The MS6812 cable tracker manual mainly functions to judge whether the cable line is continuous, track the cable line, receive the audio signal in the cable line, judge the status of the working telephone line, and send a single audio or dual audio signal to the target cable line.
The Cable Tracker MS6812 is a handheld tool for installing, testing, and maintaining various electrical and telephone cables without damaging insulation. It includes a sender (Sender M96812‑T) and a receiver (Receiver M96812‑R) that work together to locate cables, verify continuity, and identify telephone line states such as idle, ringing, or off‑hook.
The manual explains how to use the CONT function to test cable continuity, the TONE function to send audio signals, and how to interpret indicator lights. It also covers battery replacement for both the sender and receiver, safety warnings, and proper handling to avoid water exposure or high‑voltage environments. This manual is written in Chinese.
| Maximum cable resistance for continuity test | 10 kΩ |
|---|---|
| Maximum allowable AC signal during testing | 24 V |
| Battery type | 9 V |
Set the sender to CONT mode, connect its red and black leads to the two ends of the cable, and if the CONT indicator lights green, the cable is continuous (resistance ≤ 10 kΩ).
Open the battery cover on the sender or receiver, replace the old cell with a new 9 V battery, and close the cover.
Do not expose the equipment to water, and do not use it in high‑voltage environments or apply AC signals greater than 24 V during testing.
