SWIFT 10 ATV Sensors

Road and Track Vehicles

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? The

typical value should be <100 N.

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 81.)

5. Perform a shunt calibration on each transducer.

Press the Shunt button on the front of the TI box (see the next figure), or use

the TI2SHUNT program.

The shunt indicators will toggle until the process completes. If the red failed

indicator lights, the shunt calibration has failed.

6. Verify that the outputs from the TI box matches those on the calibration

report.

Use either the TI2SHUNT or TI2XFER program to look at the shunt values

of the individual bridges.

The shunt calibration will fail if the measured shunt values are >2% (the

shunt tolerance) of the reference values that were set at the factory.

Typically, the shunt values will vary a maximum of 0.020-0.030 V from the

reference values.

Refer to the chapter, “Troubleshooting”, for more information on dealing

with shunt calibration failures.
