Kroz potove tece konstantna struja oko 450uA koja se dobija iz strujnog izvora koji cine Vref/(R18+R19).
Kroz R17 ne tece struja. Jedna od modifikacija koja bi verovatno unela neko poboljsanje je da se bas ovaj strujni izvor zameni sa nekim CCS-om npr sa TL431 i jednim PNP tranzistorom.

Slican koncept koriscen je i kod jednog lab psu-a takodje iz ELV-a koji sam odavno napravio i dan-danas ga koristim u radionici.
