Calibration
After the MSI has been properly installed, calibration of the weighing system must be
done in conjunction with the integrator. Refer to the integrator instruction manual for
programming and calibration. The calibration is initially done using the supplied test load.
Material tests are recommended to achieve maximum accuracy.
Test Load
The test load value for your MSI is given on the accompanying data sheet. The value is to
be entered into the dedicated programming parameter of the integrator, in kilograms per
meter or pounds per foot. An equal number and mass of weights must be applied to each
suspension during the span calibration function.
If the actual idler spacing differs from that recorded on the design data sheet, the test
load must be recalculated as follows. Failure to do so will cause the design test load
value to be in error.
test load =
The above calculation must be performed for each MSI scale suspension using the
weights designated for that particular suspension.
Enter the average value of the two calculations into the integrator's Test Load Parameter
(test load value "A" + test load value "B")/2 in kilograms per meter or pounds per foot.
Zero
Perform the zero calibration as described in the Calibration section of the integrator
manual.
Span
The test load used in the calibration procedure is the two sets of test weights ( 1 to 12 )
supplied, one for each MSI suspension.
Place each set of the test weights onto the calibration weight bar of the respective MSI
as shown. Perform the span calibration as described in the Calibration section of the
integrator instruction manual.
After the span calibration has been completed, remove the test load and store it.
