This just checks the low dc voltage accuracy which is in the ranges i use 99% of the time.
The Voltage Reference 2.5V 5.0V 7.5V 10.0V is set by just moving the jumpers look for "AD584 4-Channel 2.5v/7.5v/5v/10v High Precision Voltage Reference Module", and they only cost around $8 on eBay.
Checking the accuracy of my new UNI-T UT61E DMM on the low DC range.
I am running the Voltage Reference board from an 12v 1amp power adaptor from one of my battery chargers, they recommend using a battery for a more accurate result but i don't have any suitable battery`s
