To prevent unintentional or unauthorized adjustment, the instrument
is protected (locked) against all parameter changes while in normal
operating condition.
For each parameter change you have to enter the PIN of the instru-
ment. In delivery status, the PIN is "0000".
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterisation is terminated
correctly. If necessary, other measures must be taken to maintain the
safety function.
Here you can assign a suitable measurement loop name. Push the
"OK" key to start the editing. With the "+" key you change the sign and
with the "->" key you jump to the next position.
You can enter names with max. 19 characters. The character set
comprises:
•
Capital letters from A ... Z

Numbers from 0 ... 9
•
Special characters + - / _ blanks
