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

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.

NOTE:

The U.S. Government standard is 5 mW/cm customer’s home. 2mW/cm voluntary standard. (1mW/cm

stated here is our own

for Canada)

while in the

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/cm

•

Leakage for a fully assembled oven with door normally

• •

closed ...... less than 2mW/cm

•

Leakage for a fully assembled oven [Before the latch switch

• •

(primary) is interrupted] while pulling the door ...... less than

2mW/cm

1. Pour 275 ± 15cc (9ozs

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 recomm ended 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.

(1mW/cm2for Canada).

± 1/2oz) of 20°C ± 5°C (68° ± 9°F)

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/cm

• •

(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.
