Controlling Stimulation Amplitude

Stimulation output ranges 

 

Maximum stimulation current is dependent on the stimulation settings and impedance values. In the event of high 

impedances values or high frequency and pulse width, the output stimulation amplitude may be less than the programmed 

stimulation amplitude. Typical settings are 14 Hz and 210 us with impedance from 600 – 1500 Ohms.

Impedances below 400 is considered a short circuit and impedances above 6000 is 

considered an open circuit. 

 

If the stimulator is delivering less current than programmed on the CP, when stimulation is active the blue number above the 

stimulation bar shows the actual delivered stimulation current. 

 

If stimulation amplitude is being adjusted and no change in patient response is observed, the user should compare the 

delivered current (blue display above the stimulation bar when stimulation is on) to the programmed current (gray display 

above the stimulation bar when stimulation is off) to determine if the system is delivering the programmed current.
