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 say obvious but apparently your ability to see obvious has some problems if you're asking such question. You can find connections and estimate resistance range without looking on a display of multimeter.

Uh oh -- I am not sure whether that passes the OP's bar for an "informed response"... :P

@joseph: It might be just me, but that requirement of yours comes across as a bit arrogant. "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.
