11.1. Adjustment of Safety switch A,
Safety switch B and short
switch
1. When mounting Safety switch A, Safety switch B and short
switch to door hook assembly, mount the Safety switch A,
Safety switch B and the short switch to the door hook
assembly as shown in table.
NOTE:
No specific adjustment during installation of Safety
switch A, Safety switch B and short switch to the
door hook is necessary.
2. When mounting the door hook assembly to the oven
assembly, adjust the door hook assembly by moving it in
the direction of arrow in table 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
components test procedures.
11.2. 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 accurate as possible.
1. Fill the beaker with exactly one liter of tap water. Stir the
water using the thermometer and record the beaker’s
temperature. (recorded as T1)
2. Place the beaker on the center of glass cook plate. Set the
oven for High power and heat it for exactly one minute.
3. Stir the water again and read the temperature of the beaker.
(recorded as T2)
4. The normal temperature rise (T2-T1) at High power position
for each model is as shown in table.
