Calibration
Hardware Overview
Calibration
Each transducer is calibrated by MTS before shipment. The transducer and TI
may be returned to MTS for repair and recalibration as required.
Calibration is performed at MTS on a special fixture that is capable of applying
multiple loads to the transducer. During calibration, raw signals are measured.
The calibration gains and cross talk compensation values are computed from this
raw data. These gains are recorded in a calibration file.
A unique calibration file is supplied for each transducer. The serial number of the
TI associated with the transducer is listed at the top of the calibration file. A label
with the serial number of the TI box (and the SWIFT sensor with which it was
originally calibrated) is attached to the back of each TI box.
The calibration file is loaded into the TI non-volatile RAM by MTS before the
transducer is shipped. A copy of the file is also provided on a diskette.
MTS verifies the calibration by applying loads to the transducer, measuring the
main outputs and checking for accuracy. Final calibration reports are provided
with each transducer.
Shunt calibration
Shunt calibration information can be found in the SWIFT ® Mini Transducer
Interface product manual, part number 100-214-316.
