Interferential 4-pole set-up (960 and 970)
Interferential 4-pole therapy (IFT4) always uses both output channels A and
B. Operating the rotary dial will increment both A and B outputs together.
‘Carrier’: Touching this button selects 4, 8 or 2 kHz carrier frequency.
‘AMF’ (Amplitude Modulation Frequency): Touching this button opens the
AMF window.
The amplitude modulation frequency (AMF), or beat frequency, is set as a
Base and Peak beat frequency. The beat frequency sweeps between the
base and the peak frequency at a rate determined by the setting of the
Pattern button. If the base and peak frequencies are set to the same value,
then a constant beat frequency is produced. The Base and Peak
frequencies may be set in 1 Hz increments from 0 to 250 Hz. Touch ‘OK’
when the desired frequencies have been chosen to return to the
Interferential 4-pole set-up screen.
