The Noyafa NF-8509 digital multimeter with buzzer measures AC/DC voltage and resistance, and checks the continuity of cables and conductors. Its built-in NCV detector identifies high- and low-level voltages without contact. The device also tests network cables, cable length, line sequence and PoE power.
Continuity mode activates the buzzer when resistance is below 50 Ω and checks diode polarity and forward voltage drop. The device features a backlit display, LED lighting and an anti-interference function. Automatic power-off and an ambient temperature reading round out its features.
