Stupid questions about a Gossen Luna-Pro F Digital meter

Hello,

I just bought a used Gossen Luna-Pro F Digital meter and I have a couple of
stupid questions for you experts out there...

1) Is there any sort of battery check on this meter? I don't see one when
scrolling through the functions nor is there one on the display.

2) On the right-hand side of the display, there are a couple of little letters
that appear depending upon the exposure selected, or so it seems. One is an "s"
and the other is an "m," and they appear alternately. For example, if I select
a really long shutter speed (i.e., several seconds) the "m" appears. Otherwise
the "s" is displayed. What do these mean?

I've pretty much figured the rest of the stuff on this little guy out, but
these two things have me stymied.

Thanks. I appreciate any help you can give.
Scott

I believe the display should be:
blank: fractions of seconds
s: second(s)
m: minute (s)

 

Thanks, but this site is for an analog Luna Pro F. The one I'm trying to learn
about is a Luna Pro F Digital.

Thanks anyway,
Scott

I believe the display should be:

Thank you very much, Alan. I appreciate it.

Thanks. It appears to be working fine, so I suppose the battery's good.

Thanks again,

I always find it hard to remember which Gossen meteris called what in the
U.S., but i believe the Luna Pro-F Digital to be the Sixtomat Flash, right?
There will appear a battery warning signal (the word "BAT" in a box) in the
display of this meter when the battery is running low. The "active" test you
can do is see if this signal appears whenusing the thing. No button to press
except the ones for normal operation.

As long as other things appear too on the display, there is still some power
left in the battery, but not much. When "BAT" is the only thing on the
display there is no power left.

 

....except enough to display BAT?
