1 Introduction
Thank you for purchasing a colorimeter from PCE Instruments.
The colorimeter PCE-CSM 6 is an ideal measuring device for application in the area of quality control and
offers high accuracy. When using the colorimeter, there are two different colour spaces available (CIE
L*a*b*C*h and CIE L*a*b*). After a measurement with the PCE-CSM 6, 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.

A reading which has been determined by using the “Standard Measurement” automatically serves as a
reference value. You can add one or more sample measurements to this reading. To do so, you have to
switch to the “Sample Measurement” screen:
1. Press the Enter button when you are in the results screen of the standard measurement
function. Now you get to the “Sample Measurement” screen.
2. Take a measurement (just like you did in the standard measurement).
3. Now you can see the results and the deviation to the standard in the following screen:
Note: While the measurement is in progress (time duration: ~ 1 second), all buttons are inactive.
To go back to the standard measurement screen, press Back .
5.3 Additional functions

7.2 Measuring device for liquids, pastes and powders PCE-CSM UTC
With the optional measuring device PCE-CSM UTC, you can determine the colorimetric parameters of
liquids, pastes and powders.
7.2.1 Design
The PCE-CSM UTC consists of a base plate (1), an alignment plate for the colorimeter (2), a measuring
chamber (3) with a measuring hole (31), a tank with filling level indication (4), a cover plate (5) and an
adjuster plate (6) with safety screws (7).

Manual
15
7.2.2 Operation
1. Place the colorimeter in the measuring device PCE-CSM UTC (as seen on the picture below) and
tighten it by using the adjuster plate (6) and the safety screws (7). The measuring aperture should
align with the measuring hole of the measuring chamber (3). Make sure that the colorimeter is in
the right place and tightened properly before moving on.
2. Fill the cuvette (4) with the desired medium and put it into the measuring chamber (3). The
cuvette has two matte surfaces at the sides. Only touch it on those two sides to prevent
measurement errors due to dirt. The cuvette is also equipped with a filling level indicator. Make
sure the filling level lies between the MIN and the MAX indication of the tank.
