Calibrating the DriveRight 600E

Be aware that the DriveRight 600E responds to changes in speed

faster than most vehicles’ speedometers. To accurately compare,

drive steadily at one speed for a short time.

8. Fine tune the calibration by pressing PLUS or MINUS.

Each time PLUS or MINUS is pressed, the DriveRight 600E speed

reading adjusts up or down. Depending on the speed of the vehicle

and the calibration, a change in the speed reading in the Calibration

Screen may or may not display each time a button is pressed.

Note: Pressing and holding PLUS or MINUS increases the rate at which the DriveRight

600E adjusts the speed reading.

9. Continue to press PLUS or MINUS until the DriveRight 600E’s

speed reading agrees with the vehicle’s speedometer at a variety of

speeds.

10. When you are finished calibrating, press and hold MODE until the

Current Readings Screen displays. All calibration information is

automatically saved.

Note: Do not press and hold SET/CLEAR in an effort to save the fine-tuned calibration.

The DriveRight 600E resets the calibration number if SET/CLEAR is pressed.

Calibrating Using Distance Readings

To calibrate using the vehicle’s distance reading instead of its speed

readings, compare a distance reading taken from the vehicle’s odometer

to the DriveRight 600

E distance reading and adjust the DriveRight

600

E to match the vehicle’s odometer.

Note: Davis Instruments recommends that you drive a minimum of 32km (20 miles)

when calibrating the DriveRight 600E using its distance reading.

The vehicle’s speedometer and odometer may not be perfectly linked.

If the two readings differ and the DriveRight 600

E has been calibrated

using the vehicle’s odometer, a discrepancy between the DriveRight

600

E’s speed readings and the vehicle’s speedometer may exist.

1. Obtain a rough calibration, using the speedometer as described in

“Calibrating Using the Speedometer” on page 5.

2. Reset the vehicle’s trip meter to zero or note the odometer reading.

3. Start a new trip on the DriveRight 600E (i.e., the distance traveled is

0) and make sure the Current Readings Screen is being displayed.

To forcibly start a new trip, log out (see page 11 for details).

4. Drive the vehicle for at least 32 km (20 miles). The calibration

becomes more accurate the further the vehicle is driven.
