result is >80V, the orange backlight will turn on. The maximum measured voltage is 600V.

Resistance measurement

Turn the knob switch (6) to the position. Press (7) until MΩ appears on the screen. Connect the probes to the resistance measuring points of the circuit or resistor. The measurement results will appear on the LCD (10).
Before measurement, ensure the power supply is disconnected and the capacitor in the circuit is completely discharged.

Continuity test

Turn the knob switch (6) to the position. Press (7) until the symbol appears on the screen. Connect the probes to the circuit or component to be tested. The measurement results will appear on the LCD (10).
If the resistance is <30Ω, an acoustic signal will be emitted and the orange backlight will turn on.

Diode test

Turn the knob switch (6) to the position. Press (7) until the symbol appears on the screen. Connect the red test probe to the anode side and the black test probe to the cathode side of the diode to be measured.
The measurement results will appear on the LCD (10).
If the polarity of the test probes is reversed to the diode polarity, the OL (Overload) will appear on the screen. This can be used for distinguishing the anode and cathode sides of a diode.
