single pulse rate instead of a range. The pulse rate is selected from a range of 1 to 200 Hz.
Selectable Polarity. Positive or Negative monophasic current may be selected. You may
also select both positive and negative and the current delivered alternates between the two
polarities.
Selectable Duty Cycle. Continuous or on/off duty cycles may be selected. The Dynatron
850plus and 550plus allow you to choose a muscle contraction/relaxation cycle from options
of 10/10 (ten seconds on and ten seconds off), 10/30, 10/50, or continuous cycle.
Selectable Ramp Speed. You can choose a ramp speed of 1/2 to 2-1/2 seconds in half-
second increments. For patient comfort, the ramp occurs both before and after the “On”
segment of the pulse.
Pulse Width. The pulse width is fixed at 25 µs.
Pulse Pair Interval. The interval between the two pulses in the wave form is fixed at 100 µs.
Intensity Display in Volts. The intensity display is shown in volts (peak voltage with no
load) with a range of 1 to 500.
