Configuration Lock Out
The meter is delivered with the programming not locked out, giving access to all the
programming levels. Once completed the meter programming the following security measures
are recommended:
1. Lock out the programming access to prevent from programmed parameters modifications.
2. Lock out Key Pad functions to prevent from accidental modifications.
3. There are two lockout modes: selective and total. If the parameters are going to be readjusted
frequently, make a selective lockout. If no adjustment is going to be made, make a total
lockout. Key Pad functions lockout is always possible.
4. The access to the lockout routine is allowed by entering a personalized code. We recommend
changing the code set at factory and to write down your personalized code and keep it in a
safe place.
TOTAL LOCKOUT
The access to the programming routines to read data is allowed even if all parameters are locked
out ALL=Yes, but
it will not be possible to enter or modify data
. In this case, when entering

PARTIAL LOCKOUT
When only some parameters are locked out, all configuration data can be read but
only non
