MICROWAVE MEASUREMENT PROCEDURE

A. Requirements:

1)Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven should not exceed 1mW/cm2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm2 at any point 5cm or more from the external surface of the oven.

2)Safety interlock switches Primary interlock relay and door sensing switch shall prevent microwave radiation emission in excess of the requirement as above mentioned, secondary interlock switch shall prevent microwave radiation emission in excess of 5 mW/cm2 at any point 5cm or more from the external surface of the oven.

B. Preparation for testing:

Before beginning the actual measurement of leakage, proceed as follows:

1) Make sure that the actual instrument is operating normally as specified in its instruction booklet.

Important:

Survey instruments that comply with the requirement for instrumentation as prescribed by the performance standard for microwave ovens, 21 CFR 1030.10(c)(3)(i), must be used for testing.

2)Place the oven tray in the oven cavity.

3)Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5˚C (68˚F) in the center of the oven cavity.

The water container shall be a low form of 600 ml (20 oz) beaker with an inside diameter of approx. 8.5 cm (3-1/2 in.) and made of an electrically nonconductive material such as glass or plastic.

The placing of this standard load in the oven is important not only to protect the oven, but also to insure that any leakage is measured accurately.

4)Set the cooking control on Full Power Cooking Mode.

5)Close the door and select a cook cycle of several minutes. If the water begins to boil before the survey is completed, replace it with 275 ml of cool water.

C. Leakage test:

Closed-door leakage test (microwave measurement)

1)Grasp the probe of the survey instrument and hold it perpendicular to the gap between the door and the body of the oven.

2)Move the probe slowly, not faster than 1 in./sec. (2.5 cm/sec.) along the gap, watching for the maximum indication on the meter.

3)Check for leakage at the door screen, sheet metal seams and other accessible positions where the continuity of the metal has been breached (eg., around the switches, indicator, and vents).

While testing for leakage around the door pull the door away from the front of the oven as far as is permitted by the closed latch assembly.

4)Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm2, and that the secondary interlock switch does turn the oven OFF before any door movement.

NOTE: After servicing, record data on service invoice and microwave leakage report.

R-530EK specifications

The Sharp R-530EK is a notable microwave oven that combines functionality with innovation to enhance cooking convenience. With a sleek design and user-friendly interface, this model has earned a place in many kitchens around the globe.

One of the primary features of the Sharp R-530EK is its powerful microwave output. The oven boasts a maximum power of 900 watts, ensuring that food can be heated quickly and evenly. This power level allows users to prepare a variety of meals, from reheating leftovers to cooking dishes from scratch, in significantly less time than traditional cooking methods.

The R-530EK is equipped with a spacious interior, offering 25 liters of capacity. This ample space allows for cooking larger dishes or multiple servings at once. The turntable design ensures even cooking by rotating food during the heating process, further enhancing the microwave's efficiency.

Another standout feature of the Sharp R-530EK is its array of pre-programmed auto-cook menus. These presets simplify cooking by providing specific times and power levels for various types of food, including popcorn, pizzas, and oatmeal. Users can simply select the appropriate setting, and the microwave takes care of the rest, making it ideal for those who may not have extensive cooking experience.

The microwave utilizes advanced inverter technology, a feature that sets it apart from many conventional microwave ovens. Inverter technology allows for continuous and consistent power output, providing more precise temperature control. This means that delicate foods such as seafood or chocolate can be heated without the risk of overcooking or burning, resulting in better texture and flavor.

Additionally, the R-530EK is designed with multiple cooking functions that enhance its versatility. These include defrosting capabilities, grilling options, and even signals indicating the completion of cooking cycles. The easy-to-read digital display and intuitively designed buttons contribute to the overall user experience, making it accessible for individuals of all ages.

Moreover, this microwave oven ensures safety with features such as a child lock, which prevents accidental operation by little hands. The Sharp R-530EK is both an efficient and reliable addition to any kitchen, embodying the perfect blend of cutting-edge technology and practical design to meet the demands of modern cooking. With its impressive range of features and performance capabilities, it stands as a valuable tool for aspiring chefs and busy families alike.
