What does the acronym DVA mean? I've seen this mentioned in regard to testing outboard motor electrical circuits.

DVA means direct voltage adapter. It's just another name for a peak reading voltmeter. The one I have is made by Stevens instruments. It's different from a standard voltmeter in that it's designed to read voltages that are not constant. It reads the peak or highest voltages from a source that gives a voltage that rises and falls. For OMC and other brands of conventional 2 strokes it's required equipment in service manuals for testing ignition components.

Thanks--I am totally familiar with the term peak-reading voltmeter, but had never encountered a "DVA" in 30 years of working with electronics. I guess the "DVA" acronym must be unique to the outboard repair industry. There was no acronym listed for it on the usual reference sites. Cf.:

DVA = Department of Veterans Affairs, and 55 others

Since they came out for OMC motors back around 1977, they have been called either DVA or Peak Reading Adapters.

Here is a link to an inexpensive DVA for checking CD igntions and J-E tachometer signals.

Thanks for the information on the meaning of the DVA acronym.

Based on some additional information I received, I deduced more about the DVA device itself. The DVA device is used to convert AC voltages and pulsating DC voltages of various frequencies into a steady DC output voltage which can be read on a standard DC voltmeter, and apparently the DVA device is often used with a FLUKE digital multimeter. The frequency range of the AC voltages is generally quite low, say less than 10-KHz and down to nearly 1-Hz. The so-called DVA device is apparently in common use by outboard motor repair technicians. Readings taken with a DVA device show good correlation with the values published in OEM service manuals which were taken with specialized test equipment that was recommended or sold by the manufacturer.
