19. Technical description
19.1 Factory calibration and adjustment
This unit 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 (certi-
fied 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.
19.2 Over current protection
The devices are equipped with an internal fuse not accessible from outside. If this fuse is blown, please
contact an electronic engineer or BINDER service.
19.3 Definition of usable volume
The usable volume illustrated below is calculated as follows:
b
c
c
b
a
a
C
B
A
A, B, C = internal dimensions (W, H, D)
a, b, c = distance to wall
a = 0.1*A
b = 0.1*B
c = 0.1*C
V
USE
= (A - 2 * a) * (B - 2 * b) * (C - 2 * c)
Figure 36: Determination of the useable volume
Technical data refers to the defined usable volume.
Do NOT place samples outside this usable volume.
Do NOT load this volume by more than half to enable sufficient airflow inside the chamber.
Do NOT divide the usable volume into separate parts with large area samples.
Do NOT place samples too close to each other in order to permit circulation between them and
thus obtain a homogenous distribution of temperature and humidity.
