Minivoltmetru digital 4.2V ? 32V, curent continuu

Minivoltmetru digital 4.2V – 32V, curent continuu

Minivoltmetru digital, de precizie, pentru curent continuu, masoara voltajul in gama 4.2V – 32V. Precizia sub 10V este de 0.01V, peste 10V, precizia este de 0.1V. La tensiuni mai mici de 4.2V, display-ul nu mai este foarte luminos dar nu exista pericol de ardere si nu este afectata precizia masuratorilor. La tensiuni peste 32V, se poate arde.

Display pe led, culoare rosie, conexiune cu 2 fire cu protectie la polaritate inversa. Nu necesita sursa de alimentare suplimentara.
