ACCESS CODE
All data of the Promag 33 measuring system are protected against
unauthorised access. Only by first entering a code number in this function
programming is enabled and the settings of the instrument can then be
altered. If, in any function, the
6
operating elements are touched, then the
measuring system jumps automatically into this function and the display shows
the prompt to enter the code number (if programming is locked):
→
Enter code number 33 (factory setting) or
→
Enter personal code number (see “DEF. PRIVATE CODE”, page 77)
Note!
•
After jumping to the HOME position programming is again locked after
60 seconds if no operating element is touched during this time.
•
Programming can also be locked by entering any number (not the customer
code number) in this function.
•
If you can no longer find your personal code number, then the
Hauser service organisation will be pleased to help you.
•
Certain functions can only be modified by entering a special service code
number. This is known to your E+H Service organisation. Please contact
your E+H Service for any further information you may require.
