Calibrating
After the weighfeeder 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.
A test sheet has been provided with the weighfeeder detailing the entries used during factory
calibration.
The calibration is initially done using the supplied test chain. (For models with skirtboard
covers, the cover will need to be removed for test chain calibration. The shear gate may also
need to be raised to apply the calibration chains to the belt.) Material tests are recommended
to achieve maximum accuracy.
5.1
Test load
The test load value for the weighfeeder is based on the number of chain strands. The exact
weight of the test strand is stamped on it.
5.2
Zero
Perform the zero calibration as described in the Calibration section of the integrator manual.
Note
This calibration should be at least three belt revolutions or five minutes, whichever is longer.
5.3
Span
The test load used in the calibration procedure is the test chain provided that mounts to the
conveyor leg with two mount screws.
Perform the span calibration as described in the Calibration section of the integrator instruction
manual.
Note
This calibration should be at least three belt revolutions or five minutes, whichever is longer.
