May be you know the situation: In front of you there is a digital decoder on the workbench, and before you undertake its complicated installation into the loco, you would like to know if the decoder works as advertised. But, how do you test it? The Profi-Tester helps you: It's designed for testing decoders before these are installed into a loco. The Profi-Tester is simply hooked up to your digital central station, or the LokProgrammer.
To connect the decoder, there is a 6-wire NEM 651 harness and an 8-wire NEM 652 interface, as well as a 21-pin mtc-interface available. Plug it in - bingo! Locos without an interface board can be hooked up with alligator clips. A high quality, 5 pole skewed armature can motor with flywheel serves to check the motor output: It's this simple to test the slow-, and constant speed characteristics of your decoder. A LED-monitor informs you about the function of the head-, and rear light output, as well as function outputs AUX 1 (green), and AUX 2 (violet). A 20 mm loud speaker is included for testing LokSound-Decoders. A screw terminal assures safe connection between your Profi-Tester and the digital central station-, or LokProgrammer. Due to its sensible features and simple handling, the Profi-Tester will soon become an indispensable helper in your shop. helper in your shop.

I have only recently purchased my tester and have not yet used it but it certainly looks robust and definitely has all the features I will need. A big thanks to Model Train Stuff for good value and great service.

Basically a locomotive without wheels September 29, 2011
Reviewer: JerseyHiker from Bear, DE United States  
I bought this unit to re-program several very old MRC decoders used only with MRC’s Command 2K unit.  With the ESU unit I was able to test new & old decoders using both the MRC and Digitrax Zephyr Xtra and was able to change the old MRC decoders to 24/128 steps to work with the Digitrax Zephyr.

The unit has lights (LEDs), motor, and a speaker, with several types of decoder connectors.  I only tested the 8-pin socket and bare wire connections and they worked exactly as predicted, with motor and lights working perfectly.  I did not test the sound features because I had no sound decoders available for testing - I have no doubt they will work well also.  

One of the spring-loaded push-in wire connections does not “bounce back” anymore, but I think I may have accidentally pushed it too hard - the electrical connection in it is still fine.  

Overall it’s a fine product that does exactly what it is supposed to do, but it is mechanically delicate – don’t use it as a Frisbee  :-)
