    I went ahead and bid on a Fluke 179 on eBay -- probably overkill for what I need but having the mA option might be nice for the smaller amp wiring I do (stick switches to relays). Also has a temperature probe for some hi-tech barbecuing. Worried though that the 179 is really "mint condition" as advertised, but I'll take the shot at saving $200 -- Thanks for the advice everyone -- Andy On Sep 12, 2013, at 9:14 AM, Fred Klein wrote: > > Eric...I like your B Franklin quote...what say you about the unit sold by B & C? > > Fred > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=408492#408492 > > > > > > > > > >

    > Eric...I like your B Franklin quote...what say you about the unit sold by B & C? Fred B&C is trying to make a living and they are really nice people. If you really want a cheap meter, search "multimeter" at Deal Extreme. 1/3 the price and free fast shipping to your door. I buy lots of things from them. For LEDs, they can't be beat. For great LED flashlights, spend a few bucks with DX.com and be astonished. Some DX stuff is junk and some is amazing. Learn to take the good with the bad....it ain't worth sending DX.com stuff back. But for multimeters, I buy Flukes. My Fluke 87-V matches every digit of my Calibrators Inc. DVC 8500 Voltage Calibrator ($4500 new, 99999 millivolts. Ohhhh how my nerd heart leapt. But I bought it surplus for only $150!). -------- Eric M.

    Fascinating Eric...as in so many things in life, one can scratch a surface and find entire worlds... Knowing absolutely nothing about multi-meters, I thought your previous reference to "Fluke" was to an occasion when, just by a fluke, you came upon something unexpected and truly wonderful...I had no idea of the breadth of quality in multi-meters...

    Fluke is the way to go and is what I use. IMPORTANT!!! I keep a couple of Harbor Freight $3.99 ones around just to loan out. I learned this the hard way about 20 years ago.

    Before Bob flails me for suggesting more meter than you really need for most projects--I suggest: 1) Learning how to use a meter is more important than having a super-accurate meter. 2) No, not everyone needs a Fluke 87-V. I only needed it for one special project where accuracy was critical. I usually use my cheapo Fluke 77. 3) Meters, even cheap ones, are better than ever.

    Barry I agree with you on this one.- I bought a Fluke 77 way back in the early 1980s, when I was a fledgling engineer at Boeing Aerospace.- The sa les rep offered them to design engineers at the same cost that Boeing paid. It is still going strong and has proven itself many times.=0A=0AThen I dec ided to "upgrade" and buy a Fluke 87 V.- Turns out it was an upgrade, but I never got rid of my 77!- I love them both!=0A=0AI did do one thing tha t hasn't been discussed here (I think).- I replace the batteries on a reg ular interval with 9VDC lithium batteries.- I do this in order to prevent an alkaline battery leak.- Yes, I'm taking a chance on having a Dreamlin er moment, but so far the vibrations in my toolbox haven't produced a failu re.- I also place a vinyl label on the meters' cases that tell me when th e batteries were replaced.- Both were replaced on 9/18/2009.- I figure I have another 2-4 years on those batteries.=0A=0AI'm not going to comment on Harbor Freight, because I think most of their stuff is trash. :)=0A=0A -=0AHenador Titzoff=0A=0A=0A=0A=0A________________________________=0A Fro m: Barry Davis <bed@mindspring.com>=0ATo: aeroelectric-list@matronics.com =0ASent: Thursday, September 12, 2013 12:36 PM=0ASubject: RE: AeroElectric- List: Good Multi-Meter recommendation=0A =0A=0A--> AeroElectric-List messag e posted by: "Barry Davis" <bed@mindspring.com>=0A=0AFluke is the way to go and is what I use. =0AIMPORTANT!!!- I keep a couple of Harbor Freight $3 .99 ones around just to=0Aloan out.

    Subject: Re: soldering steel stud into lead clamp.
    Thanks for the reply Roger. I was concerned about a good electrical connection in addition to mechanical strength, that's why I was looking at soldering. I took the leap and soldered the steel threaded rod into the lead clamp. The rod went into a threaded hole that a setscrew was removed from. I cleaned the rod with a wire wheel and then acetone. Applied rosin flux to the threads and screwed it in. Using a propane torch I heated the rod until the solder wicked down into the threads. The clamp configuration provided a compartment under where the rod threaded in, which I filled with solderto increase the contact area between the rod and the clamp. Initial inspection and testing showed a strong bond. This isconsistent with how strongly a few droplets of solder adhered to the rod. A standard multimeter shows no resistance. The the major concern with this process was caused by the plating on the rod. I'm assuming it was either zinc/cad or galvanizing, based on the yellow/white residue from the heating. Heating either of those substances releases toxic fumes and theySHOULD NOT be inhaled. For further info research welding galvanized steel. Aminor concern was possible lead vapor from the heating of the clamp. In summary, it worked exactly the way I wanted. I will be keeping an eye on this and report any noteworthy developments.

    Well after careful consideration, the EICO Model 540 Readi tester Did anyone build thisback in about 1964 I still have mine! Any Fluke you can afford though you will never regret buying a good meter.
