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 mat
erial’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
