Hi, I recently bought a multimeter with a description in the instruction manuel. It reads something like this. On continunity check when you have less than 40 ohms the buzzer will sound and a green led will light. Between 40 and 60 ohms no buzz but a red led will light. Above 60 ohms nothing will happen. I check this and indeed this is what happens. The manuel says nothing more, since its not the instruction type, just the fact. My question is: what is the meter trying to tell me beside the obvious and how is it useful in finding faults in circuits? Informed responses please. Thanks. |

You can find connections and estimate resistance range without looking on a display of multimeter. |

"Posters less smart than me need not apply." |

Sorry it was not ment to exclude any responses, just to have people who are interested in the post not respond but to follow along if interested. |

My meter beeps when measuring less than 40 ohms to warn me that the measurement is almost a short circuit. |
