How much do you know about a little knowledge of a luminance meter calibration device? Let's follow the editor of Luminance meter supplier china to have a simple understanding!

A calibration device for a luminance meter, comprising a dial, a support frame for supporting the dial, and two level gauge connectors. The dial includes a body. The body is provided with at least two scale lines with an angle of 45° and two level gauge connectors. It is set on the support frame and can be moved relative to the support frame to adjust the two level meter connectors to respectively align the two scale lines with an angle of 45°. Through the above-mentioned brightness meter calibration device, the two level meters can be connected to two respectively Level meter connector, and by adjusting the position of the level meter connector on the support frame, the two level meter connectors can be aligned with the two scale lines with an angle of 45°, and then the light emitted by the two level meters can be aligned with the standard. The lamp and the brightness meter to be tested can accurately control the standard lamp to a 45° angle on the brightness meter to be tested, and at the same time, through the horizontal line function of the level meter, the standard lamp and the brightness meter to be tested can be kept at the same level, which can ensure the calibration of the brightness meter. The accuracy is high.
The above is the editor of Luminance meter supplier china: a brief introduction to the little knowledge about the calibration device of the luminance meter.
