15. Technical description
15.1 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 constituent part of the BINDER QM DIN EN ISO 9001 sys-
tems. They are controlled and calibrated in relation to a DKD-Standard at regular intervals.
15.2 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 = wall separation
a = 0.1*A
b = 0.1*B
c = 0.1*C
V
USE
= (A - 2 * a) * (B - 2 * b) * (C - 2 * c)
Figure 15: Determination of the useable volume
The 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.
