Calibration

Mass flow sensor must be calibrated in order to achieve accurate grain weight measurements. Standard Calibration procedure must be performed in every crop that is harvested. In addition, the optional Low Flow Compensation procedure may be performed to obtain an improved level of accuracy in situations where there are large variations in grain flow rate.

The following paragraphs describe the different screens that are used in the calibration procedure.

This section displays if the mass flow sensor has been calibrated to the desired crop.

If the system has not be calibrated a message displaying "System NOT Calibrated" will be displayed.

If standard calibration has been performed a bar graph indicating the flow rate sensor has been accurately calibrated.

If a standard and low flow calibration has been completed, the bar graph will expand to show an increased area of accuracy.

This screen indicates whether Standard Calibration procedures or optional Low Flow procedure is to be performed.

Press letter button next to "Calibration Mode" to switch between "Standard Calibration" and optional "Low Flow Calibration".

This screen allows calibration procedure to be "Started" or "Stopped".

This screen indicates the approximate weight of grain that has been harvested during the calibration process.

This screen allows scale weight to be entered after a calibration run is complete (during calibration run, indicates approximate weight of grain that has been harvested).

Value shown here allows mass flow sensor to read accurately. This value will be updated automatically by Calibration procedure. This value can also be adjusted manually.
