The Continuity Tester Pro is a professional instrument for wire and cable testing. It uses a 20mA DC current pulse to drive two probes and measure the continuity of wires or cables. It can identify up to three wires or cables at a time and display red or green LED indicators at the other end to indicate the connection status.
The EXTECH CT20 is a Continuity Tester Pro designed for one-person operation on wire and cable testing. It features a bright flashing LED and loud pulsating beeper to indicate local continuity.
For remote identification, the device uses a two-lead bi-color (red/green) LED probe. This allows a single user to identify up to three wires or cables at a time for correct labeling without multiple trips. The system drives a 20mA DC current pulse through the wires to verify polarity and eliminate false high impedance readings.
