ZERO
The ZERO key will reset the weight on a scale to read zero (either lb or kg unit of
measure). If the ZERO key is pressed when a pad holds weight, the current weight
becomes the zero condition for the pad. The ZERO feature can be useful to cancel the
weight of weighing fixtures such as tail cones or wheel chocks. When the weight is
removed, a negative weight is displayed until the system is re-zeroed. The ZERO
function is also used when the scale shows a non-zero value with no weight on the
pads. NOTE: The system includes a feature called Auto Zero Tracking (AZT). AZT
corrects for slight zero changes during normal operation. An example of a zero change
could be a buildup of dirt on the pads.
The ZERO key can also be used to clear the accumulated total. Press and hold the
ZERO key until the display screen shows ".", then release the ZERO key. The
accumulated total and the accumulation number will be reset. All scales connected in
the system through interconnect cables will also be zeroed. The entire system can be
zeroed with one press of the ZERO key.
