The power sensor can indicate the voltage polarity, check switches, relays, the on-off activation of diodes, fuses, and circuits. It allows for monitoring and detecting short circuits.

It features a long cable, which facilitates testing any electrical system. It is extremely sensitive and has short-circuit protection, as it can immediately check for poor ground contacts.

The sensor is easy to use without complicated procedures, convenient and practical. It can test the polarity of electrical wires and plugs, and is suitable for truck and car manufacturing.
