With all due respect, I would not get that one. It is scaled for measuring rather high voltage. Also, be leary of DPMs where they specify the resolution, but not the accuracy percentile. This one sports a resolution of 1V at 600V. That means it can tell the difference between 600 and 601 or 599, but no reference to how accurate that actula voltage reading is. I'm sure the UK has surplus houses like Alltronics, MPJA, Surplus Sales, etc. also. Just a matter of finding the right site. If you know of a neighbor who is an Amateur Radio enthusiast, ask them. They always have the scoop on stuff like that. I know, I've been one since 1971.Originally Posted by sideeffect
You can't hurt a motherboard by simply probing points to determine where to get voltage readings as long as you don't slip and short out two adjacent conductors. Missing electrolytic capacitors are alwyas a good starting point as they are usually situated after the PWM circuitry and often close enough to the destination so as to give an accurate reading.
A lot of people make the mistake of using any point on the chassis as their meters return path (minus lead). That is not a good practice and the accuracy of the reading can be compromised. The more current the particular voltage you are looking at is drawing, the worse the error will be the further you have the probes from the load when taking a reading. You can thank Mr. Kirchoff for quantifying that phenomenon (Kirchoff's Loop Law).
