    Great video, same as video #1.
    Bluetooth: Now in 2018 I see that FLIR does have bluetooth with the DM93, and they said it is free. Allows for remote measurements, better safety. Apple & Android apps, but no software available for a computer, unfortunately. DM92 does not have the bluetooth option so must review the logs from the meter.
    Mains test: I know that someone posted a video on the Fluke 117 and measured 240VAC, and switched through the entire range of positions of the selector switch, and back - no damage. Nice to see this similar test @ 120VAC on this meter, and that it held up without damage or blowing a fuse. I believe this says a lot about the quality of the meter.
    Battery Testing: so my new EBL AAA high capacity NiMH batteries won't suffice @ 7.2V fully charged. Need alkaline or lithium. If wanting to use the flashlight, the alkalines will be dead too soon. I have not found a good lithium rechargeable yet, I think still a bit dangerous with the charging.
    Weather resistant: now has an IP54 rating, somewhat water resistant. Good.
    Adding the magnetic hanger, type K t/c, case, usually all costs extra, but still quite a bit less than the Fluke 87V.

    I LOVE MINE!! I am very glad I got one.
    My fluke 87 V is up for sale. UGH.
    Thanks Martin for the GREAT vids on this unit. FLIR kicks butt!

    FLIR has a free app in the Google Play store. I dunno how long it's been there, but it's there now. Might want to give it a look?

    Now you have multimeters of all colors but blue on the bench :-) (I like the green isotech color - never saw a green before).
    A nice review and looks like really good build quality, but I have to agree with the other comments. They should have used at least AA accus and used them more efficcently. It's really a brick so they could easily fit in. And it is way too expensive (all they are) even for a professional multimeter. Nothing really fancy what could explain such a high price (even with bluetooth and datalogging it shouldn't be more than 200). But I like that Flir reacted on the problems you found in the past.

    Good review, the meter is very interesting to me, especially the data logging feature and the bluetooth feature (hopefully in future). Due to the fact that it would only be a secondary meter for me, I'm very picky about several things such as battery consumption and so on. (good that it doesn't chew on the batteries when it's turned off) I hope that Flir will give you some feedback about the bluetooth connectivity/android app.

  • @matutolaYT

    Agilent have bluetooth connectivity with android and PC, the software is free and available at Play Store.
    The hardware required is the Agilent U1177A, and I made more then 20meters with it and my android phone.

  • @willyrivero470

    I think AAA batteries is actually a plus considering that they are less pricy and there's not much of a big deal considering the meter doesn't consume any current while off.

  • @erickmoraes9205
    @erickmoraes9205 10 лет назад

    Please forgive me if I'm wrong, but I believe that Agilent U1272A does have data logging capability.

    Martin, I get the sense that you want to improve your knowledge so you can stub your toes with the best of them. I'd suggest a couple of ways you could scoop Dave Jones. One, you could do a rough bill of materials in a review like this one. Inquire prices on key components and estimate the rest. That would be potent enabling knowledge for the viewer. Something that makes them feel they have been enlightened. Empowered. Hooked like little junkies so they have to come back.
    Another thing is to expose a meter like this to extreme voltage, say 12000V from a large transformer station, to see just how much it explodes and see just how real CAT rating design concerns are. As opposed to intuiting it. You might also try applying high current 1000V (very large cap) directly to the fuse while inside the case as a test of what would happen if something in the meter failed significantly while testing rated voltage and the fuse was the last defense. It might well reveal that 10$ meters have plenty of safety in the case. And maybe that cheap glass fuses do fine. I suspect it might also reveal that the leads are far more dangerous in a high voltage situation than parts exploding out through the case.
    You want to do stuff that really grabs the attention of the nerds who are watching. Something to make your channel stand out. Something with teeth.

      AFAIK, they changed the formula of the Bromine flame retardant several years ago. The old brominated retardants are what caused the yellowing. I stand to be corrected, though.

    The power consumption is quite bad. Not only that but they used 6 AA batteries and probably NiMH rechargeable will not work because of the low bat warning at 7V that is only 1.16V/cell almost nominal for rechargeable batteries it should have worked down to at least 6V.
    The should have used lithium rechargeable batteries especially considering the high power consumption of this.

    Next time put the screws in small boxes, so you will not loose anything.
    You may use multiple boxes, each containing screws from a specific section. I took this advise from "mikeselectricstuff" :P.
    Nice video, Thanks!

    Using alkaline one time use batteries is consistent with the general 1980s technology level. Why not use a single 18650 laptop lithium cell. They are dirt cheap (

  • @SkazaTV
    @SkazaTV 10 лет назад +3

    ''Just under 7Volts-thats perfect.'' Why?
    You have 9volts and it only uses 2V from all power avillible. Thats horrible.

    • @Brant92M
      @Brant92M 10 лет назад +4

      Generally speaking, you've used 90% of all power available to an AA/AAA cell at ~.9V. Beyond that point you start risking physical damage to the cell, and damage to an alkaline cell is NOT something you want happening in your $400 meter. Battery acid is very corrosive and can easily ruin the whole thing.
      Alkaline cells' capacity actually depends on their discharge rate. Here is a datasheet for the AAA cells FLIR provided that has some nice discharge graphs: data.energizer.com/PDFs/E92.pdf
      The reason that the cutoff voltage is set to 7V is because at the 12mA idle current, the meter is drawing 80mW. If you look at the datasheet I linked, they have a graph of 100mW discharge rate. It drops off _dramatically_ after 1v. In fact, at 7V, you've got an average of 1.16V per cell, which is in the safe sort of operating range.
      Voltage alone isn't a meaningful measure of a battery's capacity. "9 volts" doesn't mean anything at all. A 9V pack of AAA cells will give you maybe 1.2Ah on a good day, but a 9V pack of Lithium cells can go upwards of 3 or 4Ah easy.
      Likewise voltage doesn't necessarily measure how much capacity is still in a battery. Voltage verses capacity is _not_ a straight line, and it depends heavily on what your discharge rate is.
      So no, 7V is not horrible, it is, in fact, perfect.

      I agree 100% It´s an old design. Fluke has the same problem design from the 80s ´. They would put 16850 batteries or other high energy rechargable type.

    Well this was an annoying experience watching this video. First 10 second splash screen which serves no purpose. I go to couch get comfortable and a video ad starts at 30 seconds (instead of 0 seconds like normal), so I have to get up to skip over it, then the tag annotation with the number of subscribers stayed up for the entire video. The content itself was good though.
    I think it's a nice looking and well built meter. As pointed out the battery design is a huge miss. Knowing the Fluke draws power when off though is a deal breaker for me though. I still like the old Blue Agilent OLED DMM's the best and only for their sex appeal. When a meter looks that good I am willing to overlook a lot, lol. I did hate the new versions orange case, but it's starting to grow on me.
    My dream meter would be one with the gang switches on the side like they had around 1985-95. An OLED display. Lime green case. Bluetooth. Fluke 87 accuracy and build quality. I would pay $800 for that meter if someone made it.
