VL53L4CD Large Calibration Offsets

will3
Associate III

Our use of the VL534LCD is within what we call a bin.  A long rectangular container.  The sensors job is to measure the distance to items placed into the bin.  Very contained environment with little interference.  

When we calibrate the sensor we do this when our bin is empty.  There is a white panel always at the beginning of the container bin which moves forward (backwards) along a track when items are placed in it or taken out.  When it is empty it is stationary at 231mm.  So,  we calibrate using 231mm.

When we calibrate to 231mm we get back offsets from the sensor > -45.  These seem unusually large to me? Why would this be?
