Review on AD584KH 4-Channel Precision Voltage Reference Module with Case - 2.5V/7.5V/5V/10V by Cedric Edwards
Amazing, inexpensive way to calibrate a cheap multimeter
After spending several months spending money on a reference meter, I discovered this gem. Here I now know that my meter cost is 0.4% lower than the cost of a reference meter or calibration service. How do I know it's safe? Well, google the properties of the chip.
