 Warnings and Precautions
• Inspect the RF detector before every use. Do not use a damaged unit.
• Do not operate the instrument in an explosive atmosphere.
• To reduce the risk of fire or electric shock, do not expose this product to
rain or moisture.
• To avoid false readings, which could lead to possible personal injury,
replace the batteries as soon as the low battery indicator (LoBat) appears.

INTRoDUCTIoN

The TX900 is a microwave radiation detector for checking RF power leakage
in microwave cooking ovens. The TX900 has temperature compensation and
Auto-zero for the display.

oPERATIoN

 WARNING
2
1 mW/cm Threshold: If a signal level greater than 1 mW/cm
beeper will sound and remain on until the signal level falls below 1 mW/cm
overload: If a signal level greater than 10 mW/cm
testing, an "overload" condition will be indicated by the display showing
the letters "oL".
Linear display: In the event that the signal is a high, rapidly varying value, it
may be useful to refer to the 10 point linear display to give an indication of
the average rather than the rapidly changing alpha numeric display.

Rf Power Leakage testing

1. Fill a beaker with 275 cc ±15cc of water and place it in the microwave
oven to act as a load for the magnetron.
2. Point the instrument away from the potential RF source and depress the
TEST button. This turns ON the instrument and sets 'Auto Zero' the LCD
display for '0.0' mW/cm
3. Setup the microwave oven for full power and switch ON.
4. The TEST button must be held down during testing.
5. Move the tip of the instrument cone (almost touching) at about 5 cm /
second around possible leakage areas - door seals, hinges, door seams,
windows, welds and rivets.
6. Leakage should not exceed 5 mW/cm
Many manufacturers have lower emission levels from their ovens. Consult
the microwave oven manufacturers data for specifications.
7. Write down the highest reading displayed during the test and location on
a suitable label, which should then be affixed to the oven.
