3.1V is enough to light a white LED.

Let me know, when you will succeed in doing so with a Fluke 289:

DMMs can't do everything unassisted.

I had a bunch of LEDs to test with the Fluke 77.

For the ones it couldn't turn on, I just grabbed a half dead 9v battery, an appropriate series resistor from the junk box, & read the volts across the LED when it was lit,
Total cost of the "LED tester"------- zilch.

Metrix MTX3293 has 28V 10mA mode for zeners and leds... But not really economical to buy it just for that...  >:D

If I only had one meter, it would have to be a handheld. 

  I'd probalby get a Brymen 869.     If the 869 is out of budget, then a BM789.     

Fluke 87 is a good meter but it is too expensive.     Cost matters.  It always does.

Fluke 87V or 87 V max

I don't know about your white LEDs but here's mine, actually a bunch of them.  3.1V should light any single blue or white LED.
