    boiler elements, how to test?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    One for the sparkies / electrical people

    is there a simple way to test a element out of the machine? I am not meaning to plug it in, but can it be tested with a multimeter?

    If i have a 2600w element what should it read on a mm?

    i thought they were tested "under load" but not sure.....

    its out of a new "project" ::)

    Hi Leeham,

    Very simple mate I always just ask an adult.

    Good opportunity for the blind to lead the blind here.

    If you have a mm why not measure resistance ( R = ? )

    [element resistance changes with temp just to complicate]

    plug into V = IR then scratch head

    Now ask Q. but dont wait for answer, continue friggin about

    Wire it up put into water and give it 240 does it warm up? did it blow fuse? did it kick the core balance relay out?

    Now that should equip you to be patient for a short time.

    This approach always works for me, or I forget the Q.

    Obviously nobody else should try this as is part of a patented protocol, I use exclusively, I call it "The headless chicken protocol" a real winner.

    Kind Regards

    If you put your Mulit meter on resistance test.

    If it reads open circuit then no good.
    Should read about 22 ohms.

    hey no adults are at home to ask, i am a latch key kid skipping school and wasting time on CS by post-whoreing threads ....... :D

    I spoke to Jetblack as i went up there for a walk for a coffee :) (and to look at the bling they have), yes MM can test and i thought you could (and have one) but i did no what R (or what) to expect......
    or if it needed "load" to show a possible short etc

    seems ok, but its tripping the fuse, i just think its to much on the circuit and need a new 15amp line to the new shed :)
    who would build a shed without a dedicated power line...... >:(

    keep on tripping :) KT

    Make sure no power to sheath reading (ohms)
    or you may need a mega electrical tester ( just a small one costs RRP around $1000 ) for full compliance.

    Mal,
    I use Websters, I see you use the Oxford.
    Trouble is the pun doesnt work with the Oxford.

    In this case KT, Websters is actually wrong.... :P

    The Megger has never been called a Mega by the company who invented it and continue to manufacture it to this day. Perhaps the alternative spelling is being used by another manufacturer in the hope of avoiding brand registration issues, I dont know really.

    Cheers,

    Hi Mal,
    Your right Mal, my mistake, I never saw it written, and my electrical mates are very sloppy communicators,which I have taken a step further, I cant even find my Websters to recheck.
    It does sound almost right though doesnt it.
    What about 3 out of 10 for not completely wrong.
    Kind Regards

    Even with the right test equipment, people with out the right skills and understanding can kill / hurt themselves and others..


    Not every thing you read as to testing and what worked for one person will translate to your situation..

    If in doubt.. Get a professional... *


    Just because some get lucky and may have safety systems installed... They are not 100% and will not protect from an hook up across Active to Neutral (where your well insulated) and some places do not have any core or elcbs installed...;..


    Remember, while many may post what they have done and or near misses... *A few on CS have posted, and one not so long ago ( I wonder if I might still get the dead unit) experienced less than ideal outcomes......

    However, how many times can a DEAD person post; to tell about their mistakes...

    Had to get a so called Handy Man to hospital today (in mel) as they got hit when trying to remove a jam from a laser printer.. Yep they overrode teh safety locks.. *They could still not understand that 240V in could be so HOT and that some one would put a cct in that generated many more Volts... *

    Stay safe... If ya not skilled / qualified and it involves Electricity - leave it alone..

    Mind you, there are a few that I would gladly disable teh safety switch for, as it would soon prove Darwins theory.

    I used to be the "printer god" at a help desk a few years ago.
    Ive never had a shock un-jamming a printer.
    They must have really had no idea what they were doing.

    They had their hand up and in side and ended up with burns to their finger tips...


    One of the later Cannon laser printers.. Looked like they got their hand in and then tried to turn it on.. With hand still inside..

    Darwins theory... If ya think you have made if fool proof... Let an over confidant person who thinks they know better and who has access to the web... They read it some where ???

    Thus my post it to remind people that Electricity is dangerous.

    Dunno about Darwins Theory but they may be a potential nominee for the Darwin Award (presented to those who reduce - and improve - the human gene pool by acts of utter stupidity)
