a) Switch the unit OFF.

b) Place F2 fuse (4A T type) in its fuse-holder.

c) Set vertical sensibility of the oscilloscope at 20V/div (DC mode).

d) Switch the ON unit and check that on test point TP3, when mains is 230V, voltage is 71÷78 V

e) Switch the unit OFF and remove the F2 fuse.

C) RADIO-FREQUENCY SECTION

1) W ORK FREQUENCY CHECK (TP4)

a) Connect the frequency-meter on test point TP4.b) Switch the unit ON and ckeck that frequency is 950 kHz (± 10 kHz).

c) Activate the unit and check the following waveform:

[TP4]

2) R AMP CALIBRATION (TP5, R7)

a) With the selector mode on 'CUT' and the unit activated, adjust R7 trimmer in order to obtain a waveform on TP5 like the

following:

3) DEAD TIME CALIBRATION (TP6,TP7, R7)

a) Turn power control potentiometer 'POWER' all clockwise (MAX).

b) Connect the probe '1' on TP6 and the probe '2' on TP7.

c) With the unit activated, set trimmer R7 in order to obtain a dead time (when both signals are on ZERO) equal to 150ns.

4) C OAGULATION PERIOD CHECK (TP8)

a) Set the selector mode on 'BLEND CUT'.

b) Set the potentiometer for power level adjustment all counterclockwise (MIN).

5) HF OUTPUT AMPLIFIER CHECK (TP9, TP10)

a) Switch OFF the unit.

b) Place F2 fuse in its fuse-holder.

c) Connect a 500 ohms non-inductive load to the output sockets.

d) Set the functions selection on 'PURE CUT'.

e) Turn all clockwise power control (MAX).

f) Switch ON and activate the unit.

g) Check the following waveforms:

6) C URRENT LIMITATION CALIBRATION (R36)

a) Connect to the output sockets ('MONO') a non-inductive 50 ohms load

b) Switch ON and activate (by pedal) the unit

c) Turn 'R36' trimmer in order to obtain a delivered current of 0.8 Amps

Check if the unit withstand short-circuits. To avoid a damage in the unit, this check must be done for few seconds only.7) C ALIBRATION OF REVERSE FEEDBACK LEVEL( TP11, R24)
