A measure of whether each PEMF pulse lasts long enough for the magnetic field to fully build to its intended peak strength. Every coil takes a certain amount of time for the current (and therefore the field) to ramp up fully. If the pulse ends too soon, the field never reaches its full potential. The device is underperforming even though it appears to be working normally. Pulse completeness is expressed as a percentage. 100% means the pulse is exactly long enough for full field buildup. Values above 100% confirm the field had time to fully develop. Values significantly below 100% indicate the pulse is being cut short.
Coil current does not switch on instantly; it builds up along this curve, set by the coil's L/R time constant. It reaches about 63% of full after one time constant, 95% after three, and 99% after five. If the pulse is at least about three time constants long, the current has essentially finished building, so the pulse is complete.
