Instructions for use
Connect a coaxial cable (about 50 cm long and with a PL259 connector at both ends) to the
connector for the antenna on the radio and to the TX connector on the SWR/Power meter.
Connect the antenna cable to the ANT connector on the SWR/Power meter.
SWR measurement
•
Move the PWR/SWR switch to the SWR position.
•
Move the FWD/REF switch to the FWD position.
•
Hold down the PTT button on the radio microphone while rotating the CAL knob on the
SWR/Power meter until the needle reaches the SET mark.
•
Move the FWD/REF switch to the REF position. Now the reflected power will be
indicated on the SWR/Power meter screen.
•
Leave the switch in the REF position and tune the antenna until you get the lowest value
of the reflected wave.
Note: If the SWR is higher than 2.0:1, either you need to re-tune the antenna or there is a
problem with the cable or the antenna.
Power measurement
•
Move the PWR/SWR switch to the PWR position.
•
Move the FWD/REF switch to the 10W or 100W position depending on the output
power of the transceiver (0-10W or 10-100W).
•
Turn on the transceiver and press the PTT button on the microphone.
•
Now you can read the power on the Watt scale of the SWR/Power meter.
•
To get an accurate reading, the SWR should not be higher than 1.5:1.
Warnings
•
Do not turn on the radio before connecting the antenna and the SWR/Power meter.
•
Do not disconnect the cable of the antenna while transmitting. The high voltage may
damage the transceiver.
•
Please do not subject the meter to violent shocks, as this can damage the integrated
sensitive meter.
