The Complete Guide To Extech Tg20: Specifications, Pros And Cons, Troubleshooting, And Buying Tips

Extech TG20 Information

The Extech TG20 Wire Tracer Kit is a versatile tool that can be used to trace wires, identify wire pairs, check continuity, and test telephone line polarity. It is a valuable tool for electricians, technicians, and anyone who needs to work with wires and cables.

Introduction

The TG20 Wire Tracer Kit consists of a transmitter and a probe. The transmitter has two output cables that are terminated in a modular RJ11 phone connector. The probe has an amplifier that allows you to hear a tone when it is placed near the selected wire or cable.

The TG20 has two modes of operation: tone and continuity. In tone mode, the transmitter emits a tone that can be heard through the probe. This allows you to trace a wire or cable by following the sound of the tone. In continuity mode, the transmitter sends a signal to the probe and the probe indicates whether the wire or cable is connected.

The TG20 also has a polarity test function that can be used to check the polarity of a telephone line. This is useful for troubleshooting problems with telephone lines.
