Zero calibration
Perform the zero calibration as described in the Calibration section of the integrator operating
instructions.
After the completion of the zero calibration, a span calibration, as described in the belt scale
integrator operating instructions, can be performed with the test weight(s) applied. Be sure to
stop the conveyor when applying and removing the test weight.
6.6
Span calibration
1. The span reference (test load) is simulated using the test weight.
2. Apply the calibration test weight(s) to the scale.
3. Perform the span calibration as described in the Calibration section of the integrator
operating instructions.
After completing the span calibration, remove the test weights and store them. With a successful
zero and span calibration, and with the test weight(s) removed from the belt scale, the belt scale
system is ready for operation. Ensure that the belt scale integrator is left in RUN mode.
6.7
Material test
To achieve accuracy with respect to absolute values, perform material tests. Refer to the
associated integrator manual for instructions on material testing.
6.8
Re-rating
Consult your Siemens representative for any significant change in rate, speed, and/or idler
spacing from original design specifications to maintain proper design parameters.
