| Why do we want fast continuity detection in a multimeter? |

If you only do it occasionally then you can do it a bit more carefully. --- End quote --- Having used both meters with fast and slow continuity, the difference is not between sweeping fast and slow, but the difference is between sweeping across a row of pins vs deliberately touching each pin in sequence making sure you pause at every pin. Because sweeping slowly across a fine pitch device is likely to still go quickly over some pins. |

OP already has two meters, one that he says isn't slow. (and I'm not seeing that this meter is...) |

One thing that that I'm not sure has been mentioned before in this thread is that cheap meters often come with terrible probes. Quite a few youtube reviews show meters that have terrible continuity response with the provided probes but instant response when quality probes such as Probe Master are used. Often you can noticeably improve continuity response by just cleaning the probe tips with IPA. Both of those "fixes" have worked for me. I'd suggest first cleaning the probe tips with isopropyl alcohol. If you still don't like the response you're getting, consider getting some quality probes. You can get the basic Probe Master set for less than $30 shipped (to USA) In my experience and as mentioned before, the ZT-Y's continuity isn't instantaneous, but it isn't particularly bad (when good probes are used). (If you don't want to spring for Probe Master, these $6 generic Uni-T probes work well for continuity) |

There are no speed standards for multimeters other than watching a youtube review and speculation. A proper test would involve switching on/off a resistance and measuring response time at the beeper. Most DMM's clunk along auto-ranging which is the biggest time hog. Then the filtering and beep threshold time is there too. --- End quote --- https://www.eevblog.com/forum/projects/dmm-continuity-tester-v1-0-better-than-clicking-probes-together!/ --- Quote from: IanJ on March 31, 2022, 04:15:29 pm ---Example MARK Examples (minimum) at 250mS SPACE: - Brymen BM257 = 38mS - Fluke 85 III = 0.9mS - Fluke 87 = 0.9mS - Agilent 34405A = 25mS - Keysight 34461A - 1mS (needs Space = 300mS) - Agilent 34401A = 20mS, but will work lower but gives continious tone - Brymen BM786 = Better than 0.01mS - V&A VA38 = 0.1mS (beep varies in volume to point it's hardly audible though, obviously not using a fixed beep length) --- End quote --- |
