AstroAI Digital Multimeter TRMS 6000 Counts Volt Meter Ohmmeter Auto-Ranging Tester; Accurately Measures Voltage Current Resistance Diodes Continuity Duty-Cycle Capacitance Temperature for Automotive

I occasionally purchase low-cost test equipment, conduct a quick review, and then post the results to my w3afc. com's website. This is for the benefit of HAM Radio operators who are on a fixed income and want to repair their own equipment. In a few weeks, I'll post a complete review with photos. This review is aimed at the average homeowner or DIY enthusiast looking for a low-cost, high-quality product. a meter that is highlighted I put this meter up against a much more expensive Amprobe AM-2000 meter as a comparison. 570 PROS: br>br>

- The back of the magnet has two plastic-coated magnets that are extremely useful. I can stick it to the face of one of my vintage HAM radios and it will stay put while I'm testing.
- It features a spacious, user-friendly design. look at the screen
- The RMS readings for both DC and AC are well within the claimed ranges. Spot- on the contrary. br>- The readings of resistance, DC current, and diode forward voltage are all correct. The Duty Cycle and Temperature functions have not been tested.
- For a meter at this price point, the build quality is above average.
- This meter can read voltages up to 1,000VDC (CAT II) and 750VAC, according to AstroAI, but they don't emphasize it. I have yet to use it to measure the 900VDC plate voltage on one of my Swan 700CX tube transceivers because I want to put it to good use before risking blowing it up. In addition, I intend to use it primarily for circuit testing in automobiles and solid-state lighting. HAM radios licensed by the state When I tested the Swan plate voltage (at rest, no modulation) on a UEI 384 that claimed a maximum DC voltage rating of 1000 volts, the UEI blew up - to say the least. I found a used one for $20 on the internet and gave it another shot. That meter, too, went off the rails. As a result, I usually take the voltage ratings on these low-cost meters with a grain of salt. br>- This meter, according to the manufacturer, can measure capacitance up to 600 micro-volts. farads (uF) are a unit of measurement for the number of farads in The one I'm testing, on the other hand, has accurately measured up to 2200uF. Maybe they meant 600uF within the accuracy range. br>br>NOTE: if you're looking for a unique way to express yourself, this is the place to be I'VE UPDATED MY RATING to reflect the fact that this meter has a 60,000 uF rating. Right now, the highest value I have is 20,000, and this meter reads it with the same level of accuracy as my much more expensive Amprobe AM-2000. My CEM DT-570, as well as my 570 9935 LCR. CONS: br>br>

- That magnet I mentioned earlier can pick up nuts, staples, pins, and other small objects, so it serves a dual purpose. - a sword with a cutting edge. br>- a sword with a cutting edge The claimed upper limit of 60MHz for the frequency counter is actually 16MHz. When engineering told marketing that it would read to 16MHz, marketing misunderstood and assumed they said 60. Furthermore, the voltage needed to obtain a reading is quite high, nearly 5V P-V. The Amprobe AM- is a device that detects the presence of ammonia The 570, on the other hand, reads accurately up to 43MHz and only requires a little more than 1V P-cell voltage. P for a great read. Of course, it costs around $110, which is nearly four times the price of the AstroAI WH5000A. Note: My Amprobe manual claims to be able to read to 60 MHz as well. Based on the fact that these are 6000-plus people, I suspect this is just a theoretical figure. Count how many meters there are (5999, to be exact).
- The transistor hFE (current gain) test function operates at only 1 volts and a very low current of around 1 mA, indicating that it measures about half of a device's gain under typical conditions. And, for some reason, the multi-player mode isn't working. The function test adapter is arranged in a C-shaped pattern. B should be replaced with E. E, by establishing a TO-DO list for testing. It's a pain to deal with 220 different devices. So, if you're looking for a transistor tester, this isn't the one for you. br>br>As I previously stated, I will eventually post a comprehensive review on my website. This is an excellent choice for a hobbyist or DIYer, and the price is unbeatable. I would invest a little more for HAM Radio work. BTW, I'm not bothered by the beeping at all. br>br>NOTE: if you're looking for a unique way to express yourself, this is the place to be A Tektronix Calibration Fixture was used to provide DC voltages. The AC voltage was supplied by a regulated AC supply set to 115 volts. 00 VAC. Because the AC supply does not have BNC connectors like my Tek DC supply, I tested it separately from the Amprobe meter. The AstroAI picked up a small amount of AC when the probes were removed, which was most likely from my fluorescent lighting. br>br>NOTE 2: If you're looking for a unique way to express yourself, try using the words "innovative The frequency 14 is being measured by the meter in the photo of it testing something on the underside of a radio. 175 MHz from a Kenwood TS-2000 signal unit Transceiver for amateur radio (HAM) model 930S. The meter is located near the output terminal on the board. It reads the signal, but in order to get a reading, the board's gain (carrier level) must be set to 10. By comparison, the Amprobe can read the signal at a carrier level of 4, and an old Beckman Industrial DM27XT can read it at a carrier level of 2. The AstroAI and the Amprobe are measuring the same 2200uF, 35V electrolytic capacitor in the two new photos of the meters measuring its value. br>br>I received a call from the manufacturer about my 3-year-old son. a rating of five stars When compared to other meters in the $30-$50 range, this one is a bargain. This would be a 4 or even a 5 star rating if it was in the $50 range. However, I would only recommend the Amprobe AM- to a friend. 570 4 stars, so I'll give this 3 stars for consistency's sake. br>br>By the way, I've got the thermocouple connected right now in my HAM shack, and it's measuring the ambient temperature. As the heat comes on and off, the temperature fluctuates between 71 and 73 degrees, which is just right. After a few minutes of putting the end under my tongue, it reached a temperature of 95 degrees Fahrenheit. So it isn't laboratory-quality, but it isn't bad either.

0Ω. This meter does not do so, and it also does not stay on a value. I tried using the "relative" button, but when I touch the leads together, I still get erratic values that don't stay on a single value or show zero. There is no resistance. I'll be returning this meter, and I'm hoping that this review will save someone else from having to deal with this piece of garbage.

It's quite large, and it has an odd blue hue to it. Backlight is dim, but the display is large and easy to read. Accuracy and update speed are surprisingly good, as is repeatability, but long-range reliability is still unknown. The magnet hanger is a good idea, but it would be more useful if it had a stronger magnet. After a thorough cleaning of the tips with fine steel wool and alcohol, the leads are surprisingly good. The meter's overall accuracy appears to be very good, and it has an acceptable, if not overly loud, but audible continuity tester, and it zeros out well when the leads are shorted. The 9v battery and two small ceramic appearing fuses are accessible after removing the battery cover on both ranges. The case screws do not have metal inserts, but this is a budget meter, so it is not an issue at this price. My biggest complaint is that, while I am glad it has a backlight, it has an odd appearance - It only stays on for a few seconds, and when you turn it on, the numbers have a strange slightly washed-out effect; don't get me wrong, the display is still readable; it's just not as vibrant and crisp as others - Someone else might not notice or care, and as a budget meter, it isn't a big deal. I'm not dissatisfied because I knew what to expect when I went in; the meter functions well and has a lot of features - However, you can get a Fluke 101 pocket meter for under $50 right now, and while it doesn't have as much functionality, it does have the reliable Fluke reliability that has been demonstrated in tests on YouTube - It all depends on the type of meter you're looking for - Overall, this meter is a good buy, but shop around for other options in this price range; there are some good deals to be found elsewhere. It's a fair question to wonder why I didn't purchase the Fluke 101. One reason is that this meter has a lot more features, and two, I already own a Fluke 17B, but the main reason was pure curiosity based on reviews. I saw good reviews and a large display with a lot of functionality for a reasonable price, and I'm a meter collector, so I bit - This is the type of meter you can throw in a toolbox or throw in the truck and be good to go for very little money. Just find a cheap carry bag to fit online and you're good to go. There isn't much to lose if someone "borrows" from you. a Fluke or other reasonably priced meter Even with the minor flaws I mentioned, it's a good buy and you couldn't do much worse for the money. There's a lot to see in this price range, so take a look, but be cautious because there's a lot of junk out there, so read and watch any available YT video reviews on any meters you're considering.
