Setting the Full Scale Power
For element-based sensors, enter the power rating
listed on the forward element before making any mea-
surements. Also, check that the reflected element’s
rating is 10% of the forward element’s.
The Bird Site Analyzer will automatically set the full
scale power for sensors that do not use elements, such
as the Bird 5011 or 5012.
Zeroing Bird Power Sensors
Over time, the sensor’s “zero value” (reading with no
applied RF power) can drift, making all readings inac-
curate by this value. For example, if the zero value is –
2 µW, measuring a 5 mW signal will give a reading of

CAUTION
When using a Bird 5011 or 5011-EF, do not exceed 2
W average or 125 W peak power for 5 µs. Doing so
will render the sensor inoperative.
