Fluke 79 DMM
Hi all,
The Fluke 79 from user Lighting arrived earlier today - many thanks! This meter had an episode with a microwave oven magnetron so I wasn’t holding a great deal of hope for it but I do like a challenge… As it turned out it only required 3 components to get it working - definitely a testament to the build quality and ruggedness of Fluke gear. Short circuit bridge rectifier, open circuit input resistor (note these need to be replaced with the correct fusible flameproof type) and the 1A input fuse. Checked on a calibration machine and all well within specifications. Cheers, Kev |

Re: Fluke 79 DMM
Good work - I hate to think how many faulty meters get junked for the lack of a little investigation.

I did a 79 a few years back that an electrician had used to try and measure the output from an insectocutor, same result.

Re: Fluke 79 DMM
My Fluke 11, my mainstay for 30 or 40 years has just packed up and the LCD screen is disintegrating so I'm looking for a secondhand one now. I found mine almost indestructible
its measured the resistance of the mains on a number of occasions and it just shouts at you and goes on working. Having been long retired I will not use it much but its indestructability still appeals to me. Peter |

Re: Fluke 79 DMM
I'm glad to see that this meter went to a good home, well done on getting it going. I have quite a few Flukes here and there always the first DMMs I reach for. Made to last.

Re: Fluke 79 DMM
Thanks for that but I have just bought a Fluke 25 for not to much money, I'm amazed that the displays are still available.

Re: Fluke 79 DMM
So pleased you gave it a new lease of life.
That meter was my faithful companion for twenty years and probably 10,000 service calls. May it last another 20 years ! The display was still good on it. |
