<p>The exposimeter consists of a current-pulse frequency converter for generating a pulse frequency corresponding the current magnitude, a pulse counteR, and recording and/or evaluation means for each counter result. The pulse counter consists of a combination of dual and decadic step-down stages controlled by logic switching elements so that only pulses generated by the converter reach the recording and/or evaluating stage, that in their sum correspond to film darkening values with identical distances in their percentage. Pref. the darkening values distances are 20%.</p> |
