The correct alignment of optical path and plate transport is checked by measuring light transmittance of 8 precisely aligned openings of the QC-plate.
The accuracy can be tested with three different neutral density filters which are calibrated against a reference photometer.
Repeated measurements with the QC plate will ensure precise and correct function of your reader.
The test plate will be delivered in a sturdy transport case. This is very convenient to safely transport the plate if it is used to verify several instruments in different locations.
