    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.

    Oh yes. Checking fuses, batteries, temperature, ... the list goes on. I have several: two digital (so I can check the batteries in the other - and one has a current clamp the other doesn't) and a pair of Avo 8 analogue meters.

        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 ".

          Cut it in half and throw it away - I learned that with cables decades ago. It you don't, some bugger will fish it out of he bin and it'll come back to haunt you ... :~

                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. ;)

                  Why buy a multimeter? Surely one would have done the job.

                      Ain't that the truth. I had a multimeter that I bought in the early 1970s. Of course, from that era, it was still an analog meter with a needle. This is it (at the Radio Museum): Multimeter 200H Equipment Central; where?, build 1973 ??, 3[^] It lasted me over 40 years but it was the probes that wore out and I found I could buy a cheap new digital multimeter for less than the cost of a new set of probes. That digital meter lasted me 5 or 6 years and then those probes wore out and again it was cheaper to buy a new meter than to get a replacement set of probes.

                                  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.

LOL Now I have a talking meter with a nice female voice. I never knew how freeing is a talking meter till I went blind. thanks for sharing... chuck

                                          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.
