I'd be more inclined to trust the Fluke as having the best absolute accuracy compared to almost any other meter out there. They are quite surprising when it comes to calibration. I've never seen one actually outside cal other than one that got left outside in the rain for a month and all that needed was an isopropyl scrub on the high impedance bits of the PCB.

If you're not sure, I would grab a cheap AD584 voltage reference from ebay or aliexpress. Usually cost £5 to £15 inc delivery depending on where they are arriving from (might take 2-3 weeks from China) and features. All just as good. That'll give you a certain enough for 4.5 digit meters reference to check everything against.
