1. [Amps] meter shunt (score: 1): Author: "carl seyersdahl" <carlseye@tampabay.rr.com>; Date: Sat, 20 Sep 2003 13:26:37 -0400; I am repairing an FL2100B in which the powersupply went south, and I have found what appears to be the meter shunt burned out. (IP) It is a wirewound unit , and the manual doesn't tell me what it's v; /archives//html/Amps/2003-09/msg00174.html (6,831 bytes)

Re: [Amps] meter shunt (score: 1): Author: "Dr. David Kirkby" <drkirkby@ntlworld.com>; Date: Sun, 21 Sep 2003 05:59:04 +0100; If the resistor has burt out, there is a good chance the mater has too, so I would check that first. The value depends very much on the meter you have - its FSD and internal resistance as well as the; /archives//html/Amps/2003-09/msg00179.html (9,378 bytes)
3. [Amps] Meter shunt (score: 1): Author: "Robert Perdue" <kc0hfl@cox.net>; Date: Fri, 29 May 2009 10:50:35 -0500; I have a Weston 301 meter 0-100 ma scaled meter and wish to make a shunt to use for screen current in my 4-1000 amp. The screen voltage is 300V I have used the formula RS=RM/(IS/IM) Okay here is what; /archives//html/Amps/2009-05/msg00255.html (6,473 bytes)

It probably already contains the correct shunt to make it 100mA full scale. Have you measured it to see what it actually reads? WB2W; /archives//html/Amps/2009-05/msg00256.html (6,939 bytes)

Re: [Amps] Meter shunt (score: 1): Author: Ron Youvan <ka4inm@tampabay.rr.com>; Date: Fri, 29 May 2009 13:03:12 -0400; Usually, but not always, meter cards (scale) will indicate the meter movement sensitivity in the lowest right hand location on the card, normally in a hard to see location. Like a 10 mA scale might; /archives//html/Amps/2009-05/msg00257.html (7,819 bytes)
6. Re: [Amps] Meter shunt (score: 1): Author: "Steve Katz" <stevek@jmr.com>; Date: Fri, 29 May 2009 10:09:45 -0700; Surely, this depends on the meter. It's easy enough to measure and find out. Most of my "1mA" to "100mA" meters here (Simpsons, Westons) have those shunts built in. "1A" and higher meters almost alwa; /archives//html/Amps/2009-05/msg00258.html (8,049 bytes)
7. Re: [Amps] Meter shunt (score: 1): Author: "Carl" <km1h@jeremy.mv.com>; Date: Fri, 29 May 2009 20:40:48 -0300; Unless you take measurements the meter resistance is an unknown. The Handbooks and internet both describe the process. After that the math works. Carl KM1H ___________________________________________; /archives//html/Amps/2009-05/msg00264.html (8,295 bytes)

Re: [Amps] Meter shunt (score: 1): Author: Roger <sub1@rogerhalstead.com>; Date: Fri, 29 May 2009 21:13:50 -0400; It's almost a necessity as many meters have internal shunts and that's when you end up with those super low calculated external shunt values. At work we had a number of feed back sensors in SCR contr; /archives//html/Amps/2009-05/msg00268.html (9,368 bytes)

10. Re: [Amps] meter shunt (score: 1): Author: TexasRF@aol.com; Date: Thu, 25 Aug 2011 07:25:06 -0400 (EDT); Hi Carey, there are number of ways to design meter shunts. A method used by many is to install a low value resistor in series with the circuit and measuring the voltage drop across the resistor with; /archives//html/Amps/2011-08/msg00175.html (8,719 bytes)
