11.8 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 ’Adjustment mark’). Maximum nine 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.
See support of legal changes shown below:

11.8.1 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.
11.8.2 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 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 re-adjustment, 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.
