heard each time a stimulus is delivered.
•
Stimulus should occur at the set frequency. (1,2 or 5 Hz).
•
Use the adjusting wheel and slowly increase the current to 5.00mA.
•
Monitor that the stimulating waveform, measured and displayed in the diagnostic
window is square. The top part of the square wave should also touch the dotted line,
which represents the current setting as shown below.
