2019-11-25 Fluke Meters, My Experiences

From conversation with Bill Sherman 2019 Nov 25

I had my new Fluke 75 for a year or so and one day I turned it to the off position but the display didn’t go off. I tried it a few times but the only way I could get it to go off was to remove the battery. I checked the pamphlet and it said it was under warranty for 3 years. So I sent it back to Fluke for repair.

When I got it back, I found instructions online to convert my 75 to a 77 by changing a jumper inside. So now it’s identical to a 77.

Then the HVAC guy at work burned out a yellow 23 – looks the same as mine. But it’s not worth repairing, I just have it for what I could salvage, probably just the case.

Then later I bought a B&K autoranging meter. I like it more because it has frequency up to 2 MHz and capacitance. And it’s auto shutoff, too. I must have a dozen cheapo $5 DMMs from Harbor Freight lying around, and I use them more than any others. 🤔🤔

The first Fluke meter I used back in the mid 1960s was a big Fluke differential voltmeter. It was like having to null a wheatstone bridge – took awhile but it was a lot more accurate than an analog meter.

The second Fluke I used was a 8600 bench DMM that a neighbor gave me in 1975 because it was dead. I had to replace a +- 15V regulator chip, and I used it until I got the 75. So both Fluke DMMs that I own have had to be repaired. 😮☹️

But the Fluke DMM that really made Fluke popular with techs was the 8040 series. I got one of those at work and used it for many years and it never had a problem. Somewhere during one of the moves we had to make it disappeared – probably stolen by someone.😣😠
