6-lug wheels are measured like 4-lug wheels. Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.. Note: When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured using a bolt pattern gauge. A bolt pattern gauge is a specialty tool and is not widely available.
Palpation should be done using the fingertips and intensity of the pulse graded on a scale of 0 to 4 +:0 indicating no palpable pulse; 1 + indicating a faint, but detectable pulse; 2 + suggesting a slightly more diminished pulse than normal; 3 + is a normal pulse; and 4 + indicating a bounding pulse.
Pulsed Light delivers wavelengths from 500 to 1200 nm while Laser can deliver only 1 wavelength at a time. Pulsed Light can deliver total pulse durations up to 25 msec or 1235 msec while most Laser can deliver pulse durations up to 40-100msec (and 1 machine can deliver 1000 msec but at only 800nm) Pulsed Light's larger light beam size allows for faster treatment and deeper light penetration.
