3. While pressing the orange button on the MD-2000 unit, start the operation of the microwave oven
(highest power output setting). The microwave oven must be operational for a minimum of 30
seconds.
4. Place the MD-2000 unit within 2 inches around the door cracks of the microwave oven. The meter
MUST be held in a horizontal orientation perpendicular to the surface you are measuring, such that
you can read the display from the top. Do NOT turn the device vertically as this will severely affect
the unit’s accuracy (see drawing below for proper orientation).
Microwave oven and MD-2000 in side view. Note the orientation of the MD-2000
and the oven door. During the test the oven is plugged in and running.
5. Note the MD-2000 readings on the display. Typical readings of properly insulated ovens will show
a value of less than 1.00 mW/cm
2
. Readings of 5.0 mW/cm
2
or greater will be accompanied by a
beeping alarm tone and the flashing of the red warning lamp. Microwave ovens that emit 5.0
mW/cm
2
or greater of energy violate the FDA and EPA recommended safety levels and must be
replaced or repaired immediately.
6. Readings close to but less than 5.0 mW/cm
2
may affect wireless communications and should be
located as far as possible from any wireless devices. As mentioned earlier, Spacelabs Medical
recommends that ovens in proximity of wireless networks emit less than 1.5 mW/cm
