Precautions:
1. Avoid direct light during use, otherwise the measurement accuracy will be affected.
2. The standard board of the instrument should be kept clean. Do not touch the surface with your fingers. If the surface is stained, it will lead to increased instrument error and inaccurate reading
Wipe with head paper or anhydrous ethanol.
3. Because of the high stability of the instrument, the instrument does not need to be calibrated frequently, it is recommended to re-calibrate once after continuous use for 2 giờ.
4, the battery should be replaced in time, otherwise long-term storage, the old battery may flow out of waste liquid, causing damage to the instrument.
