Calibration Summary 1. Select Setup Soft Key Menu 2. Navigate to Meter Calibration, and Select. 3. Select which Meter you would like to view or make changes to. Note: All Meters on a machine must be individually calibrated. Calibrations must be done each time a crop is changed.
Meter Settings Meter Rate: This value is automatically set during the meter calibration procedure. It can also be set manually. Changing the setting affects the displayed increments displayed. “Low” is for application rates up to 10 Lbs/acre, “Medium” is for application rates from 10 to 100 Lbs/acre, “High” is for application rates above 100 Lbs/acre. Low Alarm Point: This is the minimum meter RPM the monitor will recognize.
Meter Calibration & Procedures NOTE: For convenient calibration, your monitor is able to be disconnected from the tractor harness and attached to your tank harness. Meter calibration is a procedure that allows for accurately setting the individual meters to apply the desired rate of material. Before a meter calibration can be done the implement width must be entered and the speed calibration must be completed (See Sections 8.4.2 and 8.4.4 in your operator’s manual).
Procedure: Step 1: Having Selected Meter (1, 2 or 3) Calibration, “Target 10.0lb/ac” is displayed. Press the Toggle Button or Enter Key. Enter your desired “target” application rate by using the Toggle Button and Selector Knob to edit. Once the desired target application rate is set, press the Toggle Button or Enter Key to accept. In the example below “Target” is set for 100lb/ac. Measure and record the weight of the empty calibration bucket.
As stated on the screen: set the gearbox on the implement to a setting of 100 using the increase/decrease switch on the side mounted control box and PRIME THE METER to ensure full flow at the beginning of the calibration. Note: Empty the product out of the calibration bucket, this is not needed for the rest of the calibration procedure. Once this step is complete, highlight the “Start Box” using the Selector Knob and use the Enter Key or Toggle Button to select Start.
Step 3: The screen now displays the number of revolutions counted during the calibration. “Weight 10.00lbs” is highlighted. Press the Toggle Button or Enter Key to enter the actual measured value of the material weight in the catch bin. Press the Toggle Button or Enter Key to accept the value.
Rate Check tips: • Weighing the product going into the tank will ensure greater accuracy. • Initial tank level check should be done after metering some product so a V-formation forms inside the tank. This will make for more accurate tank level check. • Use attached operator worksheets for keeping important information documented ie; cal weights, seeding rates, gearbox settings etc.
Rate Check Product Application Rate Check Calculation Seed size, seed type, seed coatings, seeding speed and other variables all have an effect on the actual product application rate (To use this method you MUST know the density (lb/cu.ft) of the product being calibrated). This Rate Check calculation compares actual weight of product seeded to actual acres applied. Step 1: Fill tank to a known level, or a known amount of product. (Note Tank Level, Figure 1) Step 2: Perform a regular calibration.
