True RMS multimeter - RM409B (Bside zt-x review)

Ғылым және технология

Unboxing and reviewing the Richmeter RM409B (Bside ZT-X).
Trying to analyze the best digital multimeters under 50 $ in 2020, I came up with this review about this most accessible true RMS device.
During the video i discuss the topics related to the functions of the multimeter and I come to the following conclusions which I also displayed on the screen:
Good things:
- True RMS
- Fancy display / design
- Lots of functions
- Multiple screen readings
- Auto scaling
- Good buzzer sound
- Good diode tester
Not so good:
- Short leads
- Unuseful sticker for protection
- Slow data processing
- Thin probe wires
Of course, the voltage comparison is done using my Fluke 87V meter.

    Great review. You took the time to test all of the main features. It helped me to make my decision on wich multimeter to buy. Greetings from Mexico.

    Thanks. I was curious about the low range limit on the duty cycle (or Hz/%) testing myself. I have a meter here to do those kinds of tests with, but it's limited to being greater than 7 volts to read accurately. PS: The face @11:44 was priceless 😋

    I have several FLUKE equipment, I think this multimeter is very good for quick measurements. It works great, I buy one of them and do my own tests.

    Hi. Is this better than the Fluke 101, Fluke's budget multimeter (but I think it doesn't have a temperature probe)? Is this multimeter good enough to measure the capacitance of the smallest SMD capacitors in the iPhone and retro video game consoles? Thank you. God bless.

    Salut. De la primele cuvinte si de cum te-am vazut mi-am dat seama ca esti de-al nostru :). Si moldovean. Super! Cautam un review la multimetru ala si-am dat peste al tau. Si eu sunt inginer HW. Cum ai ajuns in Papua Noua Guinee? :) Bafta in ceea ce faci.

    Did anyone tested this model to see how fast it can respond to shortage/ continuity check on a board?

    Regarding the comparison between the Fluke and these other multimeters, somebody commented on a different video of mine that the Fluke cannot be compared with them because it’s a different something. I think it’s worth posting the discussion here and my reply to this issue since there might be more people out there interested in this topic. CB: “Fluke has bargraph that's fast mastech don't. fluke has conductance function mastech don't. fluke's minmax capture mode is super fast mastech just average. fluke's build quality is far far superior than mastech. fluke's test lead wires are silicone mastech melts when accidentally touched by soldering iron. fluke is accurate even when measuring non sinusoidals mastech just good with sinusoidals. fluke's display is clearer than mastech. so on so on and so forth” FunElectronicsToday: Now Fluke is meant to be an industrial $450 meter and the Mastech is only 10% of the price and intended to be an amateur one. I for once, bought myself a Fluke because I wanted a meter I could trust and a guaranteed measurement. Many times I make projects for different customers and I have to create official documents and test reports with added measurements and numbers. I couldn't do official numbers using a DT-182 multimeter. How could I show a report like that to the customer and who would believe me? As the years passed by and I grew up being a HW designer I saw from experience that measuring something with a cheap multimeter gives me at least 5% chances of having a big human or device error I usually take for granted as being a good measurement. It could be either the fact that I am rushing or the fact that the probes are not making good contact and the display is not fast enough to tell me that, but if I measure 100 times there is a good chance 5 times I get the wrong numbers. Combine that with the limitations of the meter, like resolution, speed, range, etc and you end up having a limited device that can hinder a good measurement or cause errors. For amateur use and everyday repairs this is good enough. But for long term HW design this was not good enough for me. If I am thinking of embedding a new component in my design and I go ahead and measure it's current, voltage dropout or resistance, compare that with the datasheet and then calculate everything for making a robust design that needs to last for 10 years in harsh conditions, I need to be sure. It doesn't help me if I only trust my meter 95%. This comparison video was made to provide a good accurate overview of the meter so anyone can see its limitations and decide for themselves if this device suits their needs. There is another side of it I could never say in the video back then when I shot it. There was a time in my pioneering years when I was content with using cheap multimeters. After almost 20+ years of practicing my profession I started to want more and seek more professional tools. Once I started using Fluke, Agilent, Tektronix and other industrial tools at work, I realized that nothing would be the same if I go back to my old meters in my shop at home. It's like being a F1 pilot and going back home to your simple Ford Fiesta. The profession skills growth asks for an automatic tool upgrade and boosting up the tools level works out more skills for you in the future. This is how the normal growth curve and profession developing cycle works in everyone of us. I guess... What do you guys say about this? If you hear somebody claiming they work for NASA or Tesla motors and they argue with you that DT-182 is just as good as Fluke and Hantek like Agilent and that it doesn't mater it they do spacecraft design using DT-182, what would you say about them? You would say that they are either lying they work for these companies or they got some mental disease recently. Na?
