14.2.3 Legal for trade counter

If the 'legal for trade' option is enabled, the legal for trade counter is incremented every time a backup into EEPROM
is requested if at least one (or several) of these settings has been modified:
•
legal for trade switch
•

stability criterion

•
decimal point position
•
maximum capacity
•
number of calibration segments
•
calibration loads 1/2/3
•
scale interval
•
span adjusting coefficient
•
calibration place/place of use g values
•
sensitivity
•
A/D conversion rate
•
filtering configuration (activation option, order and cut-off frequencies)
•
weight unit
•
flow rate time unit
•

zero functions

14.2.4 Legal for trade checksum

If the 'legal for trade' option is enabled, a new legal for trade checksum is calculated every time a backup into
EEPROM is requested if at least one (or several) of the settings listed above has been modified.
14.2.5 Zero functions
The zero tracking and the initial zero setting can be respectively enabled by setting b
activated, both options are effective on a ±10% range of the 'maximum capacity' (±2% if the 'legal for trade' option is
enabled).
!
When the initial zero is used, you must use a stability criterion other than 0 to be
not affected by transient effects at power-up.
14.2.6 Stability criterion
The stability criterion defines the interval on which measurements are considered as stable. Motion is indicated by b
bit of the measurement status register. A measurement is stable if X consecutive measurements following the
reference measurement are included in the stability interval (see following table) else the current measurement
becomes the new reference measurement. X depends on the A/D conversion rate.
