4. Power Meter Function
The power meter function is provided to
monitor the condition of the transmitter by
measuring the relative power being genera-
ted in the transmitter. This meter will mea-
sure up to 10 or 100 Watt RF power, depen-
dent of the position of the sliding switch (4)
[10W/100W].
5. Power Measurement
Do not turn on the transmitter, while the antenna and test
meter are disconnected.
> Connect the meter with the transmitter and the antenna in the
the same way as for the SWR measurement.
> For measuring of standard CB transmitter with 4 Watt RF power
power, place the sliding switch (4) [10W/100W] to the 10W position.
> Turn the transmitter on and read the power from the upper scale
(WATT) of the left display (5).
Unusual, high measurements, above the rated power of the trans-
mitter could indicate a faulty antenna system. Check all connec-
tors for unsatisfactory connection.
6. Field Strength Measurement
The SWR-1180-P can detect radiated energy with its whip radio
antenna (8). The sensitivity of the filed strength meter (4) can be
adjusted by the CAL-control (3). For the field strength measure-
ment the meter must be disconnected from the antenna feed line
and placed close to the radio-antenna.
Do not touch the small antenna of the meter with the radio
antenna during the measurement.
> Position the SWR-1180-P within a range of 1 meter of the radio
antenna.
> Turn on the transmitter, press the PTT key and adjust with the
CAL-control the pointer of the right meter to a center postion. It
may be necessary to re-position the meter to obtain an indication.
> After every adjustment of the antenna repeat the procedure.
