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.

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!

The problem is the CAL mark is 1" wide , sorta like this, on the right
side
of the meter.

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.

My guess is all the way to the CAL mark... I seem to remember having one
of
those.
