  3. Cleared “Invalid Setup …” Message from screen after clear key.

2.04    11/19/2002

  1. Fixed next calibration date, so CLEAR-KEY will exit without changes.

  2. Fixed Settle Time pointer calculation.  The VC3000 has been off one sample time.  This fixes some of the error between Profile and VC3000 brake run calculations.

  12. Fixed rounding error when displaying metric distance.

  13. Added factory default setup parameters.

 

2.05    12/09/2002

  1. Changed next calibrated date to last date calibrated.  Remove calibrated date display and printouts.  Unit information is now the only place last calibrated information is displayed.  Last calibrated date is set automatically when Gx calibration is performed.

  2. Date displays shows month as a 3 character alpha field.

  3. Display Avg. Gx on the first, after a programmed speed run.  Display END data at bottom of the table, for accel. Speed runs.

  4. Fixed countdown in acceleration mode.

  4. Host command, device type in battery command, supports Profile.
  5. Fix problem with setting factory threshold for brake meter.
  6. Brake Run, User type OT displays: AvgGy, PeakGx, PeakGy+-.
  7. Brake Run, User type OT printout: AvgGy, PeakGx, PeakGy+-.

    is set to different value from then the accelerometer zero calibration was done.

 

2.21    11/21/2005

  1. Added USB port to VC3000PC. Note VC3000PC must have FTDI part installed. Old VC3000PC
