The AngleOffset value is
incorrect in the calibration
file.
If an incorrect AngleOffset value is set in the TI
calibration file, an axis which should have no
load may show some load from another vehicle
coordinate axis based on the incorrect reference
orientation. Verify that the correct AngleOffset
is set for your specific application (refer to
Excessive noise during the
zero procedure caused an
incorrect bridge zero, or the
angle computation to be
calculated incorrectly.
Electrical Noise: The transducer has power
conditioning, shielded cables and on-board
amplification to reduce electrical noise.
However, if the TI or transducer are very near a
powerful noise source, some noise can be
picked up with the signal.
Check that the TI electronics are grounded
properly through the power cable to the power
source. If possible, perform the zeroing and
shunt calibration procedure away from the noise
source.
Physical Noise: If the transducer is part of an
assembly that is connected to active hydraulics
or other assemblies that may experience
physical vibrations, these vibrations may be
picked up as inertial forces read by the
transducer. Check that the transducer is not
experiencing dynamic loading or vibrations
during the zero process or shunt calibration.
Output levels are much
higher or lower than
expected
Gains in the TI calibration
file have been overwritten
or modified.
Use the TI2XFER program to upload the
current TI calibration file (refer to
on page 47). Check that the
gain settings match the original calibration file
sent with the transducer. If they are different,
download the original file to the TI, and make
any mode changes needed for your specific
application.
Do not make changes to the original
calibration file on the disk.
Changing the original file means you will
lose the original calibration data for your
transducer.
Make a copy of the original file and make any
changes to the copy.
