It is often very useful to know the message sequence when trying to
evaluate a message and determine its cause. The information in the
error memory is used for this purpose. (→ see also customer menu).
Scroll to the error memory display
The last 20 errors are displayed together with the error code
(for example Er 01), the error sequence, the date and the time.
Error sequence 01 indicates the most recent error, 20 the oldest.
