SWIFT 40 Sensors Installing the Transducer 89
B. Rotate the tire as necessary, until the Fz on the axes icon (see the next
figure) printed on the transducer label is pointing up
C. Attach the level bracket so that it sits on top of the transducer. Insert the
locking pin through the bracket and into the pin pilot hole on the
transducer (see the next figure).
D. Place the digital inclinometer on the bracket and rotate the tire until the
inclinometer reads 0.0°, ±0.1° (or 90°, ±0.1° if the alternate position is
used).
E. Push the Angle Zero button on the front of the TI box. The Angle Zero
indicator will turn on for a few seconds, then turn off indicating that the
Angle Zero procedure is complete.
11. After completing the Bridge and Angle Zero procedures, rotate the wheel
one full revolution clockwise.
This allows the electronics to locate the index pulse for the encoder.
Note The wheel must rotate one-half revolution in the same direction and then
pass over the encoder index point before data collection is started.
12. Perform , “Verifying the Quality of the Zero Procedure,” on page 91.
13. Look at your data acquisition system to verify that the SWIFT sensor is
gathering data.
If Zero Algorithm=3
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.
