I bought a multimeter long time ago
-
One of the more likely failures, in devices that have power supplies, are the electrolytic capacitors in the supply. My ex-boss (I'm retired now) had 2 TVs fail on him and both failures were from the electrolytic capacitors in the supply. He was able to fix both TVs by replacing the capacitors. Normally, the bad capacitors are bulging.
now I recalled my initial purpose: :java:

Just for checking fuses with the ohm meter is worth it. I have a garage door opener that is out of support and to replace it would require a total rebuild of springs, etc. plus the cost of the new opener. It had a well designed control board that needed 2 pop-in fuses replaced. $10 versus $400 dollars.
take notes here:thumbsup:

How about kelvin?

The problem with "cheap" multimeters - the test probes do not last.... And how many use the interfaces I/O ability to test transistors or even diodes? The old war military philosophy still applies - "unplug the faulty module and replace it , throw the bad one away ".
Buy a Fluke, they last forever and the leads never break, plus auto shutoff to save the battery. I have 3 different flukes from when I was a data communications contractor, even one to read amperage drawn on power cables because I had an electrical contractors license as well. I haven't tested a transistor since my Xerox days in the 80's, or Mosfets for car audio amplifiers. Never tested diodes, because most AC to DC converter chip have them built in.
If it ain't broke don't fix it Discover my world at jkirkerx.com

I plan to test some computer parts, but I did not get time to do it. now my refrigerator did not freeze, so I used it to test defrost heater.

I used to work for John Fluke Mfg. Co., Inc. who make the voltmeters most of you have in your toolbox. I have a hardmodel (manufacturing sample) Fluke 77 meter (which has since become the Flue 73 to make room for a unit with more features. This meter still has the same batteries in it as when it was new, and the same test leads. Interestingly enough, Fluke was bought by the giant conglomerate Danaher Corp., who made the durable test leads for Fluke meters. Tektronix, makers of the oscilloscope you probably have on your bench, was also bought by Danaher and folded into Fluke, so these two one-time competitors are now divisions of the same company.

I've always had a multimeter (VOM). Simpson was the best of the best 50 years ago. I keep one in each of my tool boxes, my desks, and my workbench. Oddly, one of the best I ever bought was a little Radio Shack multimeter that fit nicely in my briefcase and I could take it anywhere, until 9/11. I lost it somewhere about 10 years ago and have never found one that worked as well. I have Fluke and several other digital units but they just don't have the same old feel of the Simpson.

Does everyone, (apart from me), have a multimeter? :confused: Why has no-one told me! I'm, obviously, going to get right on it. Ebay or Amazon? I feel, somehow, that another one of life's opportunities has passed me by. ;)

Heh, yeah, I bought a multi-meter for my PC tech support tool kit then never used it for that. I have however used it to test suspected components on my own system and for testing power supplies for various other devices.
