Calibrating the DriveRight 600

from the DriveRight 600
E
’s default of 4000 pulses per mile, or if the
vehicle’s pulses per mile are not known. VSS versions should be
calibrated using the speedometer (see “Calibrating Using the
Speedometer” on page 5), or by using the distance reading (see
“Calibrating Using Distance Readings” on page 7) or, if the vehicle’s
pulses per mile reading is known, can be calibrated using FMS.
DriveRight 600
E
OBD (# 8126OBD) requires no calibration because it
is installed in the vehicle’s On-Board Diagnostic (OBD) port. Select the
OBD installation method when you add a DriveRight 600
E
OBD to
DriveRight FMS.
Note: Enter the security code before calibrating the DriveRight 600
E
. See “Security
Code Screen” on page 16 for more information.
Calibrating the DriveRight 600
E
using FMS
Use FMS to accurately calibrate the DriveRight 600
E
VSS device,
provided you know the pulses per mile used by your vehicle’s VSS
(vehicle speed sensor). Contact your dealer’s service department for the
pulses per mile used by your vehicle’s VSS. Instructions on calibrating
the DriveRight 600
E
using FMS can be found in the FMS Online Help.
Calibrating Using the Speedometer
To calibrate using the DriveRight 600
E
’s speedometer, drive steadily at
40 km/h (25 mph) and press SET/CLEAR on the DriveRight 600
E
. The
DriveRight 600
E
bases its calibration on the speed of the vehicle at the
moment of calibration which it assumes to be 40 km/h (25 mph).
Because of the nature of this calibration procedure, Davis Instruments
strongly recommends that it be performed by two people: one to drive
the vehicle and one to operate the DriveRight 600
E
.
Note: If the security code is protected, enter the code number. The Calibration Screens
can not be accessed until the security code is entered.
1. Press and hold MODE to access the Settings Screens.
2. Enter the security code in the Security Code Screen.
3. Press and release MODE until the Calibration Screen displays.
The calibration speed (40 or 25) is located at the bottom right of the
display. The uncalibrated speed reading is located at the top of the
display, along with the unit of measure (km/h or mph). Until the
DriveRight 600
E
is calibrated, this speed reading will be inaccurate.
The distance, which appears in the lower left of the display, is not
necessary for this calibration procedure.
