Material Calibration Mode
Use this calibration mode if you want to calibrate the scale with a known amount of material. The material must
be pre-weighed or post weighed.
Use the following steps to perform a material calibration.
1. Press the
Material
softkey on the BCi display. The BCi will display
Span Cal
and
Exit =>
softkeys.
2. The
Span Cal
softkey will initiate the calibration sequence for the span calibration. This is similar to the
zero cal but material will be passed over the scale during the calibration test.
3. The operator will press
Start
, the integrator will start taking span averages. At some point the operator
will then press the
Finish
softkey to end the sequence.
4. The BCi will prompt the operator for the amount of material that was weighed. The operator may key in
the new value and press
enter
or cancel to exit with no changes.

5. The process can be aborted at any time by pressing the
Exit =>
softkey.
Zero Cal Calibration Mode
By selecting this mode will calibrate the integrator based on a zero test. A zero calibration is based on the number
of belt revolutions is established during the belt speed sensor calibration.
Use the following steps to perform a Zero Cal calibration.
1. Press the
ZERO
key on the integrator. The previous zero information will be displayed with the zero scale
menu.
2. The operator will press the Start key.
3. The Zero Cal test will run, and after the test is completed the new zero error% will be shown on the
display. The operator needs to press either the Yes softkey to accept that value or No softkey to not see
the new zero.
4. There is also a config mode zero test which goes through the same steps as the zero cal calibration but
this is accessed through the Integrator calibration softkey on the main menu.

Complete System Calibration Test Used In Conjunction with integrator
Calibration
There are three types of tests that are also used in conjunction with calibrating the complete system. They are:
•
Material testing
•
Simulated (resistor) load testing.
•
Maintenance testing
Material testing is used only with the material calibration and the simulated (resistor) load testing is used only
with the Auto Calibration and the Timed Cal.
The following sections describe how to perform a material test and a simulated load test.
