OPERATION
Premodulated
Premodulated is an amplitude modulated sine wave. This waveform is similar to the beat
frequency created by Interferential current. In some cases, Premodulated therapy provides a
good alternative for Interferential treatment especially when treating areas of the body where
four electrodes can not be utilized.
Cycle Time
parameter controls the on/off cycle time of the current. There are 2 available
options, Continuous (default) and 5/5.
When you highlight
Beat Frequency
and press the
enter
button, 5 options are displayed.
They are 1-10 Hz, 80-150 Hz (default), 1-150 Hz, Variable and Fixed.
The
Variable
option allows you to select a Low Beat frequency from 1-200 Hz and a High Beat
frequency from 1-200 Hz. To make changes in the Variable frequency, highlight
variable
and
press the
enter
button. To change the Beat Low frequency, use the
down
arrow to highlight
Beat Low and press
enter
.
Use the
up
/
down
arrows to adjust the frequency. Press
enter
to
accept.
Beat Low
describes the lowest frequency in the range of a sweep mode. For example when
using a sweep of 80-150 Hz, 80 Hz is the lowest frequency.
Beat High
describes the highest frequency in the range of a sweep mode. For example when
using a sweep of 80-150 Hz, 150 Hz is the highest frequency.
The
Fixed Option
, allows you to select a fixed frequency from 1-200 Hz. To make changes to
the
Fixed frequency, highlight
fixed
and press
enter
. Use the
up
/
