Calibration
8.3 Calibration of the black standard tem-
perature
NOTE:
Calibrate the unit before and after every test. An optional
black standard thermometer and a corresponding adapter
(see chapter 5 "Accessories") are necessary for calibra-
ting the black standard temperature.
1. Use the adapter table
!
for the black standard ther-
mometer instead of the specimen table in the test
chamber. The arrow points towards the back panel of
the test chamber.
2. The external black standard thermometer
#
should
be placed in such a way that the black surface points
upwards, i.e. towards the Xenon lamp.
3. In the SUNTEST CPS+, start the calibration program
and enter the desired black standard temperature
value at the desired irradiance value.
CAUTION - Danger of burns:
The black standard thermometer can be very hot af-
ter a measurement has been taken.
When reading or removing the black standard ther-
mometer from the test chamber, it may be necessary
to wear protective gloves!
4. If required, put on protective gloves.
5. After approx. 60 minutes, interrupt the program with
"STOP", turn the black standard thermometer around
and immediately read the temperature in the display of
the black standard thermometer.
6. Enter the read-off temperature value (after the automa-
tic cooling period) in the SUNTEST controller and con-
firm with "ENTER".
7. The calibration factor calculated by the software is in-
dicated in the SUNTEST display and, after confirmati-
on by "ENTER", automatically used in each subse-
quent test.
