In the process of measuring with a Metal gloss meter, the glossmeter calibration plate needs to be properly maintained and stored. Because the metal gloss meter measurement itself is a comparison method, that is, it is calibrated before the measurement (the gloss value of the comparison standard plate is 100), and then the object to be measured is tested by the comparison method. If the standard plate is found to be stained or scratched, the measurement result after calibration is definitely inaccurate. Let's talk about the maintenance and cleaning precautions of the standard plate of the metal gloss meter.

When is calibration required?

When the operating environment of the Metal gloss meter changes greatly, such as temperature, altitude, humidity, etc., the instrument needs to be recalibrated. Calibration is also required if the calibration validity period is exceeded. A new machine needs to be calibrated. Calibration is also required after the instrument is reconfigured with a new calibration plate. To ensure accurate calibration of the instrument, please use the standard plate provided by the original manufacturer or re-calibrated. The dust on the standard plate will affect the calibration effect. Before calibration, please wipe the working surface of the standard plate with a wiping cloth to confirm that the working surface is clean.
 
How to clean the standard plate of Metal gloss meter?

The calibration plate of the Metal gloss meter is used to measure the accuracy of the gloss. If the standard plate is inaccurate, the instrument is inaccurate. Moreover, the gloss of the standard board is easy to be stained. The standard board generally uses a special base, and the standard board is embedded in the base to avoid external pollution and scratches.
