29. Technical description
29.1 Factory calibration and adjustment
This chamber was 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.
Factory adjustment was done in the center of the usable volume and under vacuum conditions. The sen-
sor is fixed in the middle of the expansion rack in a way ensuring good thermal conductivity (heat conduc-
tion). Measuring is performed in equilibrated state.
NOTICE
Risk of invalid calibration due to modified heat transmission when changing
between aluminum and stainless steel racks.
Undefined heating behavior.
∅ Do NOT change between aluminum and stainless steel racks.
 Use the delivered expansion racks only.
29.2 Over current protection
The chambers are protected by one or two miniature fuses against over current, accessible from the outs-
ide. The miniature fuses are located at the rear of the chamber next to the power cable connection. Each
fuse holder is equipped with a fuse clip 5mm x 20 mm (cUL-Version 6,3x32 mm). A fuse may be replaced
only with a substitute of the same ratings. Refer to the technical data of the respective device type.
