Don I have indeed looked at the usb instruments. Pretty amazing for the costs actually. But I have been fortunate to get out of the epay drug before $ went crazy. (A better observation was I did not like the $ for the junk and risk) Also been lucky to stumble into reasonably priced broken gear. So my heavy duty stuff is great. Still with a handful of these USB sensors and instruments my bench would be 1000 LBS lighter and the power consumption 20 watts. I could easily acquire and store information by the tons with modern laptop technology. But I like the accuracy of the HP stuff. Regards Paul WB8TSL
