You can read swr directly on the swr meter. It's the glare from the light. Power for CB you'll just leave the 3 position switch set to 10 and read watts output from the transceiver dividing meter reading by 10 to obtain 10 reading.

I only used the meter a handful of times last time being last summer. It is calibrated from 1 to 3, with a red line above I no longer have a CB radio and antenna that requires tuning. Measurements when connections are made as noted above, you are ready to use your tester.

Swr to measure standing wave ratios, set cal swr switch to cal position. 3 oz 830g power function there are three ranges of power from to 10 watts for CB and for ham and business type transceivers.

It's actually a very good quality meter that proved helpful to me. Be sure all connectors are secure.

For maximum efficiency, the swr must be as low as possible this means that all of the power from the transmitter is being radiated from the antenna. Return the cal swr switch to swr position and read your swr on the meter. As this is an electronic item I am selling it as is. If your reading is more than 3, you should correct the mismatch between the transmitter and antenna system.
