Click “Calibrate”, it will remind you to put away the calibration plate. Make sure the calibration plate is installed well on the instrument. Click “OK” or press measure button to start calibration.
When operating environment change (such as the rapid change of temperature, altitude and humidity), it must do calibration. In order to ensure the accuracy, please use the original standard plate for calibration. The dust on the standard plate will affect calibration accuracy. Please clean the standard plate and ensure it’s clean when calibrating.
The Standard plate is a precise optical component. Please avoid it from strong sunlight. Due to environment factors, the gloss value of standard plate will change over time. Therefore, it’s better to send it back to the factory or qualified local National Institute of Metrology for the calibration. (Once a year)

4 Routine Maintenance
(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 to use 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.
Attention：Forbid to use acetone solvent!
(3) In order to ensure the accuracy of the instrument, it is better send it back to 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 2.2.2 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 manufacturer (suggest once a year). Do not use cleaning tools to clean the internal instrument. Otherwise it will cause irreversible damage.
