    SAM 400 SPEED-AREA-DISTANCE METER Operation Figure 1 Channel Indicator Fwd Speed Part/Total Area Engine Hours Part/Total Distance Work Rate Decrease Cal Increase Cal Factor Factor Override Area/Distance accumulation ENTER PROGRAM SELECT CHANNEL MODE Reset Part/Total Area/Distance The instrument will normally be powered through the vehicle ignition system and will be on whenever the vehicle ignition is on.

  • Page 5: Forward Speed Display - Channel 1

    SAM 400 SPEED-AREA-DISTANCE METER Forward Speed Display - Channel 1 Channel 1 displays the current forward speed. Forward speed is measured via a sensor suitably mounted to a wheel hub or a convenient location to the vehicle drivetrain. Speed is displayed either in miles/hr or km/hr according to the units selected in the CAL Mode.

  • Page 6: Reset Area / Distance Totals

    SAM 400 SPEED-AREA-DISTANCE METER For both area and distance there are two memory registers - a 'Part' total ("tot.1") and a 'Full' Total ("tot.2"), which can be independently reset. For example the part total register may be utilised for individual jobs, fields etc, whereas the 'full' total register may be the daily total.

  • Page 7: (Ii) Optional Width Correction Interface

    (iii) Area Compensation Interface An Area Compensation Interface (ACI) connects between the SAM 400 and the sprayer switchbox. It detects which boom sections are on/off in order for the instrument to calculate the actual working width and apply the correct rate.

  • Page 8: Work Rate - Channel 4

    SAM 400 SPEED-AREA-DISTANCE METER Work Rate - Channel 4 This is the instantaneous work rate displayed in either hectares per hour or acres per hour, depending on the units set in the Cal mode. If a WCI switch or an ACI is installed, the work rate is automatically recalculated based on the implement part width in operation.

  • Page 9: Calibration

    SAM 400 SPEED-AREA-DISTANCE METER Calibration The instrument has two calibration modes. In calibration mode 1 you can view and change the Forward Speed Sensor Factor, Implement Width/Nozzle spacing, No. of nozzles per section (if ACI installed), Units, and RPM Sensor Factor.

  • Page 10: Set Implement Width/Nozzle Spacing

    SAM 400 SPEED-AREA-DISTANCE METER Set Implement Width/Nozzle spacing The factor to be programmed is the full, effective working width of the implement. NOTE: If an ACI is connected on a sprayer, the implement width is equal to the nozzle spacing, e.g. 0.5 metres, You must then programme the ACI input (number of nozzles per section).

  • Page 11: Metric/Imperial Selection

    SAM 400 SPEED-AREA-DISTANCE METER Metric/Imperial Selection Press and hold the CAL button while switching the instrument on. Select the channel. 4 indicator bars will appear showing the units currently selected (fig. 5). Use the small left and right buttons to select the units.

  • Page 12: Manually Calculating The Factor

    Carry out this test whenever soil conditions or wheel sizes change. (iv) If an RDS Radar sensor is installed, the Speed Sensor Factor is 0.008 m (or 0.312 inches). If the calibration factor works out at over 2.000 m (78.78 inches), consider fitting additional magnets.
