18. Self-test function
The self-test function enables an automated check of the proper chamber functioning as well as a targeted
and reliable fault analysis. In this case, the chamber successively undergoes various defined operating
states, which serves to determine reproducible characteristic values. These characteristic values provide
information on the performance and precision of the individual functional systems of the chamber (e.g.,
heating, refrigeration, humidification) of the chamber.
The results of the self-test are stored in the service recorder of the controller. You can export them using
the controller’s USB interface and send them to BINDER Service (use function “Export recorder data” to
USB stick, chap. 17). BINDER Service will evaluate the data using an analyzing tool.
In order to allow an optimum comparison of the determined characteristic values with the
reference characteristic values, the ambient temperature should be in the range of +22 °C
+/- 3 °C / 71.6 °F +/- 5.4 °F .
The chamber shall be unloaded (empty with standard equipment).
