I have made resistance checks at U12 with another multimeter (cheaper one, the first one was a FLUKE 175 ) and I get more than 2 kohms, forward and reverse polarity. I have made some investigation: The fluke uses 7 V to make resistance measuremens, and the cheaper one uses 0.6 V, so that could explain the diference. What do you think?, Do you think that I sould worry about the resistance checks or continue doing the Initial Power On Check? Thanks Ramiro. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
