Need a multimeter that will display PEAK values... please read.

[slugg]

I'm looking into working on a project that would require a tool to measure and display the peak voltage, current, or resistance in a circuit. The reason why I'm interested in peak values is because this circuit will only be engaged for roughly 100 ms at a time. That's too fast for my nerdy eyes to see and react to with a traditional multimeter

Any recommendations?

I would ordinarily say just use a Fluke with a MAX/MIN/AVE button... but 100ms? My 112 only displays 4 samples/sec so that's probably out.

Can you get a cheap digital scope?

Picoscope!

Some signals may be even shorter... like 50 ms.

Bobsmith, do you have any experience with Picoscope? Which model would you recommend?

 

[bobsmith1492]

I used one a little but it was an older model. The software was a bit finicky but it did the job just like any oscilloscope.

I'd go with your budget; the cheapest one (the one I linked) will work for your application; it just won't do you any good if you have any high-speed data in the future, that is, anything much over 1MHz.

Not cheap but the updated fluke 287 model the 289 can do that it tops out at 250us minimum for transients

What voltages are these going to be at ? I assume it is DC ?
If it is at logic levels then I like the bitscope over the picoscope.

Aren't there some analog units whose needles stay at the peak value?
