15.6 Microwave Leakage Test
Note before measuring.
¤ Make sure that the survey meter you are using
has been calibrated and is suitable for measuring
frequencies of 2,450 MHz.
¤ Do not exceed meter full scale defl ection,
leakage meter should initially be set to the
highest scale, then adjusted down as necessary
to ensure that low readings are measured on the
most sensitive range.
¤
To prevent false readings, hold the probe on the
grip provided and move at 2.5cm/second.
¤ Always hold the probe at right angles to the
oven and point of measurement, ensuring the
probe is reading 50mm from the test area.
¤
The leakage should not exceed 5mW/cm².
Procedure
15.6.1 Add 275ml of cold water into a 600ml
microwave safe container.
15.6.2 Place the 600ml container in the centre of oven
and close the door.
15.6.3 Enter Service mode and select ‘Microwave
leakage test’ (A) from the oven tests.
15.6.4 Set the leakage meter to the appropriate scale/
range.
15.6.5 Move the survey meter probe across all
casework joins and vent areas including those marked
in yellow, shown opposite.
15.6.6 When the Magnetron circuit stops after 30
seconds, change the water and re-select the test to
continue.
15.6.7 Select the red ‘X’ on the display to stop the test
at any time.
15.6.8 Readings must be below 5mW/cm². If a level
greater than 5mW/cm² is observed, this should
be reported to the Merrychef Service Department
immediately, and the oven should not be used.
15.6.9 Notes should be kept of any leakage that is
observed in terms of the level and position on the
oven. This information should be kept with the service
documentation.
