2.1. Adjustment of primary latch
switch, secondary latch switch
and short switch.
1. Mount the Primary latch switch, the Secondary latch switch
and the Short switch to the door hook assembly as shown
in ILL.
NOTE:
No specific individual adjustments during
installation of the Primary latch switch, Secondary
latch 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.
2.2. 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.

NOTE:
The U.S. Government standard is 5 mW/cm2while in the
customer’s home. 2mW/cm2stated here is our own
voluntary standard. (1mW/cm2for Canada)
3.1. Equipment
• • •
• Electromagnatic radiation monitor
• • •
• Glass thermometer 212°F or 100°C
• • •
• 600cc glass beaker
3.2. Procedure for measuring
radiation leakage
Note before measuring.
• • •
• Do not exceed meter full scale deflection. Leakage monitor
should initially be set to the highest scale.
• • •
• To prevent false readings the test probe should be held by
the grip portion of the handle only and moved along the
shaded area in Figure no faster than 1 inch/sec
(2.5cm/sec).
• • •
• Leakage with the outer panel removed ...... less than
5mW/cm2.
• • •
• Leakage for a fully assembled oven with door normally
closed ...... less than 2mW/cm 2(1mW/cm 2for Canada).
• • •
• Leakage for a fully assembled oven [Before the latch switch
(primary) is interrupted] while pulling the door ...... less than
2mW/cm 2.
1. Pour 275 ± 15cc (9ozss± 1/2oz) of 20°C ± 5°C (68° ± 9°F)
water in a beaker which is graduated to 600cc, and place in
the center of the oven.
2. Set the radiation monitor to 2450MHz and use it following
the manufacturer´s recommended test procedure to assure
correct results.
3. When measuring the leakage, always use the 2 inch (5cm)
spacer supplied with the probe.
4. Tap the start pad or set the timer and with the magnetron
oscillating, measure the leakage by holding the probe
perpendicular to the surface being measured.
3.2.1. Measurement with the outer panel
removed.
Whenever you replace the magnetron, measure for radiation
leakage before the outer panel is installed and after all
necessary components are replaced or adjusted. Special care
should be taken in measuring around the magnetron.
3.2.2. Measurements with a fully
assembled oven.
After all components, including outer panel are fully assembled,
measure for radiation leakage around the door periphery, the
door viewing window, the exhaust opening and air inlet
openings.
3.3. Record keeping and
notification after measurement
• • •
• After any adjustment or repair to a microwave oven, a
leakage reading must be taken. Record this leakage
reading on the repair ticket even if it is zero.
A copy of this repair ticket and the microwave leakage
reading should be kept by repair facility.
• • •
• Should the radiation leakage be more than 2 mW/cm2
(1mW/cm for Canada) after determining that all parts are in
good condition, functioning properly, and genuine
replacement parts as listed in this manual have been used,
immediately notify PASC, PSC or PCI.
3.4. At least once a year, have the
radiation monitor checked for
calibration by its
manufacturer.
