5.2 Calibration Setup Procedures
5.2.1 Unit of Measure
The unit of measure can be set to ounces, pounds, tons, grams, kilograms, or metric tons.
Any weight value input to the module (for example, REFERENCE WEIGHT, SPANWEIGHT)
is in the currently selected units. The unit of measure can be set at any time, not just at
calibration. Setting the unit of measure before calibrating reminds you what unit of measure
is being displayed.
Note:
The weigh scale module does not need to be calibrated again after
changing the unit of measure.
5.2.2 Motion Tolerance
Motion Tolerance defines the amount the weight reading needs to change in a 1 second
period of time to make the scale go into MOTION status. If the change over the last 1
second is less than the Motion Tolerance, the scale will not indicate in motion. “Motion
Indicate” means the weight on the scale is currently changing. The scale cannot be
calibrated, tared, or zeroed while in motion.
5.2.3 Zero Tolerance
Zero Tolerance sets the range of weights so that the Zero Command works as an offset of
the calibrated Zero. The amount of weight zeroed off is cumulative. The zero command fails
if the current gross weight plus any previously zeroed amount exceeds the Zero Tolerance.
5.2.4 Auto Zero Tracking
Auto Zero Tracking adjusts for zero weight automatically. This capability allows the module
to ignore material build-up in the weighing system within a preset auto zero tolerance. For
auto zero to work, the current gross weight must be within the auto zero tolerance. The
current gross, plus any previously zeroed weight must be within the Zero Tolerance level
value and the scale must not be in motion. Zero This is not used in all applications and
should be reviewed before use.
Track Enable either enables the Auto Zero tracking if on or disables the Auto Zero if off.
Note:
The amount of weight zeroed off is cumulative. The Auto Zero command will
not run if the current gross weight plus any previously zeroed amount exceeds the
zero tolerance value.
