1 Introduction
Thank you for purchasing a colorimeter from PCE Instruments.
The colorimeter PCE-CSM 3 is an ideal measuring device for application in the range of quality control
and offers a high accuracy. When using the colorimeter, there are two different colour spaces available
(CIE L*a*b*C*h, CIE L*a*b*). After a measurement with the PCE-CSM 3, the reading can be used as a
standard value. Other readings can be recorded as a sample and later be compared to the reference
value. In addition to the individual colour space coordinates, the deviation between the readings is also
displayed. On the internal memory of the colorimeter, you can store up to 100 reference values and up to
20000 samples. The measured data can also be transferred to a PC via USB and analysed with the
included PC software.
2 Safety notes
