AstroAI Digital Multimeter, 6000 Counts TRMS, Auto Ranging and Manual, Measures Current, Voltage, Resistance, Continuity, Frequency; Tests Diodes,

I've recently gotten into using base station radios with all the attending coax and power supply boxes. I can wire a house start to finish, but dealing with voltage, ohms, watts on this micro level required that I up grade my multimeter. This brand and model kept coming up in the YT videos I was watching so I figured it must be a good one.I like the size of the screen and the overall dimensions of the instrument (7.5x3.5 inches). The unit has two strong magnets that anchor a short utility strap or can be used to attach to a metal electrical box with the magnets. Also incorporated is a pop out stand to be hands-free while using. I was already familiar with the Astron name from electronics and they have a good reputation in that field. I was surprised at how ... MoreI've recently gotten into using base station radios with all the attending coax and power supply boxes.

Read some off-road forums and this is the one most recommend for their vehicles. Helps in a cinch. The design and colors are nice if that matters to you. Works as fast as any other standard battery operated or car adapter powered inflator but is more compact and more pretty looking. It’s quality. I would keep it but found an uglier and larger inflator that has two cylinders which pumps twice as fast. Although I like this better for a lot of reasons, I need something that could inflate a whole tire from flat and top out the other 3 tires to ensure equilibrium without having to take a break. These are meant to run for approximately 10-15 mins at a time and then you’re supposed to let it cool down for ten minutes to prevent overheating. This works well but the other ... MoreRead some off-road forums and this is the one most recommend for their vehicles. Helps in a cinch. The design and colors are nice if that matters to you.

Its capacity will diminish over time. This will not.

I purchased this with my own money and as always, my review is my true and honest opinion.Honestly, I didn’t expect too much from this device given its price. Boy was I wrong! Testing it against a calibrated and certified oscilloscope, it was able to accurately measure the power draw of a microcontroller in the mA range to an accuracy of 0.4%. (pictures attached)I didn’t think much of the temp reading and don’t really have anything to test against, but I see these features as more of a gimmick than anything else.It’s a nice sturdy device and has a strap with a couple of magnets (that are not really strong enough to be of any use. Continuity testing is OK – not as fast as I would like but it gets the job done. Resistance testing fairly accurate as is voltage. I ... MoreI purchased this with my own money and as always, my review is my true and honest opinion.Honestly, I didn’t expect too much from this device given its price. Boy was I wrong!

I couldn’t get the Frequency reading to work but this might be due to my signal generator being on the fritz.The manual could do with a bit of work if you don’t know what you are doing but other than this, it is a nice little device that punches well above its price range

First of all watch video (google it) before charging the battery. Although it is easy to put together make sure it snaps in place. It will all make sense after receiving instructions. First thing to notice is that is is lightweight with or without the battery installed. Make sure you do a test run before you attempt to go outside to use the inflator as it is noisy. Although you may expect it to be noisy a test try inside will avoid scaring your pets, children and even yourself do death. The light shines very bright for night vision or for personal safety. Please have your PSI information handy (gathered from vehicle manual, inside vehicle door, gas tank or on tire and if possible put a label on battery charger or inflator to keep from having to worry about ... MoreFirst of all watch video (google it) before charging the battery.

Please have your PSI information handy (gathered from vehicle manual, inside vehicle door, gas tank or on tire and if possible put a label on battery charger or inflator to keep from having to worry about remembering PSI. The inflator works great and is fast as mentioned. I still keep the tire tube cap in my pocket for safe keeping. The inflator is easy to set the PSI and then just stand up as the inflator stands up on its own. It will automatically shut off when it reaches the PSI you programmed which is especially helpful for personal safety and if you have children in your vehicle. The case while a little flimsy will keep your inflator dust free and keep from accidental cracks. I believe the inflator can be easily used by anyone so a little family training would go a long way in case of an emergency. Some may think it pricey but you are paying for the 20V (quick inflate time) and the confidence that college students or grandparents can use it themselves without having to ask a stranger for help or wait for long periods of time stranded. I much prefer having this inflator and a separate car battery charger as two pieces of equipment so that they are not heavy and can easily fit in glove compartment if need be. Use with confidence after doing a trial run before you need to use it.

I will state outright that I am not really leveraging the ability of using the all functions to be super precise such as Fluke multi meters( but its also costs only a fraction of what a similar fluke does). i do a fair amount of electrical work and electronics troubleshooting. A quality multimeter is a mainstay tool in my line of work, so when I saw the price within my Budget i grabbed it.Overall, it seems to be very well made, and provides all of the testing / verification measurements that I utilize on a daily basis. I probably need to spend some time reading up on various scenarios that would make using the all feature more efficient or easier, but, for the time being, I continue to leverage the probes for all my readings.Thus far, I have had no issues with ... MoreI will state outright that I am not really leveraging the ability of using the all functions to be super precise such as Fluke multi meters( but its also costs only a fraction of what a similar fluke does). i do a fair amount of electrical work and electronics troubleshooting.

A comparable Fluke unit would cost close 5x as much, and, for semi-pro or the DIY space, there is no need to go all out. I think this is a great step-up option for someone that needs a little more than a traditional digital multimeter, but not yet ready to break the bank on a professional industrial Fluke meter.For ~$39 CDN (current price), it is hard to go wrong. If you need a step-up from a basic multimeter, this is definitely worth your consideration as it does Have 6000 true RMS.

There is no manual and not much out there regarding how to calibrate this thing, but i figured it out.You will need a soldering tip thermometer or a multimeter with temp mode and probe.I rested the iron in the cradle as normal, and stuck the probe down through the small holes on the top to the side and situation the probe under the tip of the iron.Press and hold the CAL button until the temp readout on the station shows the numbers of the temp separated with dots (eg 3.0.0)One the temp is stable on the multimeter, adjust the dial on the solder station to match the readout on the meter, the solder station will revert to 3.0.0 automatically, watch the temp readout on meter and wait for it to be as stable is it will get.Repeat until you get as little ... MoreThere is no manual and not much out there regarding how to calibrate this thing, but i figured it out.You will need a soldering tip thermometer or a multimeter with temp mode and probe.I rested the iron in the cradle as normal, and stuck the probe down through the small holes on the top to the side and situation the probe under the tip of the iron.Press and hold the CAL button until the temp readout on the station shows the numbers of the temp separated with dots (eg 3.0.0)One the temp is stable on the multimeter, adjust the dial on the solder station to match the readout on the meter, the solder station will revert to 3.0.0 automatically, watch the temp readout on meter and wait for it to be as stable is it will get.Repeat until you get as little fluctuation as possible.

For ages I've had one of those cheap multimeters, and I really fancied something a bit more capable - this did not disappoint. I got it, the Khanka Hard Case, and the separate test leads kit all together as a gift to myself. While I might have loved to own Fluke, this one does what I need without breaking the bank!It comes with enough stuff to be immediately very good, though I prefer the test leads from the separate kit - the stock ones are fine and still come with removable tip shrouds (so you don't accidentally short between component legs so easily).The display is nice and big, and there's no problem with viewing angle. The backlight is electroluminescent or similar, so it's a good uniform blue to read off.The built-in stand is nice and steady, but it can ... MoreFor ages I've had one of those cheap multimeters, and I really fancied something a bit more capable - this did not disappoint.

The backlight is electroluminescent or similar, so it's a good uniform blue to read off.The built-in stand is nice and steady, but it can jam sometimes when folding back in. There's an integrated magnetic strap too, which I've not had to use yet but which is very good at picking up steel grinding dust from the workbench.While the test leads are all properly shrouded for safety, you can also plug in regular 4mm banana leads if you're doing a hookup on a bench (the separate test leads kit comes with spring clip leads with stacking banana connectors, which can be really handy for certain setups).One feature I bought this specifically for is that the current measurement ranges all use separate connectors - so there's never a situation where the voltage test ports are shorted together. So long as you're methodical and always return your leads to the main input, you're unlikely to accidentally blow up fuses (or equipment). There are two separate current connections and both are separately fused; there is no unfused range. The current shunts are somewhere around 100mΩ (A connector), 1Ω (mA setting) 100Ω (µA setting).

I own a pancake air compressor & I dreaded getting it out. I forgot to check my small utility trailers air in my tires, when I got home, they were 50% lower than they should have been. It was a slow trip home with a full load of dirt.I saw the one on the TV a long time ago & told myself I'd never use one. Wrong.When I saw it again, I began researching. I complained to my parents about dragging out the air compressor, they never shared they owned one of a different brand.Moving on, my wheelbarrow tires needed air & even though their smaller tyers, it works great & makes my life easier. I was having issues finding a good tire size flat free but too expensive. No more a problem.Not too heavy with the battery in, if feels like a cordless drill weight.This is a ... MoreI own a pancake air compressor & I dreaded getting it out.

I am not a "handy" person, and have never tried to inflate my car tires before. I live in a cold climate and every winter the TPMS light comes on when the pressure drops due to cold temperature. I used to try to find a tire store or gas station and get help to inflate the tires. But now I don't have to do that any more. When my TPMS light came on I used this inflator and it worked exactly as advertised, and my TPMS light went off indicating it did inflate my tires sufficiently. I removed the valve stem cap and easily inserted it into the valve stem and used the lever to seal it. The display showed the low pressure, it inflated and automatically turned off when it reached the target pressure. The light for extra illumination was helpful. I highly recommend this ... MoreI am not a "handy" person, and have never tried to inflate my car tires before.
