GSP9700 Series Road Force Measurement System Operation
Performing a StraightTrak
Mount the tire/wheel assembly centered on the shaft of the GSP9700. Use care to
make sure the wing nut is well tightened.
Choose the appropriate balancing procedure for the particular type of rim
construction.
Check the tire pressure. Inflation Station will automatically inflate or deflate the tire to
the preset air pressure. When the tire pressure is correct, the tire graphic on the
screen will turn green.
If tire pressure is not checked before load roller application, an auto prompt for the
Inflation Station will appear.
NOTE: Lateral force varies significantly with tire inflation pressure.
For accurate results, it is important that the inflation pressure
for each tire is set to the correct value.
Enter rim dimensions by using the inner and outer Dataset arms.
If using a balancing procedure other than the standard clip-on/clip-on weight,
®
StraightTrak Lateral Force Measurement will prompt the operator to measure the
inner and outer rim locations to establish wheel offset to the roller. This is a baseline
measurement necessary for the StraightTrak
inner and outer Dataset arms to measure the rim locations.
Close safety hood.
Press the green "START" button if "Hood Autostart" is disabled.
