• Digital Multi Meters - time for a new one

    From No mail@21:1/5 to All on Tue Feb 25 22:01:18 2025
    My Uni-T DMM has become flaky so it's time for a new one. I can't
    justify the cost of a Fluke but don't want bargain basement.
    Any recommendations?

    I've got a Neoteck NTK017C. Made in China of course but that seems to be
    mostly unavoidable these days. Unit itself works nicely.

    I've got a Fluke 73, had it about 25 years. Last week I noticed
    something rattling about inside. I went to open it, and discovered the
    ABS case was rotting away from the inside. The rattle was from a piece
    of screw pillar.

    Not really sure what's caused it. The battery shows no signs of trouble,
    and is 'Best Before March 2025' . It's still usable for the moment. It
    lives in the dark in my toolbox (always has done). Though I did notice I
    have a roll of self amalgamating tape in there ?

    I bought a Metex M2325 in the mid-late 80s (see Metex section in Henry's
    advert on p67 at <https://www.worldradiohistory.com/UK/Wireless-World/90s/Wireless-World-1990-06.pdf>)
    and it's still going well. I've never had any problem with it. I thought
    I'd paid a lot less (not at Henry's), but that £32 price is equivalent
    to around £72 today.

    Mark's Fluke is 25 years old, but biodegradable plastic is a lot older
    than that:

    I also got a Brymen DVM from Telonic a couple of years ago. Either the

    Decent quality, reliable. I haven't worked it hard though. The range got
    good reviews in EEVblog.

    $WORK got a Tenma DVM (presumably from CPC) quite a few years ago.
    Nice-seeing meter ... except that all the Voltage readings were out by a

    It got returned/replaced, of course. I am not singling Tenma out as a

    Maybe there's a divide by 2 resistor network and the lower one has a dry
    joint so it's just a series resistor in circuit instead?

    I got an AVO8 MkX with leads and calibration certificate as a Christmas
    present in 1979. Currently no 1.5V low ohms battery installed, it has
    had 2 since I got it. On it's second BLR121 15V battery which still works.

    I use a cheap DMM from CPC bought in 1998 most of the time.

    My UNI-T UT58 (Maplins circa 2005) seems to be fine,
    apart from the leads, where the plastic insulation is
    hardening and starting to crack and split.

    What is wrong with yours ?

    Yes, all are 4mm. Any from a reputable source will now come with the plug
    ends shrouded to protect from accidental contact with higher voltages once plugged in. Meter sockets have been compatible with shrouded leads for
    decades.

    Better silicone leads will also be abrasion and nick resistant, cheap
    knockoffs may be less so.

    Indeed. But not all shrouded leads are created equal.

    I bought a set to use with my DVM and they simply didnt work.

    Decent silicone meter leads aren't too expensive (the Brymen came with a
    set).

    Are the plugs on replacement leads all a standard size ?

    Thereby hangs a tale.

    Fluke bid for the first DMMs used by BT. "Meter, multifunction, 1A"

    We offered them the standard 8022A but they decided they wanted a
    non-standard 3mm connector which we supplied as a special. Charging a small premium for the non-standard parts. We kept getting BT engineers phoning to complain about them. Quite a lot of BT engineers drilled the connector out
    to 4mm and used normal leads.

    We were quite happy because the crappy leads that BT supplied kept breaking
    and engineering stores often ran out. When that happened the engineers just bought a new meter from us, at full price.

    Any recommendations?

    Thanks for the (many) suggestions. After much diving down a large number
    of rabbit holes I spent a little more than planned at the outset and
    went for a Brymen DMM. It's early days, but first impressions are positive.
