Group 1 of error messages
The first digit in the first group has no significance, since no error messages
are assigned to it.
The second digit can have values between 0 (no error message) and 3
(both error messages set). Significance:
Low battery (non-critical error)
The battery is missing or discharged. If there is no mains voltage at the
meter and the internal supercap is discharged (after about 3 weeks) then
the calendar clock will stop.
The error is deleted automatically when the battery voltage has again
reached a sufficient value (e.g. after inserting a new battery as described in
section 7.2 "Changing the Battery").
This error message only appears if the meter is parameterised as "fitted
with battery". Otherwise there is no check of the battery condition.
Invalid clock (non-critical error)
The meter has found that the calendar clock has stopped at some time,
e.g. due to insufficient power reserve (battery low). The clock is running,
but shows the wrong time and/or date.
The error is deleted automatically when the time and date have been set
correctly by the relevant formatted command or manually in the set mode
(see section 5.8 "Input of Formatted Commands"). or section 5.9 "Changing
Values in Set Mode"). If necessary, replace the battery.
