Microwave leak test
This test is to be
performed
after every type of maintenance work on the door, closing device,
microswitches and magnetron.
Test equipment
•
600 ml glass beaker
•
Microwave measuring instrument
Test procedure
Pour 250 ml of water into the beaker and then place this in the centre of the microwave oven.
Switch on the microwave oven. Set it to 5 minutes at the maximum power level.
Hold the test sensor of the microwave measuring instrument vertical to the door edge of the appliance
and slowly move it along.
The following areas must be tested for microwave leaks:
•
Door and control section
•
All ventilation slits
•
All folded joints
•
Weld on the underside
•
Base plate
Procedure:
•
Open the door just so much that the appliance is not switched off.
•
The distance between the door and the sensor must not be less than 5 cm.
•
The maximum admissible radiation leak is 4 mW / cm².
Checking the diode:
Normal result:
Create a circuit with 12 V DC and a 2.5 V lamp between
the connections.
The lamp is either on or off, depending on
the direction of current
Abnormal result:
