      Turn the selector to the clamp mode Plug the optional clamp meter inputs into the positive and negative terminal of the multimeter. That's it !

    I think having a current function on the voltage jack is very impractical and maybe unsafe.

    • @KeepOnTesting
      @KeepOnTesting  3 ปีที่แล้ว +1

      Yes, having the current input on a separate circuit is definitely preferred.

    • @KeepOnTesting

      Definitely! Its a hugely popular OEM... here in Canada, the LIDL equivalent is Canadian Tire / Mastercraft brand, .and AllSun is the OEM as well.

    i have the old version the circuit inside is the same probably and if you wanna buy it forget about measuring amp and temperature because it wasnt working when i bought it also, i think it is common in this device but hey other things work relatively ok if you are a new one in electronic it is ok...

    Actually, I kind of like Allsun products. I bought their "Auto Electrical System Diagnosis Device". That's pretty much a poor man's Power Probe. What can I say about it? Well, it works. I saved myself double the price of it the day I got it. It's not nearly as sophisticated as the actual Power Probe, the leads are a little cheap but...it works!!!! I've used it to diagnose problems with trailer lights and radiator fans. One day when I'm flush I may buy a Power Probe with all the goodies, but in the meantime, the Allsun is great. And yeah, I love the box!

    • @KeepOnTesting
      @KeepOnTesting  3 ปีที่แล้ว +1

      Allsun can definitely surprise..they do put out some great test instruments..unfortunately they have a so-so track record in the QA department but this was a decent offering..👍 also they are the OEM for alot of other brands.. !

    I have EMOS EM420B for 4 years now, but resistance started being wonky 🤣😂. uF is okayish, diode mode same as yours. It looks exactly the same as yours. So because resistance meeter "died", I got EMOS MD420. Few little changes, probes the same but probes covers has a hole, so probe sticking out, I like 🙂. Still have to test it fully 😁👍.
    Anyway great video dude 😁👍

      Most people have no need for a 150-500$ multimeter ..it just doesn't make sense. Most CHEAP-O multimeters can do everything the big boys can..sometimes alot more..the biggest caveat is input protection. Which is usually lacking on the CHEAP-O MULTIMETERS. That being said, unless you're planning to do measurements on a high powered mains, you don't need the extra robustness.

    Would have been a great cheap-o, had it had slightly better functionality. It seems they made too many compromises in that aspect to have good build quality and stay within a cheap-o budget. It’s just difficult to find a use for a meter with slow resistance and continuity modes, inability to test LEDs, low capacitance range, lack of live and NCV mode and lack of true RMS all in the same time.
