While the test is running, the message “F2 -> test repetition” is displayed.
If the test was successful, you can start dispensing (see 5). If it was not
successful, the display jumps back to the message from 3.

You have pressed the [esc]-key as option (in 3). For a few seconds the
message “ESCAPE -> ERROR 501” appears.
7
Finally the message “VALVE DEFECT ERROR 501” appears and stays
on. All the function keys of the MDC are locked. Switch off the MDC.
Remove the valve. It has to be send back to VERMES Microdispensing for
maintenance.
