You're probably right, but I've never seen a process calibrator before. I'm not familiar with them. I was expecting something that generates waveforms including a sine wave up to many many MHz. A signal generator is sort of a wrong name for it...
@@DiodeGoneWild a lot of industrial equipment used to be (still is?) controlled by sensing a current from 4-20mA. It has two advantages: 0mA means there is something wrong in the control loop, not just a value is 0%; 4mA corresponds to 0%. And using current means you can't get a low reading from a voltage drop in a long control wire. So these are built to test / calibrate machines running off that system, and anything related to it.

4 to 20 MA is the typical output of various types of industrial sensors, pressure, flow rate, etc. Current is used instead of voltage because electrical interference usually appears as a voltage. Resistance would also be problematic.
I just wanted to thank you for creating such informative and valuable content on your TH-cam channel. I stumbled upon your videos a few months ago, and since then, I've learned so much from you. Your videos are always well-researched and presented in a clear and engaging manner. Your dedication to your craft and willingness to share your knowledge with others is truly inspiring. I appreciate the effort you put into each video and the passion you have for your subject matter. Your expertise has helped me gain a deeper understanding of the topics you cover, and I have incorporated many of your tips and advice into my own work. Thank you again for all the hard work you put into your videos. I look forward to watching more of your content in the future.
I'm impressed by all the engineering that goes into these fnirsi products, but I already have a fancy Rigol desktop function generator that never gets used...
Almost but not quite exactly what I want! I work on building automation (primarily HVAC control systems) and that would be useful for troubleshooting, but is missing the ability to read / simulate 10k thermistor sensors which is the bulk of what we use. I once made a PCB with a rotary switch, voltage and current regulators, and some resistors to produce a stepped 1-10V / 4-20mA output for testing actuators, has come in handy on occasion but I never put it in a case so it's usually in need of repair by the time I go to use it again... 😅
Makes sense to convert a voltage etc into a 4 to 20mA current to mitigate voltage drop on cable runs and obviously you can't have 0 to 20mA because a disconnected sensor and a sensor reading 0mA are the same thing 😅
Or 'auto' as most sensors interface through simulation of V or ~ example a MAF air flow or MAP pressure & of course air & water temp, so to test or simulation of a possible faulty sensor that is being fed to a secondary CPU oft one sensor can change many other outputs etc.
It is invaluable when debugging MCU firmware for connecting to sensors and actuators. Instead of trying to affect the sensor or see how actuator reacts, just connect this and keep debugging. Also, because of form factor widely used in the field to troubleshoot various industrial equipment (as others pointed out).
Yeahp, I work at a power plant and this is a Process Calibrator similar, but not like some I use as this one comes with oscilloscope feature....!!!! No doubt that miniaturization of electronics has come a long way. Very nice device and great video.
Factory maintenance guy might carry this around so he can jump on problems quickly. Lots of features. Maybe not so useful in countries without big factories.
Na začiatku som aj ja bol zmätený a nevedel som presne o čo ide, ale po tvojom vysvetlení a ukážke som pochopil a súhlasím s tebou že názov "signálny generátor" nevystihuje veľmi dobre účel tohto zariadenia. Ale v priemysle nájde tento prístroj veľmi dobré využitie.
According to the manual it can be controlled under MODBUS Slave mode and at the end of the manual there are tables of MODBUS functions (check 2:57 and 5:25 on video). But, the manual does not describe how to connect the wiring. Does anyone know how to communicate and control this device using MODBUS (RS485) ?
On the 16:03 mark there are 2 unpopulated connectors. The one with TxD RxD is a serial port. Not sure about the second one, it says CLK and DIO which hints at I2C. Can you try connecting the serial one and see if there is anything? Boot console perhaps?
This seems like an interesting device to troubleshoot industrial equipment using 24V or 4-20mA senors, but those would usually use M8/M12 connectors, and I don't see any adapter included? You can't really do much with just alligator clips.
Great review as always and an interesting bit of kit, very 'Niche' but I bet if you need one I'm sure you would be very happy....may the salt be with you...cheers.
Danyk can You tell how to calculate bulk capacitor capacitance in smps? (tl494) For example output would be 54V 5A and 80% efficiency (for me it looks like half bridge. It is btw ebike charger). I watched your video about linear powe supply and filtering capacitors, and would love to hear your opinion on smps in this topic. In linear power supply i made your circuit and i could observe different capacitances on oscilloscope but i can't observe it on mains voltage because i got no equipment to do it safely. And of course i could simply change faulty cap for other with same rating but im curious how to select proper one for task.
Dear sir i saw your metal detector project.Your work was extraordinary.If you modulate transmitter transistors base bias(on/off=1khz) with(lm555)square wave.Then metal detector may be works on static mode also.Please try and make a video Thank you sir.
That oscilloscope scope can’t trigger correctly as the ADC’s are not what as they are claimed. Plus is 50mV/div being the lowest. Won’t be good for troubleshooting power supply repairs and etc, like ripple and transients that he typically does on his channel. Most modern oscilloscopes even the cheap ones do 2mV/div and most now 1mV/div is common. In other words the 1014d is junk and doesn’t meet it’s specification as they lied pretty much and trigger doesn’t work correctly as tested one and was barely usable to downright bad.
It is very strange this coming from cheap brand like Fnirsi. Process calibrator is of no use to most hobbyists and industrial users are obviously going for much more trusted (and expensive) brands.
I thought the same thing why would they bother to design, produce and market a process calibrator? It not of any use to hobbyists and for production use most if not all go with a trusted well established brand that they have contacts with. It a oddball decision and device for sure.
Hi,are you interested in trying a thermal camera to locate electrical connections and inspect energy efficiency in your projects? We can send you a free sample to review
@@DiodeGoneWild Ah. See, that's what happens I didn't read the manual I don't have 🙂. So now I'll look at the link to the beast, and probably get one. Would be handy as a non certified Yes/No bit of test gear at work. Cheers Pete' New Zealand.
I want one just to find something to use it for 😂😂😂 cud it be used to test circuits like boost converters motor controlers and such 👍 I don't own a scope so it's a guesstimate 😂
It is usually called a process calibrator and you can get it from many brands.

@@DiodeGoneWild Basically it's a precision voltage reference and current source.
this id for the calibration of field instruments basically for instrumentation

An instrument from a different universe!
It is for Air Conditioning systems. It needs to test and or simulate sensors used with A/C systems for testing a whatnot.

We need to see what's in that charger. Is it DODGEY?
I have it from some time and can tell that is amazing tool for troubleshoot and calibrate.

16:03 is the end of the video. 15:13 I see the connection points.
Came here for your cat but the toy is interesting too!
How are they simulating the resistance? Maybe a low value resistor and Chopper/Pwm low pass etc ?
This seems like an interesting device to troubleshoot industrial equipment using 24V or 4-20mA senors, but those would usually use M8/M12 connectors, and I don't see any adapter included? You can't really do much with just alligator clips.
Wow! I will buy 10 of them!
Check out LB02a (less functionality but better accuracy) or MR9270S+ (pricier but better) if you're serious!
@@scottshaw1310 🤣
Funny thing, I am looking to get a signal/function generator.
Sad that even old ones are expensive

Nice gadget, if not a little above my comprehension as for uses.
Can I use it to find data and clock signal of mobile phone cpu?
It needs a knob, or a thumb wheel.
Yeah. The user interface seems pretty painful. Which is pretty much the most important part of a device like this.
👍very complicated. But still cool

Hello. Definitely! :) contact me at danyk@centrum.cz
I guess you could do the same with a Raspberry Pi Pico. Maybe build one and compare it.
Sure, if you're looking for a big programming and electronics project...
@@Basement-Science there‘s someone who did a thing like this I think.
Niceeee :)
Take the USB power supply apart.
Looks dodgy to me
I get crazy every time you poke some smd components with metal screwdriver without removing the battery.
Only 12 volts open loop for 4-20mA. Normally 24 in the real world. Otherwise not a bad bit of kit.
It can be set to 24V too.
