The battery inside the instrument is a special lithium battery. In order to give full play to the performance of the battery,
please use the internal battery power supply when you start using the instrument. The first use of the battery needs to be
depleted, and then charging the battery, the first charging time should be no less than 10 hours. Battery charging
temperature range is 0°C~50°C. For your safety, the charge will terminate automatically when the charging temperature is
too high. When the instrument is idle for more than two months, it should be charged in time to maintain the battery power.
Please don't take out the battery without permission. Please do not let the battery close to the fire source or strong heat.
The battery should be removed when the instrument is stored for a long time. The storage temperature range of the
battery is -20°C~45°C.
Instrument screen cleaning and touch calibration
The display of the instrument is a 5.8 inch color LCD with touch screen. Please do not use sharp objects to click on the
screen, otherwise it may lead to damage to the LCD screen. You can clean the LCD screen using soft fabric, but do not
use organic solvent.
Instrument calibration
It is recommended that the instrument be calibrated once every two years. Please contact the supplier for specific items.
