ZERO ADJUSTMENT
Check the meter periodically to see that the painter exactly opposes the zero mark when all light is excluded
from the window of the main cell and the flip-up booster is retracted within the body of the meter. Should it be
'off zero, turn with a small screw driver, left or right, the screw located at, the back of the meter near the catch
for the flip-up booster. A small turn is sufficient to center the pointer correctly at zero.
1. Do not subject the meter to rapid changes of temperature or humidity Never place the meter on a magnetized
material. In case this condition lasts, it is quite possible that the meter becomes inoperative.
2. Be careful not to drop it or jar it suddenly as this will cause a displacement of the bearings of the
microammeter or more serious dam age.
3. When not in use, keep it stared in its carrying case in a cool, dust free place.
CONSISTENT OVER OR UNDEREXPOSURE
This sometimes happens. In this case make the necessary compensation by seating the ASA or DIN value
slightly over or below (as the case may be) the valve given by the film manufacturer Do not be afraid to
experiment. This is the stamp of a serious photographer.
