Hardy Floor Scales

Material
Substitution:
•
When certified test weights are not available
you can use an accurately weighed material
instead.
•
The material must be weighed on a second-
ary, calibrated scale and delivered to the site
of the primary floor scale for calibration.
•
The secondary calibrated scale should be of
the same accuracy or greater and have a
capacity approximately equal to the primary
floor scale.
SCALE VERIFICATION
Step 1.
Get a test weight that is equal to 10% of
the full scale capacity.
Step 2.
