Installation
FIG. 14: SIX LOAD CELLS POSITIONED IN A
RECTANGULAR CONFIGURATION
NOTE:
In case there is some doubt concerning load point
assembly installation, contact your local Hardy
Dealer, or Hardy Application Engineering Depart-
ment or Customer Support Department for assistance.
You can orient the load point assemblies to meet your
system installation requirements. All load point
assemblies can be rotated 360
o
in 90
o
increments. The
examples above are recommendations only.
Level Requirements
For scales that must meet NIST Class 3 (OIML Class
3) specifications:
1.
The base plate support surfaces must be
within 0.2 degrees (0.4mm/100mm)
2.
The top plate support surfaces in the load
carrier must be within 0.5 degrees (0.9mm/
100mm)
For scales with accuracy requirements => 0.1%
1.
The base plate support surfaces must be
within 0.4 degrees (0.08mm/100mm)
2.
Top plate support surfaces in the load carrier
must be within 1 degree (1.8mm/100mm)
Stiffness
Load variations and external forces can cause support
surface level variations.
