Chapter 3 Operation
The Bird Digital Power Meter is very easy to operate.
Once a sensor is connected, turn the DPM on and take
a reading. Additional commands are available,
depending on the sensor used.
Normal Operation
y Connect the sensor.
y Turn on the DPM.
y Set the measurement units by pressing FWD Units
and RFL Units.
y If you know the system loss or are using an
attenuator, add the losses (in dB) of all components
in the system. For attenuators and other frequency-
dependent components, use the loss at the measured
frequency. Then, press OFFSET and enter the total
loss in dB. This will allow you to read the actual line
power. The DPM accepts offsets from 0 to 100 dB.
y Turn on the RF source.
y Read the power level on the display.
 NOTE: The analog bar graph will respond immedi-
ately to changes in the RF power. The major and
minor displays will respond after a delay of 1 to 13
seconds, depending on the power level.
