MEASUREMENT OF THE MICROWAVE OUTPUT POWER

Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed to the microwave as directed below.

PROCEDURE

  1. Microwave power output measurement is made with the microwave oven supplied at rated voltage and operated at its maximum microwave power setting with a load of 1,000¡ 5cc of potable water.

  2. The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190 mm.

  3. The oven and the empty vessel are at ambient temperature prior to the start of the test.
    The initial temperature of the water is 10¡ 2˚C (50¡ 3.6˚F).
    It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf which is in the lowest normal position.

  4. Microwave power is switched on.

  5. Heating time should be exactly 49 seconds.
    Heating time is measured while the microwave generator is operating at full power.
    The filament heat-up time for magnetrons is not included.

  6. The initial and final water temperatures are selected so that the maximum difference between the ambient and final water temperatures is 5K.

  7. The microwave power output P in watts is calculated from the following formula:

• ∆T is actual temperature rise.
• t is the heating time.
The power measured should be 600W¡ 10.0%.

CAUTION :

  1. Water load should be measured exactly to 1 liters.
  2. Input power voltage should be exactly 230V as specified.
  3. Ambient temperature should be 20¡ 2˚C(68¡ 3.6˚F)

MICROWAVE RADIATION TEST

WARNING

  • Make sure to check the microwave leakage before and after repair of adjustment.
  • Always, start measuring of an unknown field to assure safety for operating personnel from microwave energy.
  • Do not place your hands into any suspected microwave radiation field unless the safe density level is known.
  • Care should be taken not to place the eyes in direct line with the source of microwave energy.
  • Slowly approach the unit under test until the radiometer reads an appreciable microwave leakage from the unit under the test.

PROCEDURE
A) Prepare Microwave Energy Survey Meter, 600cc glass beaker, glass thermometer 100˚C or 212˚F.
B) Pour 275cc¡ 15cc of tap water initially at 20¡ 5˚C(68¡ 9˚F) in the 600cc beaker with an inside diameter of approx. 9.5cm (3.5 in).
C) Place it at the center of the tray and set it in a cavity.
D) Close the door and operate the oven.
E) Measure the leakage by using microwave energy survery meter with dual ranges, set to 2450 MHz.
ƒ¡ Measured radiation leakage must not exceed the values prescribed below.
• Leakage for a fully assembled oven with door normally closed must be less than 4mW/cm2.
ƒ¡When measuring the leakage, always use the 2 in (5cm) space cone with probe. Hold the probe perpendicular to the cabinet and door. Place the space cone of the probe on the door, cabinet, door seam, door viewing screen, the exhaust air vents and the suction air vents.
ƒ¡Measuring should be in a counter-clockwise direc- tion at a rate of 1 inch/sec. If the leakage of the cabinet door seam is unknow, move the probe more slowly.

ƒ¡When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe end at the base of the cone does not get closer than 2 inches from any metal.
If it does, erroneous reading may result.

CIRCUIT DESCRIPTION

1. When the food is placed in the oven cavity and door is closed.

  • The contact of the interlock monitor switch open.
  • The contacts of the primary interlock switch and secondary interlock switch close.

2. When the timer is set to the time desired.

  • The contact of the timer switch close.
  • Oven lamp turn on.
  • 120V AC is applied to the high voltage transformer.
  • Turntable motor start rotating and glass tray rotating.
  • Fan motor rotating and cools the magnetron by blowing air.
  • Timer motor operating and point to passing cooking time.
  • 3.3 Volts AC is generated from the filament winding of the high voltage transformer. This filament voltage is applied to the magnetron to heat the magnetron filament through two noise preventing choke coils.
  • A high voltage of 2000 Volts AC is generated in the secondary of high voltage transformer and this secondary voltage is increased by the action of the diode and the charging of the high voltage capacitor. This resultant D.C voltage is then applied to the anode of the magnetron. As shown in Fig. 2 the first half cycle of the high voltage produces in the high voltage transformer secondary charges the high voltage capacitor. Current flow is in the direction of the dotted-line during the second half cycle, the voltage produced by the transformer secondary, and the charge of the high voltage capacitor are combined and applied to the magnetron as shown by the solid line so that oscillations begins. The disturbance wave generated by the magnetron is prevented by the choke coils of 1.5µH, filter capacitors of 500pF and the magnetron’s shielded case so that TV and radio programs are not impaired by noise.

3. When the door is opened during cooking.

  • Primary interlock switch and secondary interlock switch open to cut off the primary voltage to the high voltage transformer to stop microwave oscillation.
  • Fan motor, timer motor and turntable motor stop rotating.
  • Oven lamp turn off.
  • As soon as the door is opened, monitor switch close (NC) to create the short circuit.
    If the contacts of primary interlock switch and secondary interlock switch are both malfunction, the 15A fuse blows open due to the large current surge caused by monitor switch activation.
