content: I found a deal I couldn't pass up on Craigslist last night. Someone was selling a brand new Fluke 87 V still in the packaging for $200. I'm meeting the person tonight to do the exchange. What should I do/bring with me to test it out to make sure it works? I feel like I'll need a screwdriver and a 9V battery at the bare minimum to make sure it actually turns on and such.What kind of tests can I do that are relatively quick so I can try it out right then and there to make sure I'm not getting ripped off?

content: That's tough if you don't have a precision voltage reference (TI has free samples, but you'll have to wait to receive them in the mail) or another multimeter to test it against. You can test basic functionality out, but you won't know if it's in calibration

content: Check all segments on self test (Press and hold "autohold" for 87-V, Press and hold "hold" for 87 and 87-III)Select Resistance functionCheck lead resistance should be 0.something, lower is better. (not a dealbreaker, but make sure there's no flashing OL or anything.)Place red probe in ma jack ("wrong way") resistance should be about 1K. "OL" means fuse is blown.Place red probe in A jack - should be low resistance. (0. something)Check backlightBring a 9v battery and a 1.5v cell for a quick sanity check.*(the next test only applies to 87 and 87-III)Press and hold range switch at turn on for segment check - should get0 - AC volts32 - DC volts64 - DC millivolts96 - Resistance128 - diode160 - ma192 microamperesThat's what I can think of off the top of my head. I'm sure the meter gurus will respond shortly.* In most cases, if the reading is reasonable, the meter is fine. If it's been damaged, the readings will be WAY off. I suppose there's the very rare case where it could have drifted 2-6 percent, but I've never seen it. Every Fluke meter I've seen or worked on was either in spec (or very close for older meters) or was very obviously wrong. That is, you don't need a precision voltage source to check a meter in most cases.

content: Thanks for the info. I'll definitely bring a couple of 9V with me and probably a AAA battery. I don't want to get into the situation where they didn't bring a battery so I can't test it or anything.Will those values (0 - AC volts, 32 DC volts, etc.) cycle through when turning on?

content: I'm sorry I should have been more clear. First, I was corrected bellow by Retiredcaps - this test only applies to the 87 and 87-III. (for all future viewers of this thread)With the meter off, hold down the range button, and turn to "AC volts." continue to hold the range button down and note the segments should be all showing. (all uniformly dark) Then release the range button.You'll see just "0000" on the display. No units.You'll then see the other numbers at the other positions. My 87-III shows "-0032" at the DC volts position, and likewise, "-00xx" as above for the others. Ideally the numbers would be exactly as shown, the farther they are off, the worse condition the range switch is in. I'm sorry I can't remember more about this test.

content: Quote from: Excavatoree on October 29, 2013, 04:31:18 pmI believe the above only works on the original 80 and 80 III series. I tried the above on my 87V and it goes into smoothing mode.For safety reasons, I suggest you meet the seller in a public area. Carrying $200 cash for a transaction that may or may not be real could lead to negative consequences.

content: Thanks Retiredcaps, and I'm sorry to the OP. I swear I remembered doing that test on my -5. I don't have one here at work, so I was going to check when I got home.I guess I need to start taking notes - my memory about the different models and versions isn't as good as it used to be.

content: Alright, I'm back!Deal went very smoothly. Did all the tests here and it passed with flying colors. The DMM was exactly as advertised, brand spanking new. I couldn't be more happy with how it went. Apparently, the guy selling it was going to start a HVAC company (which is why he got the 87-V...for the TC capabilities), but ended up getting a job offer from somewhere out of state, so he decided to sell stuff off he didn't want to bring with him.
