Measurements and adjustments
Testing the high-voltage transformer
Attention
:
During cooking the high-voltage terminals of the transformer are under
a voltage of 2300 V~. When testing the transformer, keep your hands
and all measuring instruments, etc. away from these high-voltage
terminals.
♦
Switch off the appliance and discharge the capacitor with an insulated
screwdriver.
♦
Disconnect the connection lead of the capacitor from the terminal of the
high-voltage transformer.
♦
Connect the voltmeter to the filament terminals of the magnetron with a
toothed clamp and ensure that you always keep a good distance from
the voltmeter and the wires.
♦
Connect the appliance to the mains and start the cooking process. The
voltmeter must indicate a voltage of 3.3 V~.
Attention
:
Switch oft the appliance before disconnecting the voltmeter.
♦
If the measuring instrument does not indicate any voltage, you must set
the correct value and check whether a voltage of 220 V ~ (240 V) is
applied to the primary winding of the transformer during the cooking
process.
Anode voltage
For reasons of safety, it is neither advisable nor necessary to measure the anode voltage as the
appliance is under high voltage (approx. 4 KV).
