Nije vezano za mjerenje maksimalne dopušte struje ali je zanimljivost. Ima tome mjesec dana ili tako nešto sam spojio jednu crvenu LED(neka NOS od 5mm) na nekakav "curve tracer" iliti octopus tester te povećavao napon tj. struju kroz nju imao sam nekoliko otpornika za ograničenje struje te sam se bome "namučio" dok ju nisam skurio. Izdržala je čak 200mA prije nego je rekla zbogom.
Ako imaš skop(sa XY modom) da se za pola sata složiti takva skalamerija pa onda možeš lijepo vidjeti na njemu ča se točno dešava sa LEDicom kada povećavaš struju kroz nju.
