Legal changes outside seal
This paragraph describes the legal changes, which can be carried out without disassembling the meter and
thereby breaking the legal seal.
All legal changes are fully traceable in an adjust log, which cannot be deleted. The number of legal changes
appears from the display (see paragraph
). Maximum 9 changes are possible.
The adjust log can only be deleted if the meter is disassembled and the legal seal is broken.
It appears from the meter’s software version whether a specific meter can be reset outside the legal seal.

17.11.1
Flow adjustment
The meter is initially verified from the factory. A new factory adjustment requires disassembling of the meter
and can only be carried out by Kamstrup A/S. When the meter has been locked it is only possible to make a
percentage correction of the flow curve at three individual points. This is called re-adjustment.
17.11.2
Re-adjustment
A re-adjustment can be made without disassembling the meter and thereby breaking the legal seal. The following
restrictions apply:
- Maximum 9 (nine) re-adjustments are possible.
- Maximum adjustment compared to the factory adjustment is +/-10%.
- Each readjustment is logged in the meter.
During a re-adjustment the flow curve is corrected at three fixed points and the curve will be re-adjusted to these
new points.
IMPORTANT: The laboratory, which makes the readjustment, must attach an adjustment label with the valid
adjustment number to the meter. Naturally, this number must be identical with the number (AX) in the meter’s
display.
17.11.3
Reset
The meter can be reset via the optical eye. This is used in connection with re-verification by authorized
laboratories. All loggers and registers including the legal volume register are reset. Only the adjust log and the
clock are not reset. At the same time the meter is set to transport mode and the radio is switched off. The
following restrictions apply to reset:
- The meter can maximum be reset 9 times.
- Each reset is logged in the meter.
IMPORTANT: The laboratory, which resets the meter, must attach an adjustment label with the valid adjustment
number to the meter. Naturally, this number must be identical with the
number (AX) in the meter’s display.
