Selelekela

E sebelisetsoa ho tseba hore na Planck e lula e sebelisetsoa ho bonts'a phello ea motlakase joang, Filter e sebelisa seholisa se sebetsang se phahameng se kopaneng le moralo o khethehileng oa potoloho, "tube" ea "photoelectric" e sebetsang hantle, mme ho daela ke sebopeho sa sefahleho se nang le moralo oa lipale le mesebetsi e felletseng.

Photocell nahanela A 1mA / LM, lefifi hona joale ≤ 10A; zero drift ≤ 0.2% (palo e felletseng ea ho bala, 10a gear, kamora metsotso e 20 ea ho futhumatsa pele, e lekantsoe nakong ea metsotso e 30 tlasa tikoloho e tloaelehileng) Pontšo ea LED ea 3.5-bit, ponahalo e tlase ea hajoale ke 10a, pontsho e nyane ea motlakase ke 1mV, ka hona "mokhoa oa hajoale" kapa "mokhoa oa matšeliso" o ka sebelisoa ho lekanya motlakase o khaotsoeng ka nepo
