Calibrating Solution Pump

The SPRAYSTAR system will automatically calibrate itself in order to provide an optimal control for a particular situation.

NOTE: Do not perform this procedure for erratic solution pump rate or pressure if the A and B numbers are within range. If A and B numbers are within range, see entries for erratic rate or pressure in Troubleshooting section.

The only time auto calibration needed is when the A and B values do not lie within their ranges or when one of the following has been replaced:

  • Solution pump/hydraulic motor assembly
  • Proportional valve
  • Hydraulic pump
  • Spray Rate Controller

NOTE: The A and B ranges are:

  • A = 2000-4500

  • B = 6500-9000

If the "A" value is in 4000 range, make sure "B" value is 8000 or greater for proper operation.
