ДНЕСГ 500-1, разогрев катода
Скорее всего излишне сильный, надо немного слабее греть, чтобы зря не портить оксидное покыртие. Хотя по правде говоря мне точно не известна максимально допустимая температура его прогрева.
Несколько раз видел и фальстарты при размыкании цепи прогрева раньше достаточного разогрева спиралей. При этом лампа дает яркую кратковременную вспышку оранжевого цвета по всей длине колбы, только у электрода при этом вспышка сиреневого цвета наблюдается.
