Calibrating
5
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 load data in the factory test sheets.
Material tests are recommended to achieve maximum accuracy.
5.1 Test load
The test load value for the weighfeeder is given on the accompanying test sheet. To calculate
the test load or to change it, refer to the integrator instruction manual.
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 based on a set of factory sized test weights
(2 or more). The weights ordered will not match this value exactly and the test load will need to
be adjusted during initial calibration.
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 weights and store them.
