15.5 Self-test function (MK 56)
The self-test function enables an automated check of the proper chamber functioning as well as a targeted
and reliable fault analysis. It is available with the “Master”, “Service”, and “Admin” authorization levels.
In this case, the chamber successively undergoes various defined operating states, which serves to deter-
mine reproducible characteristic values. These characteristic values provide information on the perfor-
mance and precision of the individual functional systems of the chamber (e.g., heating, refrigeration) 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 service data” to USB
stick, chap. 14.6). BINDER Service will evaluate the data using an analyzing tool.
Activating the self-test mode
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).
