Calibration of irradiance with the
XenoCal Global Sensor
NOTE:
Calibrate the unit before and after each test. The optional
XenoCal Global Sensor and an adapter table for the Xeno-
Cal sensor (see chapter 5 "Accessories") are necessary
for calibration.
The XenoCal Global Sensor can be used to calibrate and
adjust global irradiance in the SUNTEST CPS / CPS+ in
a wavelength range of 300nm to 800nm.
This adjustment is possible for all filtrations. In order to
minimize the systematic error, which is caused by diffe-
rent spectral energy distributions, filter correcting factors
are stored in the program control of the SUNTEST CPS+,
which will automatically be used.
1. Mount the adapter table
!
for the XenoCal Global
Sensor instead of the specimen table in the test cham-
ber. The arrow points towards the back panel of the
test chamber.
2. Insert the connector cable
#
in the XenoCal Global
sensor
"
and guide the connector cable
#
below the
adapter table
!
to the PC.
3. Start the program XenoSoft and ONLINE measurement.
4. In the Suntest CPS+, start the calibration program and
input the irradiance at which calibration is to be done.
5. After approx. 30 minutes, enter the actual irradiance
value displayed in the XenoSoft to the corresponding
field in the display unit and confirm with "ENTER".
6. At the end of the automatic cooling period, the calibra-
tion factor calculated by the software is indicated in
the display unit and automatically used in every sub-
sequent test.
