Calibration Procedure
Place the probe or electrodes. Start the calibration. Ask the patient to make a sustained contraction (the gauges change automatically), then release for a few seconds. The BioStim automatically adjusts the operating range. If the base tone is too high, check the box labelled "Zero relative". Click the arrow to move on to the next page (or wait until the end of the calibration period). While the exercise is underway, the settings may still be adjusted manually with the + and - buttons in the top right of the screen.
