| Seriously, anyone know the story and meaning of "OL" on multimeters? |

Surely it means "Oh Lord" - given I most often see it on a continuity reading and I now have an open circuit to find in a bunch of wires |

Early DMM display a 1 for this. --- End quote --- Nixie (or other early digital display) multimeters have indicator lights for "Over Load". I'm assuming LCD DMMs in the 80s soon followed. |

Some of them spell it out for you. |

It isn't up for a vote. Read the manual. |

I repeat the important bit mentioned above: "OL" works nicely on 7-segment displays, but "OR" is perhaps harder to read. |
