Test Load
The test load value is required for calibration of the integrator. Enter the calculated value
into the associated programming parameter of the integrator in kilograms per meter or
pounds per foot.
The test load value is calculated as follows:
Test load = calibration weight (kg) or (lb)
idler spacing (m) (ft)
Where: idler spacing = L/2 [minimum 0.6 m (2.0 ft)]
Final Calibration
Once installation and load cell balancing are complete, release the belt and allow it to
ride normally on the conveyor. Run the conveyor for at least fifteen minutes to limber the
belt prior to calibration.
Program the belt scale integrator with parameters suitable for the application. When
programming is complete, the system is ready for calibration.
Zero
Perform a zero calibration after the conveyor has been run long enough to allow the belt
to limber up and take its natural formation (10 to 20 minutes). Perform the zero calibration
as described in the integrator instruction manual while the conveyor is running empty.
