6.5 Calibration of the XENO-
SENSIV sensor
For the calibration of the XENOSENSIV sensor two
sensors, namely the master and the XENOSEN-
SIV sensor, are placed in the test chamber on two
adjacent sample holders. The sensors ae then in-
terconnected by means of the calibration adapter
(fig. 27).
Care must be taken that the input sockets
of the calibration adapter are tied up to the
corresponding sensors.
Then connect the plug-type connector of the adap-
ter to the connection cable of the program control.
Set the switch of the adapter to BST for calibration
of the black standard temperature or to E for the
irradiance. The calibration program can then be star-
ted.

6.6 Insertion of the end
plug (fig. 28)
If no XENOSENSIV sensor is fitted, the coupler
socket in the test chamber is secured with an
adapter plug.

Sample back cooling

For special weathering procedures a dew effect can
be produced on the sample surface. This is achie-
ved after changing over from the exposure phase
to the dark cycle under especially selected con-
ditions of temperature and humidity and under si-
multaneous spraying of the sample backs. (Drop-
ping below the dew point).
In order to achieve an efficient sample cooling, the
samples are placed on the sample holders un-
backed.
