TKM7K Track Voltage Tester for HM7000

About the Product

The BLOCKsignalling TKM7K Track Voltage Tester is designed to quickly identify voltage drops and poor track connections that can affect the smooth running of model locomotives. It provides an instant visual indication of track voltage, making fault-finding fast and straightforward.

Simply place the unit on the track and the built-in LEDs will illuminate to show the voltage present, whether the layout is powered by DC or DCC. The tester is optimised for Hornby HM7000 systems, but is suitable for use on a wide range of layouts.

Voltage Indication

• Six LED indicators provide a clear visual guide to track voltage levels.
  
• Yellow LEDs indicate 6V, 9V, and 12V, showing insufficient voltage for reliable operation.
  
• Green LEDs indicate voltages between 15V and 18V, representing the ideal operating range.
  
• A red LED indicates voltages above 21V, providing an overvoltage warning.

An additional red LED illuminates when track polarity is reversed or when DCC is detected, helping to quickly identify accidental polarity reversal or confirm DCC operation.

Compatibility Information

• Optimized for use with Hornby HM7000 systems.
  
• Suitable for both DC and DCC-powered layouts.
  
• Contact spacing on the base is suitable for Z, N, TT, HO, and OO gauges.

Application & Use

Ideal for checking track voltage consistency, locating poor connections, and diagnosing voltage drop issues anywhere on the layout.
