Material Test

The MMI is guaranteed to be accurate to ± 0.25% when installed on a conveyor in
accordance with this manual and meeting the qualifications outlined in the Belt Scale
Applications Guidelines (7ML19985GA01). This guarantee is based on calibrations
performed using the test weights furnished with the scale and as referenced on the
previous page.
When the existing conditions are such that the installation of the scale cannot meet the
above mentioned requirements for an approved installation it is recommended that
Material tests be performed. This will enable the user to compare the present scale
results to the results of the material tests. The scale is then adjusted or factored so that
subsequent scale calibrations with test weights will agree with actual run of material.

Re-Rating

To be sure that proper design parameters are maintained, consult your Siemens
Milltronics representative for any significant change in rate, speed and /or idler spacing
from original design specifications.
