How to check if the meter is reasonably accurate :

– Make sure that the pointer is reading zero with the cell covered with your hand. If not, adjust with the screw on the base.

– Point the meter to a clear north sky at any time between 10 A.M and 2 P.M.(Northern hemisphere) Southern sky (southern hemisphere) There must not be any clouds or haze.

– This should translate to f/16 at 1/100 or LV 15, with film speed set to ASA/ISO 100.
