Load profile memory access error (critical error)
This error message appears in the event of repeated failures when
accessing the load profile memory.
Load profile data will be marked in the status code (bit 2 "corrupted meas-
urement" and bit 0 "critical error" set).
It may not be possible to access the load profile memory. The memory may
contain incorrect data. The meter must be exchanged.
The same applies to messages where the bit is set: F.F .. .. 5x.
Communication unit access error (non-critical error)
The meter sets this message in the event of repeated failures to access the
communication unit. Communication fails or is slow.
The error can be reset via communication. If it reoccurs, replace first the
communication unit, check the function again. If the error still occurs, the
meter must be exchanged.
The same applies to messages where the bit is set: F.F .. .. 5x.

Group 3 of error messages
The first digit in the third group can have the value 0 (no error message) or
1 (error message set).
The second digit can have values between 0 (no error message) and F
(all four error messages set). Significance:
Program checksum error (fatal error)
The meter does not operate and must be exchanged.
The same applies to messages where the bit is set:
