Multimeter Calibration and Voltage Referance


It would be interesting to know how members go about and keep in check accuracy of their workshop multimeters. I have 5 multimeters and each is giving slightly different results. It would be nice to calibrate them to a known voltage standard.

Of course I could pay the money and have them calibrated with the certificate but I am just wondering if there is an easy home made method to address this.
