SWIFT 40 Sensors Installing the Transducer

Verifying the Quality of the Zero Procedure

Perform the following consistency checks for each SWIFT sensor while the

vehicle (or corner) is elevated.

1. Does Fz measure the approximate weight of the tire/rim assembly?

2. Is Fx small (less than 0.1% of the rated load)?

3. What is the variance in Fz (modulation) when the tire is slowly rotated?

4. When the vehicle is on the ground, is the Fz reading approximately equal to

the corner weight of the vehicle? (See, “Effect of Zero Reference on SWIFT

Output,” on page 92.)

5. Perform a Shunt calibration on each transducer.

A. Elevate the vehicle on a lift, or jack up each corner.

B. Connect the shunt calibration cables from the Shunt A, Shunt B

connectors on the front of the transducer to the Shunt A, Shunt B

connectors on the back of the TI box (see the next figure).

C. Connect the signal cable from the slip ring to the Slip Ring connector

on the back of the TI box.
