Reset Function
Resetting the hour counter
The operating hour counter can be reset in connection with e.g.
replacement of 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 utility or waterworks must always be informed, in which
meters the hour counter has been reset.
In order to reset the operating hour counter you must first break the calculator seals, remove the calculator top
from the connecting base and wait until the display goes blank.
Remount the calculator top on the connecting base at the same time activating the top
pushbutton for minimum 10 s. until e.g. volume is displayed.
The operating hour counter has been reset.
Resetting data loggers
Separate reset of data loggers, info loggers, max. & min. logger (without resetting the legal registers) is only
possible by means of METERTOOL.
Resetting all registers
All legal and non-legal registers, including all data loggers, info logger, max. & min. logger can be reset by means
of METERTOOL or via NOWA if the verification seal is broken and the internal “total programming lock” is short-
circuited. As the verification seal is broken, this can only be done by an accredited laboratory.
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).
”Date” is after reset set to 2000.01.01
Via METERTOOL current date/time are changed 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.
