    People who don't know what they're doing with electronics should probably not use this on anything other than battery powered stuff.

    http://hackaday.com/2015/06/02/fail-of-the-week-the-deadlies…

    If it runs on 110v / 220v AC/DC, steer clear and don't probe.

    • effgee on 03/10/2016 - 20:34

      Well, you could argue that if you know anything about electronics, you wouldn't even buy one.
      That said, I have ordered one, to replace an almost identical unit the got unreliable over the years. 99% of its use is checking the state of my rechargable batteries

      No - I tried it the other day with 12V 100Ah. I could feel it getting super hot in less than 5s.

        And I got downvoted and my neg revoked in the other thread for saying that they're most likely unsafe, and you should spend another ~$5 and get a known good one from Jaycar.

          @Maverick-au:

          You do not know about regulatory guidelines for selling testing equipment in Australia. All must satisfy IEC guildines.

          Are you some kind of hobbyist, because you don't have a very good understanding about the technical details behind these products. Such a cavalier attitude to something as serious as working with electricity.

          I don't? Perhaps I live in the real world and see the products that are for sale. Clearly you haven't dealt with Jaycar for long if you think that everything they sell is a quality item that is safe.

        No - I tried it the other day with 12V 100Ah. I could feel it getting super hot in less than 5s.

        What does the 100Ah have to do with anything? If you were testing the voltage it makes no difference.

          It has to do with the maximum power or energy that a battery can hold. Testing the voltage across something with that type of internal charge is dangerous and should be avoided unless performed by a professional with the proper equipment. It's most likely a high power device.

          Why would you use a $2 multimeter to measure the capacity of a battery? There are products that are designed to do exactly this and a multimeter is not the correct item to use to discharge a battery.

    I believe people should not be buying these if they're just using it to test batteries.

    Buy a cheap one from jaycar or just get a decent portable one from element14 or mektronics.

    If you open one of these up, you'll be sure to see a lack of safety standards being fulfilled by the manufacturers.

        Why? What should they buy it for?

        If you have to ask that question, then you have no idea what a multimeter is used for in industry. Capacitance, potential difference, DC biasing transistors by measuring BJT/MOSFET terminals, continuity indicators. The list goes on.

        Most people have no idea what they're doing when they measure the voltage across a battery. That does not tell you anything about the remaining capacity of the battery.

        Yet you advocate purchasing a cheap Jaycar one that will likely be no different inside.

        They are different and do not include AC voltage measurements with a high impedance. I know what is inside a cheap jaycar one and they satisfy IEC standards and are fit for the Australian market. Honestly, if you don't want to listen to a qualified engineer then fine with me.
        I use to spend hours of my day trying to make things cheaper, faster and SAFE for the Australian public and global markets!

          You're suggesting that measuring voltage on a primary cell is not a good indicator as to battery capacity?

    Fluke is my choice for serious work, true RMS meters are the industry standard, if you don't know what this means you shouldn't be playing with AC or multimeters as Fluke means quality, although I paid a fortune for mine but these cheap meters are good for the 5 minute battery check or quick DC circuit which isn't critical ie a solar battery or dual battery system etc

    For basic DC this will be fine, just use common sense and be cautious with it, just make sure you don't overload it

    Cat I is the minimum for working on copiers / electronics *protected equipment
    Cat II is for larger electronic equipment, tools, outlets more than 10m from the Cat III source or 20m from a Cat IV source (outside power line), single phase
    Cat III is for circuit boards / three phase
    Cat IV is for outdoor powerline work coming into a building etc

    Anything Cat I will be fine for office usage, Cat III would be my recommendation too but buy quality if you're dealing with electronics every day, your life is worth more than 5 bucks.

    Buyer beware.

    Certfied to work on 240v circuits and Restricted Electrical QLD Licence for copier work, so I know my stuff
    Just do not bring these onto a work site, you'll find yourself in hot water fast, or worse yet kicked off a site.

    Spend the extra money, $165.99 for a fluke 17B which is great for general usage, sure its more expensive but its Cat III rated and SAFE

    http://www.ebay.com.au/itm/Newest-FLUKE-Digital-Multimeter-1…

    OR

    $79 for the Basic Fluke 101, sure once again its more expensive but it wont kill you and meets Cat III Australian Standards
    It is an entry level meter, safe to use and basic, perfect for testing Higher voltage circuits

    Anyone serious will consider Fluke over these cheap imported death traps

    Don't test car batteries with these they are not rated for them, that's just silly.

  • fruit on 04/10/2016 - 15:16

    Let's be real the item is unsafe for the purpose advertised.

    Measuring range:
    Max AC Current:10A
    Max AC Voltage range:1000V
    Max DC Voltage range:750V

    Car battery testers have much thicker cables due to the Amperage.

    This item would be illegal to sell in Australia due to missing safety marks, the fact it's unsafe. It doesn't deserve a spot on OzBargain.

    • altomic on 04/10/2016 - 16:38

      ok

      umm.. your talking about car battery load testers or something? In which case the cables are required to actually carry significant load..

      measuring voltage shouldn't draw a large current through the device, and it fits within the DC voltage range…

      Not that I endorse this product, the lack of certification means that anything its 'rated' to is really just a hope
