D.V.A. & Multimeter Question

[sshawn09]

Why is it that it is recommended to buy a D.V.A. (peak hold) adaptor for the multimeters, when the multimeter might already have peak hold?

I recently obtained a Fluke 88V and its got the MIN/MAX and peak. I noticed that alot of websites sell the 88V kit that includes a DVA adaptor. Why is this?

Thanks,
Shawn

Re: D.V.A. & Multimeter Question

min/max and DVA are not the same thing.

Are you in boat school right now or something?

What a dva does essentially is slows down and stabilizes the voltage for the DMM to read. Permanent magnet electrical generating devices (such as a flywheel and capacitor charging coil) throw out a rather erratic voltage that a multimeter can not read. It's not a stable voltage. If your try your meter without a DVA you'll get some kind of reading, but not that actual PEAK voltage that your looking for.
So it's not that it's recomended that you get a DVA... you absolutely need one if your going to work on outboards.

Thanks for the reply. So even the peak or avg feature of the fluke wont cut it either?

I'm not a marine student, just a hobbiest that was sick of his harbor freight multimeter, and admired all the features of the fluke 88. Also I have an old evinrude that is sick in bed with the flu.​

Nope, it won't do it. I own an old fluke 8 and the same fluk 88V. You need a dva with both meters. The only meters i know of with a built in dva are the ES530 and Stevens instruments. makes a strictly only dva.
