Hi, Just found something interesting.
On my old salvaged 2G base station (don't ask!) I found a chip which looks a lot like a REF02 and from memory this is indeed a precision IC. Can these be salvaged and put to use? I found them on greedbay but due to my chronic cashflow problem will have to wait a bit before buying some. For my purposes (boo hiss!) 4SD is fine ie 1.0186 volts Although for the sheer heck of it I might ovenize the chip(s) and make a proper temperature compensated "Weston" source. My current meter seems accurate despite being inexpensive, its a pink one purchased on promotion from MUG. However it does deteriorate if the battery is low hence a need for a reliable voltage standard to go with my atomic clock (see above) _______________________________________________ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
