2. MEASUREMENTS AND ADJUSTMENTS

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.

3. PROCEDURE FOR MEASURING MICROWAVE
ENERGY LEAKAGE
NOTE:
The U.S. Government standard is 5 mW/cm2 while in the customer’s
home. 2mW/cm2 stated here is our own voluntary standard. (1mW/cm2
for 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 2 for 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
