Measurement instructions Precautions before operation: 1. Turn on the power and check whether the battery is under voltage. If " " is displayed on the screen, you need to replace the battery before operation. If not, please follow the steps below. 2. The " " warning symbol next to the jack of the measurement probe indicates that the input voltage or current should not exceed the indicated value, which is to protect the internal circuit of the instrument from damage. 3.
3. Press " " key to switch frequency and duty ratio, and long press it to turn on or turn off VFD function. Attention： 1. Before turning the function rotary switch, leave the measurement probe from the circuit under measurement. 2. When the screen only displays "OL", it means that the range has been exceeded and the measurement should be terminated. 3. Do not input AC voltage with effective value higher than 600V, otherwise there is a risk of damaging the instrument. 4.
1. Insert the red probe into the " into the " jack and the black probe jack. 2. Turn the knob switch to the " " position, and connect the probe to the power supply or load to be measured. The polarity and measured value of the contact terminal of the red probe will be displayed on the screen. 3. Press the key to switch DC voltage, AC voltage and frequency measurement. Attention： 1. Before turning the function rotary switch, leave the measurement probe from the circuit under measurement. 2.
2. When the screen only displays "OL", it means that the range has been exceeded and the measurement should be terminated. 3. Do not input AC voltage with effective value higher than 600V, otherwise there is a risk of damaging the instrument. 4. When measuring large capacitance, discharge the capacitance before measuring. Non-contact electricity verification (NCV) / Live wire detection (Live) 1. Turn the knob switch to the " " position and press the key to switch NCV or Live function. 2.
NCV Live Warning： 1. Measurement range: about 36V~600V, 50Hz or 60Hz. 2. When using, even if there is no sound or display prompt, the wire to be measured may still have voltage. The instrument may be affected by other factors (such as shielded wires and cables, thickness of insulation layer, distance from voltage source, diversity in socket design, etc.), and fail to sense the electric field. 3.
Warning： 1. Before turning the function rotary switch, leave the measurement probe from the circuit under measurement. 2. Do not input a voltage with an effective value higher than 0V, otherwise there is a risk of damaging the instrument. uA current 1. Insert the red probe into the " " jack and the black probe into the jack. 2. Turn the knob switch to the " " position and press the key to switch the AC current, DC current or frequency measurement. 3.
3. Connect the measurement probe in series to the load, and the polarity of the red probe connection will be displayed when the current value is displayed. Warning： 1. Before turning the function rotary switch, leave the measurement probe from the circuit under measurement. 2. When the screen only displays "OL", it means that the range has been exceeded and a higher gear range should be switched for measurement. 3.
