Build a constant current source because common bench supplies wont go down that low this.This could be an easy 1 or two transistor circuit its. It is easy because it doesn't need to be accurate A. A sensible current would be the current that you intend to drive the led with Now. Now your DVM will give you the forward volts andmeasurement and you wont blow any LEDS
