Mastech MS6812A Wire & Cable Tester

Description

The Mastech MS6812A is a professional, two-part cable tracker kit primarily designed for tracing and testing low-voltage wires like those used for telephone and network lines. It consists of a sender (tone generator) and a receiver (probe), which use a tone signal and an audible/visual indicator to locate a specific wire within a bundle without damaging its insulation.

Key Features

• Tone generator: The sender unit can send either a single solid tone (1500Hz) or an alternating dual-tone (1300–1500Hz).
• Probe receiver: The receiver is a handheld probe that detects the tone signal emitted by the sender. Its adjustable sensitivity helps pinpoint the exact cable or break point.
• Audible and visual indicators: Both the receiver and sender provide feedback through sound and LED indicators.
• Telephone line testing: The device can identify the state of a working telephone line, indicating if it is idle, ringing, or busy.
• Continuity testing: It can judge the continuity of cables and wires to check for breaks or short circuits.
• Power: The unit is battery-powered, using two 9V (6F22) batteries.
• Certifications: The product is RoHS, CE, and ETL compliant.
