I. Cleaning Methods
1. Daily Cleaning: Gently wipe the surface with a soft, dry cloth. For stains, you can use a mild detergent, but avoid getting liquid inside the device. Carefully clean the sensor with cotton swabs; do not touch it with sharp objects.
2. Deep Cleaning: For waterproof models, rinse with cooled boiled water; for non-waterproof models, disinfect with 75% alcohol swabs. Avoid using corrosive cleaners and do not soak in water.
II. Maintenance Tips
1. Regular Calibration: It is recommended to calibrate every six months to one year using professional equipment or by comparing with other calibrated instruments. Operate in a stable environment and avoid frequent switching.
2. Storage Environment: Store in a dry, cool place, away from direct sunlight and moisture. If not used for a long time, store in a sealed bag.
3. Battery Check: Check the battery regularly; replace it promptly if the power is low to prevent affecting use.
4. Avoid Interference
Keep away from strong magnetic fields, high temperatures and humidity, and avoid dropping or bumping.
III. Precautions
Turn off the machine before cleaning. Do not use harsh cleaning agents.
Use qualified calibration solution for calibration to ensure accuracy.
Store in a dry place, protected from moisture.
