Reset functions
6.14.1
Resetting the hour counter
The operating hour counter can be reset in connection with e.g. change
of backup battery.
As the hour counter is often used to check whether the meter has been
in operation during the whole billing period (e.g. 1 year = 8760 hours)
the district heating supplier must always be informed, inwhich meters
the hour counter has been reset
In order to reset the operating hour counter switch off the supply voltage and disconnect the backup battery, then
wait until the display goes blank.
Connect the backup battery whilst activating the top pushbutton for min. 10 s until e.g.
energy is displayed.
Do not forget to switch on the supply voltage again. The operating hour counter has
been reset.
6.14.2
Resetting data loggers
Separate reset of data loggers, info loggers, max. & min. logger (without resetting the legal registers) can only be
carried out by means of METERTOOL. See paragraph 14 for further information.
6.14.3
Reset of all registers (total reset)
All legal and non-legal registers, including all data loggers, info logger, max. & min. logger can be reset by means
of METERTOOL or a short-circuit pen if the verification seal is broken and the internal “total programming lock” is
short-circuited.
Important! As the verification seal is broken, competent laboratories/utility companies with authorization to reseal
the meter must carry out this reset!
The following registers are reset: All legal and non-legal registers, including all data loggers, info logger, max. and
min. logger (max. values are set to zero, whereas min. values are set to 100000).
Note: ”Date” is after reset set to 2000.01.01 and subsequently changed to current date/time from the PC used for
the task. Therefore, do not forget to check correct date/time (technical normal time = ”winter time”) of the PC before
starting the reset function via METERTOOL.
