Hi Guys,


I am looking for a simple, standalone continuity tester. 

Must have a loud buzzer, lol.

It should report a close connection when the total resistance is below 1 ohm, would be great if that can be adjusted.
It should also use very small currents for the test, don't want to break any potentially still connected components.

I did a google search and didn't see anything ...

Yes, I have several multi meters that can do that, but they are typically occupied doing some more serious work,
and most of the I can't hear the efing buzzer ...


Any pointers, suggestion?


Many Thanks,
luudee

I am assuming you mean Continuity Tester

Martindale,

* TEK402
* Probe voltage: 9V DC approx
* Test current: 5mA
* Continuity range (audible): up to 10k: nominal
* Audible output level: 85dB minimum at 30cm with leads shorted
* Overvoltage protection fuse rating: 50mA, 250V, Fast Acting Ceramic Fuse,
* TEK404
* Probe voltage: 9V DC approx.
* Test current: <50μA (across short circuit)
* Continuity range: 0: to 2.2k: ± 10%
* Audible output level: 85dB minimum at 30cm with leads shorted
* LED indication: bright orange LED Buzzer and LED intensity reduce with increasing continuity resistance

Yes, indeed ! I did mean "Continuity Tester", thank you for pointing that out !   (I fixed that now in my post)

And thank you for those suggestions !

That's a long way from 1 Ohm...
