They don't claim it to be. Actually the set voltage has a tighter specification than the readback voltage.

It was my impression that the readout was specced more accurate (0.05%+10mV instead of 0.05%+20mV for programming). It is also my experience (after calibration).
Note that the programming side takes several minutes to be stable, so expect several mV differences between cold and warm.
Armxnian:
The data sheet says the set voltage accuracy is .05% ±10mV, and the read back is .05% ±5mV. So theoretically the read back is more accurate, but both are always in spec so it doesn't matter.
Also I'm not complaining, just sharing observations. The unit is awesome in performance and bang per buck.
H.O:
Yep, I got that backwards.
Programming is 0.05%+20mV, readback is 0.05%+10mV (on Ch1 and Ch2). Sorry about that!
Armxnian:
Where does it say 10 and 20mV offset? I see 5 and 10mV under annual accuracy.
