To align
Type II/Type III
wheel scanners, you use the horizontal alignment bar of the fixture.
Alignment is done by measuring from the bottom of the extended bar to the top of both ends of
the scanner mount. When both measurements are the same, alignment is correct. That is, as
shown below, when distance
A
is equal to distance
B
, alignment is correct.
Alignment must be performed when a new scanner is installed. Thereafter, unless the
scanner is damaged, it is unlikely that alignment will change once it has been set.
The transducer height bracket on the bottom of the alignment fixture can be used to ensure
proper installation of the transducers. When the transducer body touches the bracket, the
transducer body is 1-9/16 inches (3.97 centimeters) below the top of the rail and parallel to it.
3.2 2100-810NG Calibrated Heat Source
When a new scanner is installed, calibration is done. Thereafter, calibration usually is done
only when needed or on a regular basis during scheduled maintenance.
