[Amps] Alpha Ip problem (score: 1): Author: "Robert Kirkland" <alpha76@triton.net>; Date: Mon, 4 Aug 2008 22:16:26 -0400; The Alpha 76 indicates plate current by converting an 0-1 ma. old 1000 ohm iron vane meter to a volt meter and measuring the voltage drop through a series resistor. The volt meter circuit has an adju; /archives//html/Amps/2008-08/msg00021.html (6,709 bytes)
