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. |

But not really economical to buy it just for that... >:D Let me know, when you will succeed in doing so with a Fluke 289: Cheers! ;) --- End quote --- |

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 jon |
