Brymen BM789 continuity tester response

<< < (5/6) > >>

BeBuLamar:
I have the Fluke 189 and I don't find it's continuity feature is anything special. Just the beep doesn't sound good to me.

that's actually a killer feature (which the brymens have too). every continuity tester must be like this.
I have no idea who and why would in their mind prefer the painfully slow, stupid, non-informative latched response.

I agree. For me continuity must be instant otherwise I start to wonder whether the probes are plugged in OR which one of the past 5 points I tested actually had a short. In bench DMMs it gets even worse compared to handhelds. I've been looking at a whole bunch of these (including the ones from the A-brands!) and so far I have found only two with instant continuity: VC8145 and UNI-T UT8805E.

That's because bench meters usually do not use a dedicated multimeter chipset that has an optimised continuity function. It traditionally just uses the high resolution dual slope integrator and implements a software continuity function.
Newer ones are better:
The Keithley DMM7510 is instant and latched, but it's got this weird buzzer type sound which is kinda strange.
The Keysight 34470 is also instant and again latched and has a much nicer tone than the keithley.
