Connect the Bird Digital Power meter as follows:
Connect the 9 pin male end of the D sub cable to the “Sensor” input on the Bird
Digital Power Meter Model 5000EX. Connect the 9 pin female end of the D sub
cable to the Bird Model 5010 Directional Power Sensor Module. Insure that the
DPM-0.5E is installed in the “Reflected” socket of the Bird Model 5010 with the
arrow pointing towards the other socket. Insure that the DPM-5E is installed in
the “Forward” socket of the Bird Model 5010 with the arrow pointing towards the
other socket.

Verify that the display is showing from the top “ W 5 W”
If display does not show as described in 4a do the following:
Press orange arrow under “FWD Units” until display reads W
Press “5” on numeric keypad.
Press enter key
Press “esc” key.
Press orange arrow key under “FWD Units” until display reads “MW”.
Press orange arrow key under “RF Units” until display reads “VSWR”.

Tower Voltages Test:
1)
Using the voltmeter, measure the following voltages and record the
measurements:
a)
AC Supply Voltage: Measure the AC Source Voltage on the AC Voltage
connection terminals. The voltage should be b112vac and
+125vac. If the voltage is within range, record the voltage on the
Commissioning / Annual Record Data Sheet and go to the next Test step. If
the voltage is out of range, contact the facility representative and notify
them of out of range AC power at the tower.
b)
Visibility Sensor Power Supply voltage. Measure the Visibility Sensors
Power Supply voltage on the Vis PS connection terminals. The voltage
should be b12 and +12.5vdc. If the voltage is within range, record
the voltage on the Commissioning / Annual Record Data Sheet and go to the
next Test step. If the voltage is out of range, use a screwdriver to adjust the
voltage on the power supply adjustment mechanism. If the voltage will not
adjust to within range, replace the power supply.
c)
DCP/Obstruction Light Power Supply voltage. Measure the DCP/OBS
Power Supply voltage on the DCP PS connection terminals. The voltage
