When "Analyzing" appears on the status window, the light bulb should glow; this does not
happen suddenly, but gradually (soft start).
Within a few seconds, the light bulb will gradually change from dark to fully bright.
– If not, but the lamp becomes immediately bright like switching on with a switch, replace
the board HF-42.
– If the light is not fully bright but dim and flickering, replace the triac (6).
If yes (O.K.), unplug the mains power plug and reconnect the power cables (1) to the
transformer (2).
Unplug the power plug and reconnect the cables (1).
When reconnecting the power cables (1), do not let these wires be close to the connectors for
the cables (4) and (5). Otherwise the high voltage can create sparks.
The cables (4) and (5) should be unscrewed from the transformer and placed away from it.
Mortal danger from electric shock
Exposed power contacts - High Voltage
After the generator starts the cable carries a voltage of about 7000 Volts!
– Plug in the mains power plug to power the analyzer.
A new analysis should be started. When "Analyzing" appears and the fuse is not damaged as
well as the mains power current didn't exceed 10 A (RMS), then the transformer is functioning
properly.
Otherwise, replace the transformer. The cables (4) and (5) are then reconnected.
If the problem still remains:
– Unplug the analyzer from the mains power.
– The cable (7) is unscrewed and removed from the capacitor (8)
After the generator starts (Analyzing) the cable (7) carries a voltage of about 7000 Volts! The
cable (7) therefore should be laid so that its end is at least 10 cm away from the nearest object!
If, after pressing START and after "Analyzing" appears, the breaker turns off, then replace the
rectifier (9).
Further causes could be found in the oscillator circuit
Because of the high voltage (7000 volts) and the high frequency (19.5 MHz), it is difficult to
make measurements without any special measuring instruments.
Thus, the analyzer needs to be turned off, and the power plug disconnected.
