Place the function dial at the VDC (range: 600mV, 6V, 60V, 600V, 1000V) position; 2. Insert the black test lead into the negative COM port and the red test lead into the positive V port; 3. Touch the tip of the test lead to the test object to ensure that the electrode is correct (red connects the positive electrode, and black connects the negative electrode); 4. Read the voltage value on the display. When it is greater than 30V, the LCD will display a high voltage danger symbol. When it is greater than 1000V, the buzzer will sound. The red light is always on. If the electrode is reversed, a minus sign will be displayed before the value. AC Voltage Measurement: Warning: Please observe all safety precautions when measuring on wires with wires. Note: Do not perform measurement at the moment when the power is turned on or off, as high voltage may damage the meter. 1. Set the function dial to VAC/HZ (range: 6V, 60V, 600V, 1000V); 2. Insert the black test lead into the negative COM port and the red test lead into the positive/port; 3. Touch the tip of the test lead to the test object; 4. Read the voltage value on the display. When it is greater than 30V, the LCD will display a high voltage danger symbol. When it is greater than 1000V, the buzzer will sound and the red light will be on; 5. Short press the MODE button to enter the AC voltage frequency measurement mode, the measurement range is 45Hz~1KHz. DC Current Measurement: Note: The measurement time cannot exceed 10 seconds under the condition of 20A, otherwise the meter or test leads may be damaged. During the measurement, if the current cannot be estimated, the measurement should be started from the high range, and if necessary, the low range should be selected. 1. Insert the black test lead into the negative COM port; 2. Measure the current below 600mA DC, set the function dial to DC 60uA or mA (range: 60mA, 600mA), and insert the red test lead into the mA port; 3. When measuring DC 20A, set the function dial to the 20A gear and insert the red test lead into the 20A port; 4. Disconnect the power supply of the tested circuit, touch the black test lead to the negative pole of the tested circuit, and the red test lead to the positive pole of the tested circuit; 5. Turn on the power supply; 6. Read the current value on the display. When it is greater than 10A, the buzzer will sound and the red light will stay on. AC Current Measurement: Warning: To prevent electric shock, do not measure on a circuit with a voltage exceeding 250V. Note: The measurement time cannot exceed 10 seconds under the condition of 20A, otherwise the meter or test leads may be damaged. During the measurement, if the current cannot be estimated, the measurement should be started from the high range, and if necessary, the low range should be selected. 1. Insert the black test lead into the negative COM port; 2. When measuring 600mA, put the function keyboard in the AC 60mA, 600mA gear position, and insert the red test lead into the mA port; 3. When measuring 20A,
