How to Measure a TurboChef Rapid Cook Oven for RF Leakage

If there’s a leakage present, or even suspected, it’s important that it be measured and repaired. These instructions will show you how to measure a TurboChef Rapid Cook oven for RF leakage with ease.

Measuring RF Leakage for Optimal Microwave Safety

• Step 1. Turn the oven on and allow it to warm up to the set temperature.
• Step 2. Once the oven is warm, place the oven in manual mode and create a 1 minute recipe with a single event, 10% air and 30% microwave.
• Step 3. Place a water load into the cook cavity. The water load must meet the following specifications:
  • Volume: 275 ml ± 15 ml
  • Temperature: 68℉ ± 9℉
  • Vessel: Pyrex dish capable of 500℉
• Step 4. Close the oven door and press the Cook key.
• Step 5. Measure the microwave emission around the door slowly, moving the meter sensor at 0.5 inches per second.
• Step 6. As the microwave leakage is observed while moving the sensor, not any meter spike areas that come close to 5mW/cm2 for later re-measurement.
• Step 7. Replace the water load every 60 seconds until the test is completed, and also after scanning the door.
• Step 8. Close the oven door and return the meter probe to any “meter spike” areas and allow the probe to remain in the area for 17 seconds. Note the highest reading obtained.
• Step 9. Once the test is complete, open the oven door and dispose of the hot water. Let the steam dissipate with the door open.

When to Perform an RF Leakage Test

This type of test will need to be completed at the end of the following service tasks:

• The door is removed, replaced or adjusted
• The waveguide is removed or replaced
• The magnetron is removed or replaced
• The door switch is adjusted or replaced
