As you have the meter in your hands looking at it ,on the right you will see the letters ANT. for antenna .this is where you attach your antenna wire . Now you need a jumper wire to attach to the side that says TRANS . Attach one end of the jumper to the meter and the other end to the radio .make sure the meter is on SWR set the meter to forw and key the mic. now use the knob to adjust for set. Now set meter on ref and key the mic. the number you see is your SWR This should be done on channels 1, 40 and then on 20.for a mid band SWR.

Watch the meter as you adjust the antenna. Try to get an SWR of 1:1, or as close to it as you can get.

go to Rad Shack and buy a small three way switch and put it in yourself.Is it stuck on the high end or the low? If its the high end you can still get a low reading from it. To have someone fix it may just cost as much as a new meter.So,you might think about getting a new one because you won't find another like it on the market.You can get a dosy 4002 or an astatic 600 but I'm 100% sure there are no 700's .I think workman has a twin to it but thats all I can tell you .

take your multimeter and go find it.connect one lead to the wire and the other serch for the point at which it connects to the board.
