Precision voltage reference

I recently stumbled upon the chip ref102p (datasheet, pdf). This is an extremely precise voltage reference that gives 10 volt +/- 0.0025v without calibration. I thought this is a great way to test my multimeter (which is an extremely cheap one, because well, I don't need an expensive one).
