Testing ST700 Dash Display System
60
TESTING
After you have installed and set–up the system as described in this man-
ual, you should test it to make certain all the sensors, displays and alarm
functions work correctly:
1. Switch on the vehicle ignition and check that the ST700 Dash Dis-
play System initialises correctly as described on page 31.
2. Start the engine and let it warm at idling speed. Check that the
tachometer display shows the correct reading for the engine idling
speed. If the tachometer shows a value that is completely wrong,
you may have set the engine cylinders incorrectly. Refer to page 53
for instructions to set the number of cylinders.
3. Accelerate to a constant, safe speed, and time the vehicle between
two markers whose separation distance you know. Calculate the
vehicle speed and confirm that it is as shown by the ST700 Dash
Display System. Any difference between the actual vehicle speed
and the displayed value could be caused by one of two factors:
❑ You have set the Wheel Pulses parameter incorrectly. Refer to
page 54 for instructions to set the wheel pulses.
❑ You have measured or set the Wheel Circumference parameter
incorrectly. Refer to page 54 for instructions to set the wheel cir-
cumference.
