Precautions for the use of explosion-proof electronic scales:

First determine the hazardous medium and the area in which it is used; determine the type, category, level and temperature group of the explosion-proof electronic scale in sequence; gas explosion-proof and dust explosion-proof are completely different; coal mine explosion-proof and conventional explosion-proof are completely different; explosion-proof The installation and use of electronic scales must be carried out in strict accordance with construction specifications.

Precautions for the use of explosion-proof batteries:

As long as the power cord is connected to AC 220V, the battery will be charged. Therefore, if the battery is not used frequently, remove the battery.

In order to avoid overheating in the machine and overcharging the battery, current limit is imposed. If the user feels that the charging is too slow, please purchase a charger and charge the battery outside the machine. Please note that the wire connecting the battery cannot be reversed (the red wire is +, the black wire is -), otherwise the built-in battery of the instrument will be burnt out. Be sure to fully charge before use!

When the meter is powered by batteries, once the AC power is connected, the meter will automatically switch to using AC power, and the AC indicator will be on. There is a battery power indicator in the lower left corner of the meter screen. After the last battery indicator light goes out, the meter will automatically cut off the DC power supply and the meter will stop working. Please charge it immediately.

When in use, please charge the battery for about 10 to 16 hours, so as not to mistake it for a fault due to the low voltage caused by the self-discharge of the battery.

In normal use, you should pay attention to charging the battery, each time about 10-16 hours. If it is not used for a long time, it should be noted that the meter should be energized for 10-16 hours every 2 months to extend the service life of the battery.
