That is, when the last shutdown was a manual shutdown, the next boot will be automatically calibrated; When the last power off is 5 minutes after the screen is turned off, it will not be automatically calibrated the next time it is turned on.

When the environment in which the instrument is used changes (such as drastic changes in temperature, altitude, humidity, etc.), the instrumentBe sure to calibrate. To ensure accurate calibration, use the standard plate supplied by the factory. The dust on the standard board will affect the calibration effect, before calibration, please wipe the working surface of the standard board with a wiping cloth to confirm that the working surface is clean. The standard board is a precision optical component, which should be avoided from exposure to light and should be properly stored. Due to environmental factors, the photometric data of the standard can change over time. Therefore, we recommend that you regularly return the standard board to the original factory or a qualified metrology institute for calibration testing (preferably once a year).

Note:

1. The calibration plate that each instrument has, such as using other calibration plates or other objects as calibration plates, that isSo that by calibration, the measurement is also inaccurate. Therefore, before calibration, you should check the SN code of the instrument and the SN code of the calibration boardNo, there are SN code labels on the host and calibration board box, or the SN code of the instrument can be viewed through the host computer.

2. Before calibration, please make sure that the instrument and the calibration plate box are clamped tightly, otherwise the calibration will not pass.

Modify the calibration value description:Instrument calibration and modification of instrument calibration values can be realized through the host computer software.

Note:

Carefully operate the function of modifying the calibration value, which is better operated by the original manufacturer or a qualified metrology research institute, onlyWhen the actual parameters of the standard board are inconsistent with the calibration parameters, they are repaired according to the actual parameters of the measurement standard boardChange! Before modifying the standard value, we recommend that you back up the original standard value.
