CCC-codes with high resolution and 7 digits
If modules with pulse outputs are selected, high-resolution CCC-codes can reduce the battery lifetime. Please see
paragraph 10.4 re the meter’s battery lifetime.

The choice of 7 or 8 digits may influence the data communication
If the reading device has been hard coded to a given number of digits for the individual registers, there may occur
errors in the data communication if you select, for example, 8 digits on the meter, while the reading device is hard
coded to, for example, 7 digits.
This type of error most often occurs in systems in which meter and reading device use different communication
types, e.g. a PLC system in which the communication to an M-Bus converter takes place via RS-232 and the
communication to a MULTICAL® meter takes place via M-Bus. In case of suspicion that an error in the data
communication is caused by this, it can be checked by changing the CCC code in MULTICAL® to a variant with
another number of digits but of the same flow meter size.
To change the CCC code, an optical read-out head and METERTOOL are used.
