From time to time, test equipment needs maintenance too, especially the less expensive equipment. Sorry I didn't do a full show on this. After recording I realized I didn't show the vent holes on the potentiometer where I squirted some contact cleaner. But, same goes for knob switches as well as standard contact switches on spaying cleaner into them.
I also showed re-checking / confirming sign wave reflection from my antenna. I did this to confirm calibration on my meter is as it was when I first got the meter to tune my antenna.
I hope this help you to see operation of these little SWR meters if you have not used one before.
