Backup memory access error
(non-critical error)
This error message appears if the backup memory could not be accessed
several times.
The meter may contain incorrect data and must be exchanged.
The same applies to messages where the bit is set:
F.F .. x3/x6/x7/xA/xB/xE/xF .. ..
Measuring system access error
(non-critical error)
This error message appears in case of repeated failures when accessing
the measuring system, possibly because of a completely discharged
supercapacitor, which causes an incorrect start-up behaviour.
Power-up meter and wait for a short time, then clear error via
communication.
If the error does not reoccur, it is recommended to equip
the meter with a battery. If the error reoccurs, replace the meter.
The same applies to messages where the bit is set:
F.F .. x5/x6/x7/xC/xD/xE/xF .. ..
Time device access error
(non-critical error)
The meter sets this message in the event of repeated failures when
accessing the time device. The calendar clock may display an invalid time
or date.
The error can be reset via communication
. If it occurs repeatedly, the
meter must be exchanged.
The same applies to messages where the bit is set:
F.F .. x9/xA/xB/xC/xD/xE/xF .. ..
Load profile memory access error
(critical error)
This error message appears in case of repeated failures when accessing
the load profile memory.
Load profile data will be marked in the status code (bit 2 "corrupted
measurement" 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 .. ..
