stays put
shallow and transparent so it is almost invisible. sticks and stays put. I can detect no creeping but I don't use it for furniture either. I use it for small boxes.

Good DMM
Full featured and accurate. Internal temp reading is also very handy.

Uncertainty of less than 2E-10 against GPSDO
1 of 1 found this helpful I got two of these. Both worked great anday with less than 2E-10. I updated the time-base of the clock that I built around venerable MM5314 clock chip decades ago with one of them. With such an accuracy, my lifetime will not be enough to see it gain or lose 1 second! ;-) I'll keep the second as a spare. Seriously, I locks fairly quickly: it counts up and down once before it smoothly acquires lock. It won't let go afterwards. Lock indicator goes low and stays low. Fascinating to watch!
The best part is that it works from a single supply, 12V (13.8V) is just fine. it takes about 1.5A or so at the beginning until it warms up, slowly dropping down to 0.8A or so.
A GPSDO would be more accurate but only if it sees good constellation and if PDOP is low. You could trim or calibrate this Rb unit with its EFC input but why bother? I am very happy with this Rb based oscillator. Small, self contained; easy to use.
