>From Lee Jones, off list, by permission: > I'm looking for a truly credit card sized multimeter. Radio Shack (US) used to have some pretty small voltmeters. I've been carrying one in my valise for about a decade. It is credit card size but about 1/2" thick. Leads coil up inside the top cover. As I recall, it was $15'ish. It tends to be a little flakey, but it's great for rough voltage or continuity checks when your real toolkit is a half hour driving time away. Overall, it's worth carrying. I think they used to have a much thinner one. Quick check of www.radioshack.com shows that 22-820 appears to be the smallest one they now offer. Dimensions are not listed; it just says "shirt pocket" size in owner's manual. It looks like an updated version of what I've used for years. And it's now $30.
