    Which used bench multimeter

    OK so I don't need a bench meter. My Fluke 87 and 77 are really good enough.
    But, I wouldn't mind a bench meter to live on my bench next to my scope and power supply to be always on and ready.
    And I don't need any more accuracy than my 87 but I wouldn't say no to more digits. That said, I don't want to spend a lot either.

    So, if you were keeping an eye open on Ebay etc for a good deal on a used bench meter, what brands/models would you watch for?

    Re: Which used bench multimeter

    Well a Fluke 8050A it can be a good candidate if you do not need more than 20,000 counts.

    Edit: I will add a picture of my meters, its model has its own strong points.

      I wish you would have posted this a few days earlier because I thought about it and decided not to get it, but I'm surprised it went unpurchased for such a long time.

      Shipping would have cost around $30 to Canada + $15 BIN.

        Re: Which used bench multimeter

        Thanks for the replies. I'll keep that model in mind.
        Quite a range of prices on Ebay. Any other models come to mind?

          Re: Which used bench multimeter

          I recently acquired a Fluke 8600A and I like it very much. It's a 20,000 count 4-1/2 digit meter like the 8050A, but it has an LED display (a proper bench multimeter should glow in the dark.) It also has auto as well as manual ranging. The 200mV and 2V ranges are spec'd at greater than 1Gohm impedance, I actually measured 10Gohm on mine. I find this very useful.

          These models are old, but volts and ohms and amps are still the same as they used to be.

            Cool, I'll keep that one in mind as well. I saw your 8050 LED conversion, that looks awesome.

              Another alternative if you want a multimeter that is always powered on is to buy a handheld Fluke 8000 series and use the A81" AC adapter.

                  Thanks, but I do want the form factor of a bench meter (should have mentioned that in my initial post)

                        Thanks. will do.

                        Saw one in Surrey BC for a good price. 3 problems. Descriptions says "Powers on" nothing else.
                        Seller has 0 feedback.
                        Seller has been on Ebay for 2 days. Yeah, maybe not.

                          Many old 8050As have the -01 option, which means they have NiCd batteries inside. The power supplies on these models use the batteries as a voltage regulator, so when the batteries get old and crusty the unit no long powers on, but the "Bat Chg" light on the front will light up. It's an easy fix to solder in some replacement cells, or you can modify the PCB to work w/o the cells.

                          Good thing is that you can get those units cheap, but it's bad that you will not be able to see if the LCD works, which is another common problem on these units. They 'bleed' and turn black.

                            Re: Which used bench multimeter

                            Primarily I was up to for an 8050A with battery option, and I did buy one with all the outside markings to indicate that is was what I was looking.
                            By opening up the meter, the PCB was had an modification by Fluke, which was converting the PCB with battery option in to a non battery powered one.

                            The seller told me that Fluke did some of those ( afterward modifications) so to please some large customers.
                            I did get an discount after my finding from the eBay seller, but the point is that I did not get an meter capable to operate on battery ....

                            The PCB with the inductor at the right replaced the charging circuit,
                            Which usually looks as one black box.

                              Ok Guys,
                              I cheat.
                              If it's worth doing it's worth over doing.

                              Way back in my deep dark past I used to work for a company that made automatic test equipment for the US Navy.

                              http://www.navair.navy.mil/index.cfm...sStory&id=3217

                              We had to have the very best equipment to service the items used on the VAST System.

                              That included every long string DMM available at the time.

                              25 years later I was able to afford one such meter.
                              The HP3456 is a big systems bench meter.
                              It also has a 6.5 digit display, true RMS AC section and a four wire ohms function.

                              http://www.flickr.com/photos/9010884...57628575273797

                              Use it mostly for fixing big ham radio power supply's. Measuring AC ripple down to the 'gnats ass' kind of numbers.

                              I think I paid $100 for it shipped on Ebay. I got real lucky, all of it worked.

                              Also look up the Fluke 8500 series, last time I looked they were up to 8508 or so. Again amazing instruments.

                              The HP3455 is also very good.

                              Had one of these for a few weeks 'way back when', this was a stunning bit of gear.

                              http://www.testequipmentconnection.c...0-51-80-90.php

                              Also look up the Fluke 8800 with the right options, that is a tough mother.
                              A Fluke 8300 is worth the effort too. It has lightening fast reading ability.

                              Hope this helps.

                                Thanks, Jack. I'll expand my watch list.
                                I'm not against overkill, as long as the price is right
                                I've read a few threads over on EEV, and some of the HPs gets good marks. The Fluke 45 is pretty, but not as well received, and it's a tad pricey.
                                I just noticed the 8050A only goes to 2A for current.
                                Not a show-stopper, but would prefer 10. The 8300 might be a bit big for my taste.

                                  Well, I went a bit overboard, couldn't resist:

                                  Just kidding! Holy crap there are some expensive meters out there!

                                  Actually got a Fluke 8840A for around $200.00 More than I was originally looking to spend, but looks nice.
                                  Will post some details when it arrives.

                                    out of all the bench meters in my college's labs, my favorite by far is the old HP 3478A... it has 4 wire resistance among other things.

                                          Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
                                          by sam_sam_sam
                                          I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

                                          I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

                                          repairing a Fluke 335 clamp meter
                                          by Baldbentley
                                          I am repairing a Fluke 335 clamp meter. After contacting fluke it appears there is no service manual or circuit board/ component list available. I have determined that there us a faulty PNP bipolar junction transistors shown in the pictures. I am having trouble sourcing this transistor. I pulled a good one off of the board and tested it with my component analyzer but I cannot find anything that matches the specifications. Any help locating this part or a replacement would be greatly appreciated.

                                          Thanks...

                                          Is it possible to test small ceramic disc capacitor with analogue meter?

                                          I read EBOOK of Testing Electronic Component and found that

                                          "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
                                          Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
                                          It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

                                          Is it really possible to test small ceramic disc capacitor with analogue...

                                          Fluke 289 multimeter not working
                                          by Pauldg1
                                          I have a Fluke 289 multimeter which does not work.
                                          Have anyone an idea what could be the cause?
                                          When I turn on the device only the green led is continuously on, and strange stripes are present in lcd screen. I can only turn off the device by removing the batteries.

                                          Any suggestions will be appreciated...
