1) The gloss meter is a precise instrument. Please operate and store it in

standard laboratory environment (Temperature: 20 ℃ ， Standard

atmospheric pressure, Humidity: 50~70%RH). Please avoid using it in

humid environment, strong electromagnetic interface environment, high

light intensity environment and dusty environment.

2) Standard plate is a precise optical component. Avoid being damaged by

sharp object, avoid dirtying the board and avoid exposing it to sun.

Regularly clean the standard plate by using soft cloth with alcohol in one

direction. Ensure there are no tiny particles or sundries on the soft cloth.

Before calibrating, clean the standard plate to make accurate calibration.

the factory or qualified Local National Institute of Metrology for calibration.

(Once a year)

4) It needs to modify calibration value when the calibration value is different

from practical measurement value. View chapter 2.2 for details.

5) The gloss meter is powered by built-in battery. When long time not using

this instrument, please charge it biweekly in order to protect the battery and

extend the battery life.

6) The internal clean work of the instrument should be finished by
