ABSTRACT:
An automatic testing system for electric nerve stimulator units is described wherein a digital computer controller utilizing programmable read only memory is used to control testing transcutaneous electrical nerve stimulator (TENS) units, such tests being conducted by sensing the output pulses from the stimulator under test and processing the output pulse signal information by circuit means under the control of the computer resulting in digital readouts of the peak output voltage, width and rate of the output pulses of the stimulator. The load impedance and quantity of delivered pulse charge for a patient can also be determined as digital readouts and indications of the pulse polarity and/or bipolarity is displayed.
