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.
A 'typical' HVPC set of parameters are illustrated in Figure 2 below. In this case the pulse duration is set at 200Âµs, the interpulse interval is set at 9800Âµs and therefore 1 cycle will take 10000Âµs to deliver (which is 10ms-milliseconds). If 1 cycle takes 10ms to deliver, the stimulation frequency will be 100Hz.t is argued (see figure 3 below, from www.nervestudy.com) that although the pulses are high voltage (typically 150-500V), they are of very short duration (microsec) and thus the actual (averaged) current flow through the tissues will be low-in the microcurrent range (microamps).
