III.Packing List
1. Moisture-proof
In humid climate areas or seasons, if the instrument is not used for a long time, it is advisable to turn it on and power it up once a month (about two hours) to dissipate moisture and protect the components.
2. Storage
When not in use, the instrument should be stored in an indoor environment with a temperature of -20～60℃ and a relative humidity below 85%, with ventilation and no corrosive gases.
3. Prevent exposure to direct sunlight
When using it outdoors, operate it in a shaded area as much as possible to avoid or reduce direct exposure of the display screen to sunlight.
4. Charging
The instrument uses a lithium battery as its power supply. If the battery is low, please use the included charger to charge it. Charging time is generally 2 to 4 hours. Charging is not allowed when the instrument is on, and must be done when the instrument is turned off. When charging, the charger indicator light will turn red, and it will turn green when charging is complete. Please use the charger included with the instrument.
