7.6 Settings for test programs
The Xenotest 220 control panel allows for the program
-
ming of six test programs. The program parameters are
entered in pre-structured program steps on the instrument
control panel.
The Xenotest 220+ control panel allows for the program
-
ming of ten test programs in addition to the already pre-
programmed tests. The parameters are entered with user
guidance on the instrument control panel touch-screen.
NOTE – software documentation
The programming of the test programs is explained in the
separate software documentation manual.
Tab. 2, 3 and 4
contain the settings recommended by
Atlas for the Xenotest 220/220+ for the specified test
methods according to AATCC TM16, ISO 105-B02 and
ISO 105-B04.
