4.4.2. Modes of operation
4.4.2.1. „MODE“ and „APPLICATOR“ keys
•
Pressing one of the 9 keys (S402 to 404, 406 to 408, 410 to 412) activates the assigned LED.
4.4.2.2. „+“ and „-“ keys, „MINUTES“ indicator
•
A short actuation of the „+“ key (S405) increments the treatment time indicator „MINUTES“
by 1 (end value 30).
•
Continuous actuation of the „+“ key increases the indicated time in steps of 5 digits (e. g. 5, 10,
15, etc. - end value 30).
•
The actuation of the „-“ key (S401) has the similar effect but the time indicated is reset (end
value 0).
•
Simultaneous actuation of both keys results in the indication of „0“
4.4.2.3. Power selector „INTENSITY“, indicators „WATTS“ and „TUNING“
•
Separate the coaxial plug connection X222 and connect the generator output to the test aerial or
50
Ω
precision resistor, respectively.
•
Check the indication of the power ranges:
3 W to 30 W
in
3
W steps
30 W to 80 W
in
5
W steps
80 W to 200 W
in 10
W steps
as well as the power range limits in dependence on the mode of operation and the applicator
selected in the following way.
•
Select „CW“ mode, „
DIPLODE
“ applicator and treatment time (> 0);
•
Turn the power selector (D408) by one click-stop detent to the right side;
•
„A“ must appear on the „MINUTES“ indicator for Tuning;
•
After switching over the indicator to treatment time the power of „9 W“ must be displayed, and
all LEDs of the bar indicator (VD401) are activated;
•
Check the power ranges by additional incrementing the power selector to the right;
•
Then set the power to „0“ by turning the power selector to the left side;
•
Repeat this prosedure in the CW mode of operation for all applicators where the initial values
after the tuning operation (9 W each) as well as the end values are to be checked:
coil-field electrode, small
30 W
coil-field electrode, medium
90 W
capacitor-field electrode, small
21 W
