The frequency, voltage or current range are selected in the original setup of the machine
for both sensory and motor functions and these will be indicated on the display together
with the actual amplitude of the stimulation being delivered to the patient.
In order to check that a probe is not faulty, a test facility is provided so that when the
thermocouple probe is touched on the Test Block a sounder will indicate that output is
present.
RF Power Section
This section consists of:-
2 large buttons- ‘Lesion’ and ‘Pulse’ each of which contains an integral green LED
1 Rotary Control- RF Output Control
2 pairs of up/down buttons for ‘Time/Count’ and ‘Set Temp’
2 other buttons-‘Auto Start’ and ‘Auto Stop’ (Red)
Pressing either of the large buttons selects that function and the green LED within the
button indicates that either ‘Lesion’ or ‘Pulse’ function has been selected. To select Pulse
Dose Mode the Pulse Button is pressed twice.
The RF Output Control knob is used to adjust the RF Power Output. If when either of
these functions is selected and the RF Output Control is not in its OFF position, no RF
Output will be delivered to the probe and a warning message will appear on the display.
The RF Output Control needs to be turned to the OFF position (fully anticlockwise) before
RF power can be applied. The green LED within the button will flash when power is being
applied.
In the ‘Lesion’ function the temperature and time for a Lesion are selected from the original
values set up in the machine, but both these values can be modified up or down using the
relevant up/down buttons.
