SWR Meter
Micronta 21-525B. Reading the instructions from the web and it says "Push
transmit button and rotate the calibration control until the meters needle aligns with the Cal mark" The problem is the CAL mark is 1" wide , sorta like this, on the right side of the meter. |_______| cal Do you adjust to the beginning of the area, middle or far right where the CAL is printed? The entire CAL area is in red. Thanks! -- Jim Douglas http:\\www.genesis-software.com Latitude 32.5818 Longitude -96.5412 Elevation 497 |

My MFJ VHF SWR meter is pretty much the same, all the way to the right by the CAL mark. dxAce |

Thanks for the quick response. I was afraid of that answer and the rest of
the calibration is way off if I set it to the far right! Back to work I go! Thanks again! "dxAce" wrote in message ... Jim Douglas wrote: Micronta 21-525B.

The tic mark next to SET or CAL is the alignment point. The red band
indicates an excessively high SWR when in measurement mode (after calibration). I have a Micronta 21-520A and would not consider it to be very accurate.
