Description of the sale of passport passports
How long is the lighting passport warranty?
Illuminated passports are guaranteed for one year without damage. If online registration is made, the one-year warranty period will be extended. During the warranty period, a free and complete calibration service will be available.
During the warranty period, each group will perform all repairs, including testing, battery replacement, replacement parts, and calibration (except that the housing is not replaced, performance and battery life is equivalent to a new machine.)
How often do I need to correct it?
It is recommended to return to the factory for calibration once in two years to ensure measurement accuracy.
Spectrometer calibration
Correcting the illuminated passport spectrometer must be performed in our measurement environment (tracking to NIST's light source and instrument).
During the warranty period, we provide a free calibration service. You can send the instrument to the 晟 instrument and ask to recalibrate the instrument and ask for assistance in handling the matter.
