The question is simple.
For me it nees selectable threshold, selectable max voltage, nice buzzer, maiby selectable frequency.
Light segnalation, maiby blinker.
A little led for light the zone
Must fit nice in the hand, and have interchangeable second probe
For you?
-
Latching beeper, fast response. My 87V has both.
-
Have a look at kripton's collection of continuity tester circuits

I am satisfied with my Ag 34401A. :D
Time ago I used MY64. ;D
-
2 wires with 220 volts ac across them. sparks : contact :-DD
-
I use a continuity to get a yes/no answer to whether two things are connected, so I don't need adjustable voltage, threshold, etc.
I do like the latching beeper and fast reaction of both of my Flukes, my 179 and 16. I also like the fact that they use low enough voltage so as not to send semiconductor junctions into conduction, so they don't indicate continuity through diodes and transistors.
I like the V-Check feature of my Fluke 16. If I accidentally connect it to a voltage source of more than 4.5V (AC or DC), it will switch to voltage measurement mode and display the voltage. Without causing any damage whatsoever to the meter.

I use a 87V but thought you might enjoy seeing this early one from the 1920s in my collection:

If the red dot moves out of the window you have continuity.

Old analog Triplett meter is my favorite.
-
Fast response for a buzzer is a must.
I saw a meter many years ago that played a tune (don't remember or care what) but it took about 5 seconds to begin playing. The only use for the meter was that when it was turned "off" the display stayed active with a clock that was reasonably accurate.

agilent now do a multimeter with a tune that indicate the resistance
-
Tune or tone? I think tone. Though I could see a case for (2.3) Ohm on the (10R) Range.
-
yeah yeah tone bad english
-
If I understand correctly, I think Neilm's tester actually played a tune... :wtf:
-
Yeah, Agilent U123xA meters can do that. The pitch of the tone depends on the resistance they measure. It's annoying as f*ck, though. I just have it set to a constant pitch.
The power-on tune was also annoying, I disabled it the first day I got that meter. I don't know what the hell Agilent were thinking when they implemented that tune. :wtf:
Aside from that, it's a really good meter. The measurements are spot on and you can disable the auto power-off function. :-+
-
I'd like my continuity meter to measure continuity between the points I intended to touch with the probes, rather than the rather old-fashioned standard of the points I actually did touch. GET ON WITH IT FLUKE
-
Any of the ones built into any of my DMMs...
-
One that goes "beep" when it detects continuity between the leads.
-
Old analog Triplett meter is my favorite.
For me too... :-+

My vote is for my beloved Polar Toneohm 550. It's tone varies in frequency as the resistance changes and is great for tracking down those elusive shorts on a PCB.
-
ideal:
be able to set current and max voltage.
fast obviously, and a tone that gives you info about the voltage value. freq == voltage

Oh, that is just beautiful. Hmm..... I am a massive cheapass, so I don't think I'm going to spend money on a continuity tester, but I think you've just added one more weekend project to my long list...

Voltage up to 1000V so it can be used as a megger :)
Current up to 1000A so it can be used to test bus-bar / connection
Last but not least adjustable sound level :-+

Hi guys
I am in the process of writing a review of the Fluke CNX multimeter and has just tested the continuity tester function on it and compairing it to other meters.
I have tested the shortest time for an good beep and here is the results..
Fluke 179_____________________0.49 ms
Fluke CNX 3000 Multimeter_______0.68 ms
Fluke 789_____________________0.88 ms
Fluke 287_____________________1.17 ms
Fluke T5-1000_________________4.05 ms
Fluke 27_____________________69.05 ms
Fluke 8846A__________________79.06 ms
I dont have a 87V so i can test that time, sorry.

My ideal continuity tester is one where god speaks to my inner conscience telling me "they are one"

That's a good idea.
