Safety precautions

Before using the device, please read the safety precautions and follow the operating instructions. Failure to follow the relevant operating instructions may weaken or lose the protective ability provided by the device to you.

1. Before use, the multimeter and probe should be checked to prevent any damage or abnormal phenomena. If it is found that the insulation of the probe and housing has been significantly damaged, and the LCD display is not displaying, or if you believe that the device is no longer functioning properly, do not continue to use it.
2. It is strictly prohibited to use the device until the back cover and battery cover are properly covered to prevent the risk of electric shock and endangering one’s own safety.
3. When conducting measurements, the fingers holding the pen should not exceed the position where the pen stops, and should not touch exposed wires, connectors, unused input terminals, or the circuit being measured to prevent electric shock.
4. Before measurement, the function switch must be placed in the correct position, and shifting gears during measurement is strictly prohibited to prevent damage to the device.
5. Do not apply an AC/DC voltage greater than 600V between the device terminal and ground to prevent electric shock and damage to the device .
6. When the measured DC voltage is higher than 60V or AC voltage is higher than 30Vrms, the device should be used with caution to prevent electric shock.
