OPT3101: Measurement distance error during long-time measurement

Part Number: OPT3101

Tool/software:

When measuring with OPT3101 for a long time, errors will gradually occur in the measured distance of the object.
A target set at 175cm initially has no measurement error, but after 6 hours of measurement, it is measured at 190cm.
Could you please tell me about the error factors and countermeasures?
