Depending on the step of the respective Individualized Microcurrent Frequency (IMF) program, the Healy device either performs a new frequency analysis every 10 seconds (Realtime) or analyzes three frequencies in the steps, Resonance (from a frequency band) and Selection (from a pool of frequencies carefully selected by an expert). Afterwards, the progress is analyzed every 10 seconds until 95% is reached for the respective frequency.
