[Elecraft] Useful DMM/Cap/Transistor Meters(THANKS!)
Just wanted to send a note of thanks for all the comments on a meter that reads capacitance and inductance. I should have asked this from the beginning. Cheers!

Re: [Elecraft] Useful DMM/Cap/Transistor Meters
Ron, I agree - the RS meters give a lot of value for the money. I have a low-end RS DMM that reads up to 10A. Doesn't have any of the other measurements you mentioned, but it was only $29 as I recall. And, it is quite a bit slower to read than the Fluke. 73, Mike - Original Message - From: Ron D'Eau Claire <[EMAIL PROTECTED]> Date: Wednesday, May 31, 2006 6:24 pm Subject: [Elecraft] Useful DMM/Cap/Transistor Meters (WAS: Just built AADE capacitance meter - great!) > If you're in the market for a new DMM, the mid-range Radio Shack DMM's > provide these capabilities as well.

[Elecraft] Useful DMM/Cap/Transistor Meters (WAS: Just built AADE capacitance meter - great!)
If you're in the market for a new DMM, the mid-range Radio Shack DMM's provide these capabilities as well. One time I suddenly needed a part for my Fluke and I was in the middle of building - my K2 IIRC. So I trucked down to the local RS store and picked up a meter to use in the interim. It's a real workhorse. It measures: Voltage, resistance and current, of course current up to about 10 amps I believe. You can plug a transistor into a socket provided and it'll report the type of transistor, the gain and identify the leads. Capacitance from a couple of pF to many, many microfarads. It has about 100 pF "stray" capacitance, but a 5 pF cap reads exactly 5 pF more than the stray minimum cap it indicates with nothing connected. Temperature with a probe supplied. Frequency through the audio range. Of course, it has front-panel contacts for critical measurements to avoid having the leads in the circuit. The only thing it doesn't measure that I want regularly is inductance. I have an inductance measuring device built from an ARRL "Handbook" circuit that uses the DMM as a readout. Quite accurate enough from a one or two microhenries up to several millihenries. I got RS meter about seven years ago, but I see they seem to keep a meter with those capabilities in the US$80 to $90 range in their regular instrument lineup. Yeah, I fixed the Fluke. The Fluke is faster. The RS meter takes about 2 or 3 seconds to produce a reading while the Fluke is virtually instantaneous. I compared them side-by-side and compared those with a third high-end meter I own and all three agree on Ohms, Volts and Amps across the scale wherever I've happened to check them within 1% or better. Usually they dial up identical values on the display when connected together. The slow speed of the RS isn't an issue for me because I have an old VOM (wiggly meter movement volt-ohm-amp meter) that I use for "peaking" things, or I use my o'scope.
