    Andy's archaic analog electrical test equipment

    Every year or two I drag out my old testers for a clean-up.

    Thought I'd share a few of them with you.

    This is one of my first clamp meters. It still works fine.

    This mega tester is over 20 years old and still going strong.

    And this one is even older and still passed calibration earlier this year....

    This is my RPM tester for motors. It nearly didn't get allowed on a site recently, the H&S brigade made me fill out a full 8 page risk assessment just for this tester.

    Dave please can you give the topic a more appropriate title...you can use your artistic license, I think the board did some kinda auto-restore cached text thing and renamed it

    Looking at that RPM tester, I'm not surprised they got you to fill in a risk assessment. I take it there's a direct mechanical connection involved
    The trouble with opportunity is it normally comes dressed up as work.

    I noticed you didnt add a the magnifying glass you use to see the readings on the screen (old age), could it be why you still use analog meters. These pics are just giving away your age, can you still remember how old you are? Do you own a stabiliser, to hold your cup when drinking coffee or do you keep forgetting where you left the coffee

    Good morning Andy,

    All this equipment reminds me of my dad's equiment. He practised as an electrician in the late 60's, the 70's, 80's and early 90's..

    Lol, thanks Dave, couldn't have titled it better myself and easy Ian...I'm not that old, mid 40's and can still locate my coffee although I do need glasses for most things nowadays.

    I keep meaning to get some new test leads for the ammeter but they're not even 30 years old yet so no rush I suppose.

    The rotation tester does require direct contact with either the motor shaft or the pulley wheels. H&S weren't very happy about anything that requires getting so up close and personal with the motor and belts. They insisted on the wearing of gauntlets, I declined suggesting this would be even more dangerous. We completed a risk assesment for the device and a separate one for the wearing of gauntlets. Eventually they caved in.

    I agree, I'm not a massive fan of digital instruments, they're okay if you need extreme accuracy but how often do you need a voltage or resistance reading to 3 decimal places which is kind of ironic when most instruments are only accurate to within a few percent.

    Digital tester have an extremely high input resistance which makes the prone to giving confusing readings. It's quite common to see a digital tester show 65 volts for example or some other random but substantial figure on a circuit that's actually isolated but because of capacitive coupling with adjacent circuits they pick up a surface voltage which is meaningless but confusing for the operator.

    Long live analogue!!!!!!!!
