Greeting all, I wish to sell my Wavetek branded 1281 with options 10,20,30,70,80. These options comprise AC, Resistance, Current, Analog output. This instrument has been in my lab about 8 years, used only when needed, so the displays are bright. Fully functional, and I have replaced all the aluminum electrolytic caps in years past. I could never locate a cal key, so the lock has been removed. I have maintained it with my 4800A, but have not re-cal'd in the last 2 years or so. It does need a careful, complete re-cal, with good standards. But, it is still within 1-2ppm of the 4800A after full warmup on the 10VDC range. Included are photocopies of the manuals Price is $2800 plus shipping and insurance. Pictures available on request. Bob 360-601-2802
