23. Technical description

23.1 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

(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.

23.2 Over current protection

The KT is protected by a unit-protection against over current, accessible from the outside, IEC C 14

connector plug with circuit breaker. Replace this fuse only with a substitute of the same ratings. Refer to

the technical data of the respective device type. If this fuse is blown, please inform an electronic engineer

or BINDER service.

23.3 Definition of usable volume

The usable volume illustrated below is calculated as follows:

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

USE

= (A - 2 * a) * (B - 2 * b) * (C - 2 * c)

Figure 12: Determination of the usable 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 and humidity.
