Controlling a TENS (muscle stimulator) device - Device Hacking - Arduino Forum

I have a Promed TENS 1000 S dual-channel muscle stimulation device which I want to be able to control from a microcontroller. It has 3 potentiometers: #1 pulse width (30µs - 260µs) #2 pulse frequency (2Hz - 150 Hz) #3 pulse strength (0V - ~80V) -> current goes up to 80mA at 80V #1 and #2 are low-signal potentiometers meant to inform the chip how to model its PWM output. I am planning to replace these with a two-channel digital potentiometer and I don't have any questions about this yet. #
