Procedures and entries are monitored in order to provide the user
with support.
The device is capable of detecting and reading out a great variety
of defective procedures.
In the case of manual operation, the error appears directly at the
display for a brief period of time. In addition to this, the last error
message can be viewed with the help of the appropriate menu
function.
Err appears at the left-hand display, and the three digit error code
at the right-hand display.
In the case of operation with a PC, the last three error messages
can be accessed by executing the ERROR? command (see
ERROR? command in the section entitled “Descriptions of Oper-
ating Commands”.
