STANDARD COUNTING SCALE
PREPARING THE SCALE FOR USE
The XTC Standard Counting Scale is a high performance industrial counting scale that accurately and
dependably counts parts of all shapes and sizes.
This manual provides not only the detailed information on how to operate the scale, but also useful
messages for service and maintenance.
Please read this manual thoroughly and familiarize yourself with all the safety requirements. All service
procedures must only be performed by authorized personnel.
This chapter gives detailed instructions and important information regarding the successful installation of
the Xpress Standard Counting Scale.
ENVIRONMENT
Before you install the scale, identify the best location for the equipment. The proper environment
enhances its operation and longevity. Keep in mind the following factors, which might have a negative
influence on the scale's operation:
Vibration: Vibration diminishes the scale’s ability to measure accurately. Electrical machinery such as
conveyors and drill presses can cause inaccurate and non-repeatable readings. The scale may also
read inaccurately if it is not leveled properly.
Air currents: Moving air can cause the scale to read wind movement as an additional force and cause
inconsistency in the weighing results.
Friction: A scale cannot measure accurately if an object is rubbing or pressing against the scale
platform.
UNPACKING AND ASSEMBLY
Please inspect the package immediately upon receipt. If the box is damaged, check for internal damage
and file a freight claim with the carrier if necessary. If the container is undamaged, open the box, remove
the scale and place it on a solid, flat surface. Please keep the packing material and shipping insert in
case you need to return the scale to an Xpress representative.

APW ENHANCEMENT
APW enhancement improves the accuracy of an APW. APW enhancement is based on the fact that an
inaccurate APW, while not able to accurately count large numbers of parts, will reliably count a small
number. This allows a determination of APW based on a larger weight. Given enough enhancements,
the APW becomes very accurate.
This function permits the operator to continuously update the APW based on larger and larger samples.
As additional pieces are placed on the scale, a new APW can be calculated based on the new total
sample weight and count.
The APW can be enhanced constantly up to 4% of the scale capacity. To ensure a minimum APW initial
accuracy, a sample weight of at least five display increments must be used. There is a selection in setup
mode which increases the minimum sample to 0.015%, 0.1% or 0.2% of capacity.
When using APW enhancement, you must not add more pieces to the scale than what can be counted
accurately using the current APW (about the same pieces, which have already been counted). If this
maximum is exceeded, a warning of [OVER] will be displayed for approximately two seconds then will
automatically clear. The operator can remove parts until [OVER] will not be displayed again.
If the operator ignores the [OVER] display and adds more pieces (or removes more in count-out sample
mode), no further APW enhancement will be done for the current transaction. If the proper procedure is
followed, the scale will continue to enhance the APW until 4% of the scale capacity is reached. Once the
counting weight reaches 4%, APW enhancement is discontinued.
Notice: The APW inputted via keyboard or recalled from an ID can not be enhanced.
