Features:

• A bright flashing LED and loud pulsating beeper indicate local continuity
• Remote continuity — with the use of the remote probe, it does not tie-up two people when identifying and labeling long distance wire/cable runs
• Flashing remote probe - Two lead, bi-color (red/green) LED probe allows a single user to identify up to three wires or cables at a time for correct labeling with only one trip to the other end location - cuts down on multiple trips back and forth
• Polarity verification - Drives a 20mA DC current pulse through the wires or cables under test to the bi-color remote probe; This enables the technician to identify each of the wires under test at the other end of the cable run and eliminates the possibility of false high impedance readings
• Lightweight/Pocketsize - clips on and hangs from the cable(s) under test without falling off
