3 in 1 Handheld Oscilloscope Multimeter Professional Oscilloscope Multimeter with High Sampling Automatic Waveform Capture Function

I got this multimeter to replace my trusty old fluke multimeter that I accidentally broke. I knew I wanted a multimeter that had auto ranging as well as pretty much all the basic capabilities and a multimeter should have But the thing that made me want this one was the fact that it has an oscilloscope feature which is incredibly useful when checking PWM signals and sine wave forms. The meter itself is light but doesn’t feel super cheap like some that I have owned in the past that being said this does not have a case around it so you should still be careful with it but you don’t have to worry about it being broken just by holding it like some other brands. The color OLED display is very nice and can be seen even in some brighter areas although it can be hard to see in direct sunlight as anything with a backlit screen can be. Overall it’s definitely worth the price is even the most basic fluke multimeter sells for around $100-$150 in those don’t have anywhere near the capabilities at this test

This is the best oscilloscope I have owned so far. You can measure ac voltage inside your residential home and as well you can know what frequency is 120V etc, this oscilloscope I bought it for setting gains of any Car Audio Amplifier it really works accurate you can change the time and range when using 40Hz and 1kHz test tones. The product looks similar to the TPi 440 Oscilloscope. This oscilloscope works well and I plan to keep it forever.

I only had this a couple of days, but I have tried all the functions except for current measurement. Everything works as expected. Voltage, resistance, and capacitance measurements all seemed to be accurate when compared to an independent source. Purchaser needs to be aware that the oscilloscope has a very limited bandwidth (1MHz). So you should only use it for low frequency measurements. I used a signal generator up to 100KHz and it seem to work well, but there was a little attenuation in the output. Based on the battery indicator, it seems to be a bit power hungry, so I suspect the battery life will not be great.

I do a lot of solar energy work. This 'Scope/DMM covers a lot of ground. Since it can go to 700vac, I can test waveforms straight off the inverters.This test in the photo was for a portable power unit that brags about being a modified sine wave. In reality, it is a PWM square wave with no finesse at all. A true modified sine wave has another step between zero and full + or - to more closely mimic a sine wave. The output of this unit is demonstrated to be 'dirty power' as an AC source.This small package is super convenient for my type of field work and the price is right. You probably need one too.

Accuracy Compares well with Fluke DVM. Boots up quickly. Easy on Batteries. The Controls ( if You don't use the Scope portion much ) can be a bit of a challenge, but by referring back to the Manual ( or in my case I made a cheat-card of functions I use ) makes it pretty easy. I can pretty much ALWAYS get to see what I want, up to 100kHz or so, which is all I need most of the time. GOOD VALUE !!!!

I needed to correctly set gain on a couple car amplifiers and didn’t want to spend over $100 for an electronic device that would be used at most a few times a year. On the other hand, I didn’t want to cheap out and risk damaging my carefully planned and installed equipment…or my truck.After seeing a couple DIY Audio Guy vids with this o-scope, it seemed like a flexible, reasonably easy-to-use device. Using Kicker’s -5dB test tone, and without reading instructions, I was able to set the gain on a 700W monoblock amp with a little bit of headroom left as a safety margin. Will do the same on a 75x4 class AB amp in a couple months. As a side note, setting gain with a multimeter can be quite inaccurate unless you have dyno sheet for that exact amp. O-scope is the best method.If you absolutely need auto-ranging and higher resolution, this may not be the correct tool but if your application is similar to mine, this is a great value.

I could of got a fluke for price like this, but decided to try my luck with it anyway. I wanted a quick and dirty way to visually see any noise on DC connections. Just something to grab and go in the field. It's does do that. But it has a few quirks. It has this auto-ranging feature 4-40-400 volts. Which sometimes doesn't work. It will show OL. and take a second to figure things out. but sometimes it just beeps saying OL even if the voltage isn't really all that high. Setting the range manually also seemed to not work and still said OL. releasing and retesting seems to clear it up. but this is not good. But where else are you going to get a portable oscilloscope.So some things. It's cool to see a big color display. but not cool to try to read it in sunlight. that's a biggie for me.It does have a beeping continuity function. but you have to push the function buttons to get it into that mode.Resistance/capacitance/diode functions work. haven't tried current. but I usually infer that with my own external shunt. I don't rely on the shunt inside the meter itself because you often blow the fuse (true with any meter)It DOES turn itself off if you leave it on idle. it also beeps at you before it does. which is nice.So if you just want a cheap portable oscilloscope.And do things on a bench and have time to fiddle with it. Has at least a good set of leads. Then I guess it's ok for that.But if you rely on a meter in the field in all conditions. need fast display readout. This ain't it.

Oscilloscope function works well. Handy for checking canbus function along with speed sensors recommend getting backprobe kit to go with this unit.
