5.2 Checking the zero and reference points
The zero and reference point check is for ongoing quality assurance in
accordance with EN14181 (QAL3) and should be performed when the unit is
warm from operation!
Make sure that the checking rod is in the photometer only for a short time,
since the heat in the measuring cell changes the checking rod value and may
result in an incorrect adjustment.
When working on parts of the system that are not insulated, it is imperative
that temperature-resistant gloves are worn!
