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
0
bit or b
1
bit to 1. When
activated, both options are effective on a ±10% range of the ‘maximum capacity’ (±2% if the ‘legal for trade’ option is
enabled).
14.2.6 Stability criterion
The stability criterion defines the interval on which measurements are considered as stable. Motion is indicated by b
4
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.
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.
