That will damage the items.and even may cause the re or an electric

shock.

Other power supply will damage to the product,and even may cause

the re or an electric shock.

The calibration should be carried out under a standard calibration
condition, such as the standard gauge must be accuracy 3 times of
HS108, ambient temperature (20±2)℃.

Don't immersed in water or exposed to water or getting wet

Only use the special charger or battery

The calibration should be carried out under a standard calibration condition
