Menu – Calibrate

This screen is used to get an accurate pulses/unit value for a product. The idea is to simulate driving at field speed with the meter roller turning at a consistent rpm each time the calibration is done.

Calibration steps:

1. enter ground speed
2. set calibration meter speed (rpm)
   • start with Master switch off
   • switch product on with the power button
   • enter initial base rate
   • enter initial Cal Factor
   • press start, RC attempts to adjust flow/rate to target
   • if successful meter speed is locked
   • press stop
3. set Cal Factor (pulses/unit)
   • start with Master switch off
   • press start, turn Master switch on and let run to get an adequate sample amount
   • press stop and enter measured amount. Cal Factor is calculated.
   • press save to record new values
4. options to start over
   • if RC is not successful in locking the meter speed adjust initial Cal Factor, ground speed, PWM minimum, PWM maximum or machine metering drive range. Start step 2 again.
   • to redo the meter speed the lock button can be pressed to unlock. RC will then attempt to find a new meter speed when step 2 is redone.
   • to start from a previously saved setting the lock button can be pressed to lock. Then continue with step 3.
