I've used the same procedure. When the light meter in the K-1000 shut off
for lack of light, I punted and used spot meter mode of my PZ-1p body as a
light meter since it is more sensitive. Without it, I would have had to
guess -- I probably would have picked the part of the scene I wanted to
meter from and then moved close enough to get a reading off only it to use
as a starting place.
One thing I learned to be careful about with my K-1000 (and maybe others
need to be as well?) is that down at the extreme end of the light meter
range, the metering gets severely non-linear. When I'm close to that range,
I always check the reading by making a one-stop change. If the needle
deflects more than I expect a one-stop change to do, then I can't trust
either reading.
hope that helps,
