Oscilloscopio digitale a doppio canale SCO2 con velocità di campionamento 50M e banda analogica di 10 MHz. Un tasto AUTO anti-bruciatura
US$40.99 US$69.99

D: So how does this measure high voltage and 6 A of current. Is there a special cable needed that is not supplied. The Illustration provides no indication.

Domandata da artmezs il 2023-08-24 09:34:44

The seller To measure the current, you can connect it from the two metal heads in front of the oscilloscope, and the current direction is from IN to OUT output. The principle is the same as that of a multimeter to measure current, similar to a resistor, and it can be directly connected to the circuit in series. How to enter the current waveform interface, press the MENU button to exit to the main menu interface, switch to the current waveform mode by + or -, and press OK to enter.

I really like these arrays. They're so useful for a variety of projects, and the price is great.

I wish they would have stated how small your feet have to be to "fit" into this. I have a US size 12 foot and this is so very painful to use -- like a foot torture instead of foot therapy. I'm not going to spend my money to ship it back to China with a risk that it will "never show up". I will just write this off as a poor investment and yet another instance of China not being up to international standards of open disclosure, warranty, and assurance that Chinese products are meant for a world market.

I don't understand why this doesn't want to register power. I plugged it into my phone that was running at 0.45A with a regular cable, so about 2.5 W, but the display was blank and occasionally registered 1 or 2 W. I tried it on an 0.25 A LED load and it showed a 1 but it's so small and dim that it's too hard to see. The display never looks as clear and vivid as the "simulated" illustration! Also, this blocks power negotiation of my Gen 3, 10 inch Fire Tablet, which only draws 0.45A with this cable versus 1.42A on a "plain" USB-C cable (at 5V). When I use it with a PD tool that forces the output to be 9, 12, or 20 V, it does show higher power loads almost correctly, but still low compared to my 0.2% accurate multimeter. I didn't bother complaining to the company I bought it from, since they did not design nor manufacture it, and it's too expensive to send back. This was an over-priced disappointment.

I could have rated this 4 stars, but I didn't. Why? Because it has several shortcomings. First, is that fact that the mouthpiece inhaler (haven't tried the mask, since I don't like any of them) fits much too loosely on the unit and comes off too easily, but a session only lasts about 5 minutes, so I can tolerate that long. Second, its difficult to disinfect this unit since the entire unit must be cleaned and you see the problem there, right -- it's not waterproof as can be seen by the exposed USB charging port. I'm afraid that after a while, the unit will fail. My cleaning regimen uses an alcohol spray after carefully rinsing out the reservoir and discharge port with water first. Third is a lessor issue: toward the end, the unit starts to drip water, which was unexpected to me at first, but then the inhalant is liquid. So far, I've used it about a dozen times and I haven't needed to charge it yet (and it still works). I hope that I will experience a good service life with this. I do prefer it over the loud and bulky version I was using that plugs in to AC power and uses a hose to gain access to the stream of inhalant. Time will tell. PS, it may not look it, but the top actually screws on in about 1/4 turn, just in case you try to just push it on and won't work. I also got this on sale at a lower price.

D: The included "manual" was in Chinese only, so I don't really know what the included syringe is needed for (fortunately, I saw a customer's picture that showed the flask's top removed for better access -- before, I tried to use the syringe to fill it, but that was crazy slow).

This was a little difficult to put together, the pieces were well marked, the instructions were a bit small for my aging eyes, and my dexterity is not what it used to be. But, I finally got it put together. One small down side is that the upright length adjustment only has three positions because they are holes through the support rod. And since they're blind, it's hard to adjust to find those holes. I have other stands that do a better engineering job of this allow arbitrary height adjustment that does not rely on "holes" in the support to set the height. But still, it was a good deal and arrived quickly. It appears study enough but has a small surface area (which is what I wanted!). Wheels move well. Table has a slight tilt, so don't use for things that will "roll off" the top. Over-all, recommended.

What can I say about this panel and its amazing RGB LEDs other than WOW !!! The inventor should get Noble or other award. easy cascade up and down for bigger displays. Lots of software around to support it, even with a simple Arduino Uno. Good price too, but sadly, US shipping rates are too high now.

D: Why do you describe this as: "5V to 5V Isolation Chip" and later state input should be 12V /- 10% ? That's misleading and false ! Also, the link to the manual is dead and the one in the answers section (here) is Chinese only?

This order came quicker than most. I was lazy and delayed testing. But after I got a wireless USB driver for a "neopixel" string on Amazon, I decided to try it on this and another similar 8 x 32 part and both worked fine with that controller. This allowed me to check the functionality of these devices in a couple of minutes. A great time saver and it let me stay lazy and not lookup a way to test it (them) with an Arduino or similar device. However came up with the design idea is a genius.
