You just move the plugs and get 1Ω to 99Ω. Of course it is useful just for AC (low frequency - I use it to test transformers) as electronic loads offer much better performance for DC. --- End quote --- Thanx What experiments You do with transformers? |

nice boxes. There is an aluminum profile by Makersled.com looking exactly like for this purpose. |

I remember my old Boss making the point years ago, that it is a "Test" Load not a "Dummy" Load, because it provides a real load for the DUT. A "Dummy"Load would be a fancy looking empty box! Transmitter manufacturers usually eschew the "Dummy" term, calling the load you test with, either a "Test Load" or an "Artificial Load". |

Found a place by me that is gonna laser engrave my faceplate for me. Figgered might as well make it pretty. Found a free version of CAD software so I could make a template with everything laid out already to lower the cost. Quite the learning curve to that software. |O |
