Note:
[1] Please do not use in the following environments: places where temperature and humidity changes too much; places where vibration is very strong, places where corrosive oxygen or dust exists; places where water, oil, and chemicals splash; easy to explode and flammable gas.
[2] Before connecting the power supply, please make sure whether the voltage is within the rated range and whether the wiring terminals are positive Yes, otherwise it may cause serious damage to the instrument.
[3] The input wire should not be too long, it is better to use shielded wire.
[4] Keep the wiring junction away from high-voltage, high-current power supply lines to avoid interference, please confirm that the wiring is connected to the correct terminal.
[5] Before use, the meter needs to be energized and preheated for 15 minutes; the suitable use environment temperature is 0~50°C.
[6] Please note that the shell of the body will be corroded by organic solvents, strong acids and alkalis.
