Test Track Vehicle

Installing the Transducer

I.

Place the digital inclinometer on the bracket and rotate the tire until the

inclinometer reads 0.0°, ±0.1° (or 90.0°, ±0.1° if the alternate position
is used).

J.

Push the Angle Zero button on the front of the TI box. The Angle Zero

indicator will light for a few seconds, then both the Bridge Zero and
Angle Zero indicators should turn off.

Note

If the red Fail indicator lights momentarily and the Bridge Zero and
Angle Zero indicators end up blinking slowly, problems were detected
with the zero. Try repeating the procedure. Use TISTATUS for a more
detailed explanation of the problem. If you continue to have an error,
consult the chapter

, “Troubleshooting,”

on page 127.

K. Rotate the transducer slightly to update the rotational transformation.

At this point the TI should be reading absolute forces in the vehicle
coordinate system.

L.

Perform

, “Verifying the Quality of the Zero Procedure,”

on page 95.

M. Look at your data acquisition system to verify that the SWIFT sensor is

gathering data.

If Zero Algorithm=1

When you zero the TI, you want the vehicle to be fairly level and the transducer
to be as close to plumb as practical.

1. Install the SWIFT sensor(s) and data collection equipment on the vehicle.

2. Connect all cables and turn on the power to the TI boxes.

3. Let the TI boxes and transducers warm up for 15-20 minutes.
