Yield Calibration

IMPORTANT: Mass flow sensor must be calibrated every year to achieve accurate grain weight measurements.

Standard calibration must be performed in every crop that is harvested.

Low Flow calibration must be performed to obtain improved levels of accuracy in situations where large variations in grain flow rates occur.

From diagnostics and calibration icon (A), rotate selection dial (B) until calibrations menu (C) is highlighted.

Press confirm switch (D) and rotate selection dial until Yield is highlighted.

Press confirm switch and rotate selection dial until enter icon (E) is highlighted.

Press confirm switch to advance to next page.

NOTE: Operator must perform the standard calibration before the low flow calibration.

For the initial calibration, weight icon and comp number rest box are not enabled.

Rotate selection dial (A) until one of the following icons is highlighted:

• Next Page Icon (B) - allows operator to advance to next page of calibration.
• Weight Icon (C) - allows operator to enter scale weight in calibration factor once scale weight is known from elevator.
• Comp Number Reset Box (D) - allows operator to reset the low flow calibration.

  NOTE: For information on Calibration Factor, refer to Manual Adjust Calibration Factor later in this section.

• Calibration Factor (E) - allows operator to input a calibration factor number that was figured using a formula.

Press confirm switch (F) once desired selection is highlighted.

NOTE: Harvested weight (D) is the approximate weight of grain that was calibrated during the calibration process.

• Instantaneous Flow Rate (E) - arrow below bar graph indicates instantaneous flow rate.
• Standard Calibration Point (F) - green dot indicates standard calibration point (will be a red if a scale weight for standard calibration has not yet been entered).
• Average Flow Rate (G) - red circle indicates average flow rate during low flow calibration.

  NOTE: When calibrated correctly, red circle should end up towards left side of bar graph within range area (H).

Scale Weight Not Known: Rotate selection dial (A) until enter icon (B) is highlighted and press confirm switch (C).

NOTE: Scale weight can be entered after a calibration is complete (during calibration this indicates approximate weight of grain that has been harvested).

Scale Weight Known:

• Rotate selection dial until scale weight box (D) is highlighted and press confirm switch.
• Using numeric display, rotate selection dial until desired digits are highlighted and press confirm switch.

  NOTE: Repeat procedure until scale weight value is shown.

• Rotate selection dial until enter icon (E) is highlighted and press confirm switch to return to calibration menu.
• Rotate selection dial until enter icon (B) is highlighted and press confirm switch (C).
