In many cases, one grows fond ot certain test gear of which all the shortcomings and inaccuracies are thoroughly Iamiliar. In not a fewcases, the good old continuity tester or the battered multimeter remains in use for years for no other reason than that it is there and easy to use. The instrument described as this month's intermediate-Ievel project has so many uses that it may weil become one of your favourites on the test equipment shelf.
