1.Safety Precautions
Use the meter near the equipment with large electromagnetic interference, the reading of the meter will be unstable, and even may produce larger errors. Do not use when the appearance of the meter or test leads is damaged. If the instrument is not used correctly, the safety function provided by the instrument may be invalid. Extreme care must be taken when working around exposed conductors or busses. It is forbidden to use this instrument near explosive gas, steam or dust. The correct input terminal, function and range must be used for measurement. The input value must not exceed the input limit value specified in each range to prevent damage to the instrument. When the meter is connected to the line under test, do not touch the unused input terminals. When the measured voltage exceeds the rms value of 60V DC or 30V AC, be careful to prevent electric shock. When measuring with a test pen, place your finger behind the protective ring of the test pen. Before changing the range, make sure that the test pen has left the circuit under test. For all DC functions, in order to avoid the risk of electric shock due to possible incorrect readings, please use the AC function first to confirm whether there is any AC voltage. Then, select a DC voltage range that is equal to or greater than the AC voltage. Before performing resistance measurement or continuity test, the power supply of the circuit under test must be cut off, and all high-voltage capacitors in the circuit under test must be discharged. Do not measure resistance or conduct continuity tests on live circuits. Do not put it in an explosive and flammable place when not in use. When repairing TV sets or measuring power conversion circuits, be careful of high-amplitude voltage pulses in the circuit under test to avoid damage to the meter.

This product uses 3.7V/1000mA lithium battery for power supply, and the battery must be correctly installed in the battery box of the instrument. When the battery undervoltage symbol appears, please charge it in time. A low battery can cause the meter to read incorrectly, which could result in electric shock or personal injury. In the measurement category, the voltage measurement should not exceed 1000V. The case of the instrument (or part of the case | do not use the instrument when it is removed).
2. Safety Maintenance Habits
When opening the case of the instrument or removing the battery cover, the test pen should be pulled out first. When repairing the instrument, be sure to use the designated replacement parts. Before turning on the instrument, you must disconnect all related power sources, and you must also ensure that you do not have static electricity to prevent damage to the components of the instrument. The calibration and maintenance of the instrument can only be returned to the factory for maintenance. When opening the case of the meter, it must be noted that some capacitors in the meter still hold dangerous voltages even after the meter is powered off. If any abnormality is observed in the instrument, the instrument should be stopped immediately and sent for repair. And make sure that it cannot be used until it passes the inspection. When not in use for a long time, and avoid storing in places with high temperature and high humidity.
3. Input protection measures
When performing voltage measurement, the maximum input voltage that can withstand is DC voltage 1000V or AC Voltage 1000V. Can withstand no more than 250V AC voltage or equivalent effective value voltage.

çAutomatic measurement
Note
Do not measure any voltage higher than 1000V DC/1000V AC to prevent electric shock or damage to the instrument. Do not apply more than 1000V DC voltage/1000V AC voltage between the common terminal and the ground to avoid electric shock or damage to the instrument.
In automatic mode, AC and DC voltage, resistance and continuity can be automatically measured. 1. After power on, it will automatically switch to "AUTO" automatic measurement mode. 2. Connect the black test lead and the red test lead to the COM input jack and the INPUT input jack respectively. 3. Use the test pen to measure the voltage value, resistance value and short-circuit point of the circuit to be tested at both ends. (parallel to the circuit under test) 4. At this time, the liquid crystal display will display the corresponding measured voltage value and resistance value at the same time. When measuring DC voltage, the display will show the voltage polarity connected to the red test lead at the same time. If the measured resistance value is less than 50, the buzzer will issue an alarm sound.
Notice
When the measured DC voltage is less than 0.75V and the AC voltage is less than 0.75V, the displayed resistance value may appear, because the minimum measurement voltage value of this product is 0.75V, and the minimum AC voltage is 0.75V.
1. When measuring low resistance, in order to measure accurately, please first short-circuit the two test leads to read the short-circuit resistance value of the test leads, and subtract the resistance value after measuring the measured resistance.
