Using the meter
Having focused on the subject set the Lens Aperture Ring
[9] in the middle of the range (say f/8) and press the
Shutter Release Button [3] about half-way. This will switch
on the meter and one of two red lights on the right-hand
side of the viewing frame will
come on. If it is the upper one this indicates over-exposure
and the Aperture Ring [9] should be turned clockwise thus
reducing the amount of light reaching the film. Should the
lower light come on it indicates under-exposure and the
Aperture Ring [91 should be turned anti-clockwise. Turn
until both lights flash rapidly in sequence - this is the
correct exposure.
If it is not possible to get both lights flashing in sequence
even at the end of the range of the Aperture Rinai9l then
alter the Shutter Speed Dial [1] up or down and repeat the
process. The meter fitted in the Zenith 12 XP is very
sensitive and in some cases the indicator lights may move
from top to bottom without an intermediate 'flashing' stage.
In this case choose the exposure at the point of the change
from top to bottom when the latitude of modern film will
still give you the correct exposure
