TESTING
COMPONENT

A
Microwave Leakage Test 15.6
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 deflection, ●
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.
With any casework removed the leakage ●
should not exceed 5mW/cm².
Procedure
Add 275ml of cold water into a 600ml 15.6.1
microwave safe container.
Place the 600ml container in the centre of 15.6.2
oven and close the door.
Enter Service mode and select ‘Microwave 15.6.3
leakage test’ (A) from the oven tests.
Set the leakage meter to the appropriate 15.6.4
scale/range.
Move the survey meter probe across all 15.6.5
casework joins and vent areas including those
marked in yellow, shown opposite.
When the Magnetron circuit stops after 30 15.6.6
seconds, change the water and re-select the test to
continue.
Select the red ‘X’ on the display to stop the 15.6.7
test at any time.
Readings must be below 5mW/cm². If a level 15.6.8
greater than 5mW/cm² is observed, this should
be reported to Merrychef Service Department
immediately.
Notes should be kept of any leakage that 15.6.9
is observed in terms of the level and position on
the oven. This information should be kept with the
service documentation.
