Collecting Data
After you zero the TI, you are ready to collect data.
Note If you turn off power to the TI boxes, the zero values will remain valid, but
the encoder will need to find the index pulse to properly convert the
rotating coordinates to stationary coordinates. The transducer outputs
will not be correct until this happens.
1. Spin the wheel twice to ensure that the TI can identify the index pulse.
Spinning the wheel after you have completed the zero process will ensure
that the encoder is correctly referenced to the index pulse. Otherwise, the
data collected during the first revolution will be flawed.
2. Remove the vehicle from the lift or jacks.
3. Secure the connector that attaches the signal cable to the top of the slip ring
with high quality duct or electrical tape.
This will prevent dust, dirt, and water from entering the connector and
causing wear on the pins and sockets.
4. Perform a final inspection of the SWIFT sensor and the electronics to ensure
that everything is secure and the TI is on.
After the zeroing procedure, the settings are stored in non-volatile memory
in the TI box and will be retained when power is cycled. However, if the
environment temperature changes significantly, or the anti-rotate is
modified, rezeroing is recommended.
Note Rezeroing the transducer is good practice when thermal changes occur.
Rezeroing the transducer at conditions and temperatures closest to the
test conditions will provide a more accurate zero and reduce thermal
errors.
5. Turn on the data recorder.
6. Start data collection.
