Safety Instructions This meter conforms to the IEC61010-1 international electrical safety standard. The design and manufacture of instruments shall strictly comply with IEC61010-1 CATIII 600V safety standard and pollution level 2. Safety Operation WARNING To avoid possible electric shock or personal injury and other safety accidents, please abide by the following specifications: ● Please read this manual carefully before using the instrument.
● Do not work alone so that you can get help in an emergency. ● To avoid electric shock or injury due to wrong reading, please replace the batteries in time when the indicator “ ”is displayed. ● Do not use the instrument around explosive gas or steam or in a humid environment. ● When using the probe, hold your finger behind the probe finger guard.
Suitable for testing and measuring circuits CAT connected to the distribution part of low voltage III power supply devices in buildings. Install The Battery Or Fuse Install Battery ① Remove the rubber sleeve on the outside of the multimeter. ② Remove the screw that secures the battery cover and remove the battery cover. ③ When installing the batteries, please pay attention to the polarity of the battery. After the installation is successful, you will hear a “beep” sound.
WARNING ● In order to avoid electric shock or personal injury caused by inaccurate reading, please replace batteries immediately when the battery power is low. ● Do not discharge the battery by shorting it or reversing its polarity. ● In order to ensure the safe operation and maintenance of the meter, please take out the battery when it is not used for a long time. Replace Fuse If the fuse is blown out, “ ” and “ ” will be displayed on the screen and there will be a continuous beeping sound.

measurement. “ ” will be displayed. 2) Insert the red probe into the “ ” jack and the black probe into the “COM” jack. 3) Touch the test lead tips together to check if they are connected normally. The indicator light should turn green and the buzzer sound. 4) Connect the probe with the voltage source or resistor in parallel for measurement. The meter will automatically recognize the currently measured signal. Start Testing 4.
③ When the resistance is greater than 50Ω, it will automatically jump to resistance measurement. ④ If the measured value is equal to the nominal resistance of the resistor or within the range of error, the resistor is functioning correctly. If there is a large deviation between the nominal resistance and the measured resistance, the resistor is bad. If the measured resistance is infinite (open circuit), zero (short circuit), or unstable, it means the resistor is damaged and can no longer be used.
DC/AC mV Measurement 1) Long press “ ” key to turn on the power. 2) Insert the red probe into the “ ” jack and the black probe into the “COM” jack. 3) Touch the test lead tips together to check if they are connected normally. The indicator light should turn green and the buzzer sounds. 4) Press “ ” key to switch to “ ” function. Press ” ” to switch between AC voltage and DC voltage.
Frequency/Duty Measurement 1) Long press “ ” key to turn on the power. 2) Insert the red probe into the “ ” jack and the black probe into the “COM” jack. 3) Touch the test lead tips together to check if they are connected normally. The indicator light should turn green and the buzzer sounds. 4) Press “ ” key to switch to “ ” function. 5) Connect the probe with voltage source or both ends of load in parallel for measurement. 6) After the reading stabilizes, record the reading from the screen.
3) Touch the test lead tips together to check if they are connected normally. The indicator light should turn green and the buzzer sounds. 4) Press “ ” key to switch to “ ” function. 5) Connect the probe with both ends of the capacitor in parallel for measurement. 6) After the reading stabilizes, record the reading from the screen. 7) When the measurement is completed, disconnect the test leads from the measured object.
to the opposite ends of the diode and measure again. 6) After the reading stabilizes, record the reading from the screen. 7) When the measurement is completed, disconnect the test leads from the measured object. WARNING To avoid damage to the meter and/ or the measured object, disconnect the circuit power and discharge all the high-voltage capacitors before testing. Note: ① The displayed value is an approximation of diode forward voltage drop. The forward voltage drop of the diode is generally 0.3V-0.8V.
6) After the reading stabilizes, record the reading from the screen. When measuring AC current, the frequency is displayed at the same time. 7) When the measurement is completed, disconnect the test leads from the measured object. WARNING 1. Pay special attention to safety when measuring high voltage to prevent safety hazard. 2.Before use, test on known current to confirm intact function. Caution: The measured current should not exceed the rated maximum current of 600mA to prevent safety hazard.
Live Test 1) Long press “ ” key to turn on the power, press “ ”key to switch to “ ” function. Then press “ ” key to switch to live function, the meter shows “Live”. 2) The "COM" jack should remain empty. Insert the red probe into the “ ” jack, then contact the probe the test point. 3) If the meter detects weak AC voltage, the green indicator lights up, the buzzer beeps slowly, displaying “--- L”.

Clean If there is dust or humidity on the jack, it may cause measurement error. Clean the instrument as follows: 1) Turn off the meter power and remove the test probes. 2) Wipe the case with a damp cloth or mild detergent. Do not use abrasives or solvents. Wipe the contacts in each input jack with a clean cotton swab soaked in alcohol. WARNING Please keep the inside of the meter clean and dry at all times to prevent electric shock or damage to the instrument.
