Threshold Start Max 2500.0 mV
Min 0.0000 mV The voltage of the threshold at the first threshold point . This point is where the
blanking distance ends .
Threshold Middle Max 2500.0 mV
Min 0.0000 mV The voltage of the threshold at the middle threshold point
Threshold End Max 2500.0 mV
Min 0.0000 mV The voltage of the threshold at the last threshold point . This point is at the Empty
Distance .
