12.1. Adjustment of primary latch
switch, door switch and short
switch.
1. Mount the Primary latch switch, the door switch and the
short switch to the door hook assembly as shown in ILL.
NOTE:
No specific individual adjustment during installation
of the Primary latch switch, door switch or short
switch to the door hook are required.
2. When mounting the door hook assembly to the oven
assembly, adjust the door hook assembly by moving it in
the direction of the arrows in the illustration, so that the
oven door will not have any play in it. Check for play in the
door by pulling the door assembly. Make sure that the latch
keys move smoothly after
adjustment is completed.
Completely tighten the screws holding the door hook
assembly to the oven assembly.
3. Reconnect the short switch and check the continuity of the
monitor circuit and all latch switches again by following the
component test procedures on P.21.
12.2. 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 liter beaker *Glass thermometer
*Wrist watch or stopwatch
NOTE:
Check the line voltage under load.Low voltage will
lower the magnetron output. Take the temperature
readings and heating time as accurately as possible.
1. Fill the beaker with exactly one liter of tap water.Stir the
water using the thermometer and record the water’s
temperature. (recorded as T1).
2. Place the beaker on the center of glass tray.
Set the oven for High power and heat it for exactly one
minute.
3. Stir the water again and read the temperature of the water.
(recorded as T2).
4. The normal temperature rise at High power level for each
model, is as shown in table.
