What's the difference between a Fluke 87III, 87IV and 87V? Answered

The series designations are confusing me. A couple of the sites I've visited have mentioned the series V can withstand 8000V switching transients. But then, you never know when something is just marketing hype and all of the series can withstand 8000V switching transients.

I ask because I'm currently studying transient phenomena (LV), and will be working my way up to HV in the future.


If you're studying transient phenomena, you might want to consider an oscilloscope instead of a DMM, since DMMs have pretty rotten transient response... If you need to augment it with HV capability, purchase an HV probe.

I'm also looking for a HV probe for the oscilloscope I've been using. Do you have any recommendations?

I'm afraid not. The last one I spec'd out was about a ten years ago.

I *think Fluke used to have a couple of models, but like I said, it's been quite a while since I paid any attention.

good luck.

There are differences in display size, data logging capability and sampling resolution - I can't remember the details now, one set has a 20,000 count sample, the other 50,000.
