TKM7K Track Voltage Tester for HM7000

About the Product

The BLOCKsignalling TKM7K Track Voltage Tester is an advanced diagnostic tool designed to quickly identify voltage drops, poor rail connections, and power issues that can affect the smooth running of model locomotives. It provides an instant visual indication of track voltage, making model railway fault finding fast, simple, and effective.

To use the tester, simply place the unit onto the track. The built in LED indicators will immediately display the voltage present, allowing you to quickly identify weak connections, inconsistent track power, polarity issues, and overvoltage conditions on both DC and DCC layouts.

Optimised for Hornby HM7000 systems, the TKM7K is also suitable for a wide range of model railway layouts and control systems.

Voltage Indication

• Six LED indicators provide a clear visual guide to track voltage levels.
  
• Yellow LEDs indicate 6V, 9V, and 12V, highlighting insufficient voltage for reliable locomotive 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.

Compatibility Information

• Instant LED indication of track voltage.
  
• Helps locate voltage drops and poor track connections.
  
• Detects DCC signals and reversed track polarity.
