Vehicle Setup ..
Use this menu item to calibrate all Distance Gauges. This calib
ration also directly affects th
e accuracy of all Speed, MPG an
DTE gauges. This calibration is especially necessary for
vehicles which no longer have the stock wheels, tire sizes,
transmission, or rear-end differential..
This calibration will also comp
ensate for inaccuracies in
stock speed sensor and the
vehicle’s distance measurement system.
Perform this Calibration prior to all other calibrations.
To perform the distance calibration follow this procedure:
Align front tire with
first mile marker
Reset the trip gauges:
Zero All Trip
Travel to the next mile marker, aligning the front tire to the mile marker
Change the value shown to 1.00 miles
, using the
to save and set the calibration
Once saved, the calibration factor will be displayed at the bottom of the display.
Many roads will have mile markers, but avoid roads that are
not straight. Generally more markers will improve accuracy.
greater your speed
between mile markers the better the
accuracy of the distance calibration
If you chose to travel several mile markers, then enter in
the number of miles actually driv
en, for example, 3.00 miles.
Unplugging UltraGauge after calibra
tion will not cause loss of calibration.
Using the vehicle’s odometer to perf
orm this calibration is po
intless since the odometer and UltraGauge receive
distance information from the same source.
Here is what the manual states...good Luck.
