50 Installation & Operation Manual
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 as established during the belt speed sensor calibration.
Use the following steps to perform a Zero Cal calibration.
1. Ensure that there is no material on the belt.
2. Press the ZERO key on the integrator. The previous zero information will be displayed with the zero scale
menu.
3. The operator will press the Start key.
4. 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.

Auto Cal Mode
By selecting the Auto Cal mode, the integrator 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 integrator display. The integrator will display Test Weights , Test Chain ,
and Exit softkeys.
2. Select either the Test Weights softkey or the Test Chain softkey depending on the span calibration method
you are using.
