24.1 Factory calibration and adjustment
The chambers were calibrated and adjusted in the factory. Calibration and adjustment were performed
using standardized test instructions, according to the QM DIN EN ISO 9001 system applied by BINDER
(certified since December 1996 by TÜV CERT). All test equipment used is subject to the administration of
measurement and test equipment that is also a constituent part of the BINDER QM DIN EN ISO 9001
systems. They are controlled and calibrated to a DKD-Standard at regular intervals.
Repeated calibrations are recommended in periods of 12 months.
24.2 Over current protection
The chambers are equipped with an internal fuse not accessible from outside. If this fuse is blown, please
contact an electronic engineer or BINDER service.
