I doubt it will injure it. Selenium cells become non-linear when
they are old. Most exposure meters have an overlap between high and low
ranges. The test is to measure light that falls in the overlap range on
both ranges. The reading should be the same. When a selenium cell ages
it becomes less sensitive to _high_ light levels so it will give a low
indication at the top of the low range as compared to the lower part of
the high range. If its close to being the same on both ranges its OK.
FWIW, I don't think the FTn has a selenium cell in it.

My 2.8F Rolleiflex has it’s original selenium meter from about 1970 or so. It
has always checked out perfectly in agreement with my newer digital meter.
Today I took it outside in the blinding sun just to compare the meters again to
see if they still agree on the light bouncing off my white garage door and they
do. However as I walked in the sun I had the camera cradled in the crook of
my arm without thinking about it and after awhile I noticed that I was aiming
the meter directly at the Sun !! Now I know I ruined my old Nikon FTn meter
by accidentally aiming it at the sun, the needle went all the way over and
never came back. So I am wondering if it is possible to ruin the Selenium
meter on my 2.8F that way. After I did it today I re checked and it seemed
just fine.
thanks
