It took me more than a year before I tried to light up an LED - and I probably wouldn't do it again for another year.  On the plus side, it actually won't happen again, because every time I pickup the meter now the earworm of "oh yeah - this doesn't light LEDs" pops into my head.  Even though lighting up LEDs was (until that moment) the furthest thing from my mind.  (Cripes - I just wrote an entire paragraph about lighting up LEDs... :palm:)

I think we might be on to something here. In our next session, I'd like to explore if your obsession with lighting up LEDs may be linked to your childhood in some way. But I think that's all the time we have for our session today.  :-/O

It's an important function for many people. Some meters even have special "LED testers" on the front.

Me? I wouldn't buy a meter that can't light up a big white LED.

I'm for hire.

It could even flash the battery warning indicator at you in that mode if it makes the designers feel better.

Makes me imagine some future Dave multimeter review:

A special LED test socket may be a safety concern (Probably not on the Fluke).
A diode voltage that can light white leds can sometimes be useful, I have two meters can optionally use considerable higher voltage for diode testing (121GW & CA5293) they are most for testing zener diodes (I have used the higher low current voltage for other purposes also). There are also isolation testers that can use up to 1000V for ohm test.
Generally I would recommend having multiple DMM's and not all of them need all the functions.

But... it's yellow! He can't say bad things about yellow meters,


It's not much use for testing star LEDs though...

If any sparks are big enough to come flying out of those LED test holes then you've probably got more important things to worry about.
