After fastening the column to the base install all the bench scale and column leveling
feet as shown in the image below.
Place the bench scale on an environmentally sound level surface and adjust the feet on
the bench base only.
(Do not adjust the column feet at this point) until the bullseye level shows that it is
level as shown in the image below. Once the scale is positioned and level adjust the
column feet until they sit firm to the surface (It is important to make sure that the
column feet are taking the pressure off the column only). Finally, tighten all lock
nuts.

Bullseye Level Adjusting
Overload Stop
The overload stop is a set crew placed on the underside of the base and is designed so
that the load cell bottoms out when more weight is applied than the scales capacity. To
adjust this screw simply apply the weight that matches the capacity of the scale plus 5%
and adjust the screw in until it hits the cell. The overload stop is now set to stop at
anything over 105% of the scale’s capacity. Use blue Loctite when setting screw.

Indicator Installation
Mount the indicator on the column mounting bracket. Tighten the wing nuts to secure
the indicator to the column.
Terminate the load cell wires to the load cell terminal located on the main board of the
indicator. Reference the indicator manual that is being connected to the DuraShield
bench scale for load cell termination points.
See the diagram below for load cell wire color code.
Calibrate the scale using certified calibration weights and to the scale’s capacity when
possible.
After calibrating the scale, test it at the low end, middle and high end to insure it is
working properly. Once the scale is confirmed working, the scale is now ready for use.
