6.1 Calibration
After all parts of the weighing system (belt scale, speed sensor, integrator) have been properly
installed and connected, the weighing system and integrator must be calibrated. The calibration
is initially done using the test weight(s), however material tests are recommended to achieve the
greatest accuracy. Refer to the integrator operating instructions for programming and calibration
details and for information about material tests. All operating instructions are available for
download at our web site:

6.2 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:
6.3 Balancing
For applications where the conveyor loading does not repeat in locations across the width of the
belt, such as side-to-side loading, electronic balancing of the two load cells is recommended.
Balancing is completed during the initial start-up, but should be repeated if either load cell is
reinstalled or replaced. Refer to the associated integrator manual to complete the balancing
procedure.
When balancing load cells, apply a test weight to the extreme sides (side A or B), as required.
6.4 Final calibration
Program the belt scale integrator as suggested in its operating instructions and with parameters
suitable for the application. With programming complete, the system is ready for calibration.
A zero calibration can be performed after sufficient running of the conveyor allows the belt to
limber up and take its natural formation. A zero calibration is performed in accordance to the belt
scale integrator operating instructions with the conveyor running empty.
