4. Measuring Procedure
4.1 Measurement of samples that are not self-luminous
Materials that do not luminaire on their own, are e.g. paper, leather, synthetics …
- Insert the Connector (4-17, Fig. 1) into the relevant input (4-9, Fig.1).
- Start colour meter by pressing “Power” (4-2, Fig. 1). The display will then indicate “0” for RGB.
- Take the handle of the pistol (4-17, Fig. 1), and place the sensor head (4-15, Fig. 1) near to
the material’s surface and press it slightly onto the surface.

RGB:
Press the “OP”-button (4-16 or 4-3, Fig. 1) once, so that the display indicates “Mesu”(for
measurement), and after several seconds R, G, B –values. Now you can lift the sensor head from
the sample surface. If you wish to perform a new measurement, proceed the same way.
HSL:
If you wish to determine the H, S, L values (hue, saturation, lightness), press the “RGB / HSL”-
button (4-7. Fig. 1) once, so that the display indicates the H-, S-, L- values. Press the “RGB / HSL”-
button again to return to the R, G, B –values again.
Compared to the RGB- values, the HSL values can emphathise the perception of the human eye
much better.
Note:
If you measure materials, that are not self-luminous, press the “OP”- button (4-16 or 4-3, Fig.1) once.
If the sensor head (4-15, Fig. 1) does not emanate a white light, proceed as following:
a. Start colour meter, and do not press the “OP”button.
b. Press the “LIGHT ON / OFF”button (4-8, Fig. 1) once. Now press the “OP”button. The
sensor head will then emanate white light.
If you press the “OP”button and the device does emanate white light, the device is ready for
application on surfaces that are not self-luminous.
If you press the “OP”- button and the sensor head does not emanate white light, the device is ready
for application on self-luminous surfaces.
4.2 Measurement on self-luminous samples
Self-luminous materials are e.g. LCD monitors, LED’s, …
Consider for this measurement mode, that there might appear larger statistical spreads for the
absolute measurement values. Thus this type of measurement should be mainly applied for relative
comparisons (before and after / new to old). First make sure that the sensor head does not emanate
any light.
Note:
If you measure materials that are self-luminous, press the “OP”-button (4-16 or 4-3, Fig 1) once, and
the sensor head (4-15, Fig. 1) emanates white light, proceed as following:
a. Turn on colour meter, do not press the “OP”-button.
b. Press the “LIGHT ON / OFF”button (4-8, Fig. 1) once. Now press the “OP”button. The
sensor head will then stop emanating white light.
If you press the “OP”- button and the sensor head does not emanate white light, the colour meter is
ready for application on self-luminous surfaces.
RGB:
Press the “OP”- button (4-16 or 4-3, Fig. 1) once, so that the display indicates “Mesu”(for
measurement). After several seconds it will indicate the R, G, B values. Now you can remove the
sensor head from the material surface. If you want to perform a new measurement, proceed the
same.
HSL:
If you want to determine the H, S, L –values (hue, saturation, lightness), press the “RGB / HSL”-
button once, so that the display indicates the H-, S-, L- values. Press the “RGB / HSL”- button again
to return to the R, G, B –values again.

4.3 Relative measurement
You can press during measurement, when the display indicates the R, G, B –values, the “REL”-
button (4-6, Fig. 1) once (Relative-mode), to switch to the Relative-mode. The display will then
indicate a blinking “0”.
If you now want to perform a new measurement, press the “OP”-button once (4-16 or 4-3, Fig. 1),
and the device will automatically calculate the difference between the new measurement value and
the one before. That value will then be blinking on the display. Press the “REL”-button again to
return to the standard measurement mode.
5. Calibration
The calibration does not refer to self-luminous samples. The delivery also contains a standard white,
which represents the 100 %- white value (not optically lightened). That standard is a white paper.
But you can also use other commercial standards (e.g. barium-sulphate- pellets) for the calibration.
Set the measurement device to the measurement mode for surfaces that are not self-luminous
(chapter 4.1).
a. Lay down the calibration standard on its flat side.
b. Take the handle of the pistol (4-17, Fig. 1), and place the sensor head (4-15, Fig. 1) near to
the material’s surface and press it slightly onto the surface.
c. Press “Function”- button (4-4, Fig. 1) and “CAL”-button (4-5, Fig. 1) for a while. The display
will then indicate the following points:
R CAL (Wait 30 sec.)
R 10 23
GCAL (Wait 10 sec.)
G 10 23
B CAL (Wait 10 sec.)
B 10 23

7. Change batteries
If the following symbol is indicated on the display, the battery capacity appears to be low. So the
battery needs to be changed. Loosen the screws of the battery compartment at the backside of the
device. Remove the old batteries and put in a new 9 V bloc battery. Consider the poling of the
batteries, if you do so. Reattach the cover of the battery compartment and secure with the screws.
8. Software
The software of the colour meter PCE-RGB 2 can be purchased optionally. The delivery of the
software will contain a separate instruction manual.
9. Disposal
Batteries may not be put in the household waste. They have to be given in the set up collection points.
NOTE: "This instrument doesn’t have ATEX protection, so it should not be used in potentially explosive
atmospheres (powder, flammable gases)."
