3.3.2.2 Auto Zero

The ‘Auto Zero’ optional feature supplies an automatic correction to creeps in

the zero level during a special mode (such as the fill-mode or the WIM-mode),

caused by dust, temperature etc.

When this feature is activated and the card is inside the special mode, the

board automatically clears the gross weight if some pre-defined condition is

satisfied: All readings within some ‘continuous duration’ are inside the ‘zero

range’.

Say, all readings during 3 consecutive seconds are between –1g and +2g.

These ‘continuous duration’ & ‘zero range’ are user-defined by the following

parameters.

The auto Zero effect is temporary – it expires upon the exit from the special

mode, or card reset.

3.3.2.2.1 Activate

Activates the ‘Auto Zero’ feature. When ‘Activate’ is deselected

(unchecked), an “Auto Zero’ operation will never take place.

3.3.2.2.2 Max Zero

The upper bound of the ‘zero range’ (+2g in the example).

Note

: Max. Zero refers to the

original

zero level as was defined during the

calibration procedure.

3.3.2.2.3 Min Zero

The lower bound of the ‘zero range’ (-1g in the example).

Note

: Min. Zero refers to the

original

zero level as was defined during the

calibration procedure.

3.3.2.2.4 Time limit

The size of the ‘continuous duration’ (3s in the example).
