8. MEASUREMENTS AND ADJUSTMENTS

8.1 Installation of primary latch switch, sec-
ondary latch switch and short switch
1. When mounting primary latch switch, secondary latch
switch and short switch to door hook assembly, mount
the primary latch switch, the secondary latch switch and
the short switch to the door hook assembly as shown in
the illustration.
NOTE: No specific adjustment during installation of primary
latch switch, secondary latch switch and short switch
to the door hook is necessary.
8.2 Measurement of microwave output
The output power of the magnetron can be determined by
performing IEC standard test procedures. However, due to
the complexity of IEC test procedures, it is recommended to
test the magnetron using the simple method outlined below.
Necessary equipment:
• 1 Iitre beaker
• Glass thermometer
• Wrist watch or stopwatch.
NOTE: Check the line voltage under load to ensure it
meets specifications. Low voltage will cause
reduction in the magnetron output. Temperature
readings and heating time should be as accurate
as possible.
Output power performance test procedure
1. Fill the beaker with exactly one litre of tap water. Stir the
water using the thermometer and note the temperature
(record as T1)
2. Place the beaker on the centre of glass cook plate.
3. Set to high power and heat for exactly one minute.
4. Stir the water again with the thermometer and note the
temperature (record as T2).
5. The normal temperature rise (T1-T2), should be more
than 7.0˚C using the high power selection with the oven
operating at specified line voltage.
