20200506_213022.jpg 20200506_212917.jpg This is a cool little meter. The power, both avg and pep are relatively accurate when compared to other meters. The SWR measurement is way off. With a working meter showing a 3.0 SWR, this meter shows 1.7. I'm assuming it's simply out of calibration. See photos. There are four pots in the meter. Is one of them for SWR calibration? Thanks.
 

There are four pots two adjust forward power and two adjust reflected power for the different power scales. It's really easy to tell which one does what by using a known standard and a dummy load, and simply turning each one.

But it pays to have a known accurate standard and a very good dummy load, or any adjustments may be for naught
 
What did you pay for the Metre out of I interest in currently looking to purchase a swr/ power metre I can use in Line in my car
Paid $119.00 for it new. I sent it back, and got a refund. Picked up a Diawa CN-501H for the same price. The Diawa works like a charm.
