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.

Configuration

To make this as simple as possible for you, the Profi- Tester comes with useful features: 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 on – 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.
