48 BCi Installation & Operation Manual
Auto Cal Mode
By selecting the Auto Cal mode, the BCi will calibrate the span using the number of calibration revolutions as
the reference for the calibration duration. Span calibrations are based on belt length defined by the number of
revolutions and use either static weights or test chains. Use the following steps to perform an auto calibration.
1. Press the Auto Cal softkey on the BCi display. The BCi will display Test Weights , Test Chain , and Exit
softkeys.
2. After the integrator has run the zero cal, a zero percentage error is displayed.
Figure 5-4. Zero Percentage Error Display
The operator has the option of accepting this error and setting the new dead load value or reject it with no
change made to the dead load.
3. The Span Cal softkey will initiate the calibration sequence for the span calibration. This is similar to the
zero cal but there is a load applied to the scale during this process. The load can be static weights, or
chains. To initiate this calibration sequence, press the
Start softkey.
4. After the integrator has run the span cal, the BCi will display the percentage of span error.
Figure 5-5. Percentage of Span Error Display
The operator can accept the error and the new span value will be stored, or the operator can reject it with
no change made to the span value.
5. The zero and span cal process can be stopped and restarted by pressing the Stop softkey and then press
Start . The process can be aborted by pressing the Exit=> softkey.
