Is it possible to use the signal generator and oscilloscope at the same time with this device? On the one hand, should we apply the frequency device with the signal generator and on the other hand, see the result simultaneously with the oscilloscope?!

You’ve got to respect the Keithley 614 Electrometer which is still a relevant instrument today. The 614 debuted in 1981! A 614 in good condition can still command an asking price over 1000 USD. If you want to dig deeper, the 614 manual is on TekWiki. You’ll have to search manually because KZfaq rejects links. It is a beautiful manual from the days when manuals were substantial and meant to provide deep instruction on the application, care and repair of instruments.

Was about to buy new meters too but changed my mind. For the same money (sometimes less) i get "old" meters with 6 1/2 or 7 1/2 digits (hp, solartron, fluke) from closing companies or used marked if lucky. They may lack "modern features" but hell ... the references are well burned in. I check my meters for calibration every year (or lets say, a company does check them for me with known references) and they don't seem to drift at all or not noticeable. I love it! I will still pay every year for calibration though. Just in case. Oh and regarding the video title ... these old meters sometimes have a huge input impedance. Just more love for these old kings.

You also could have used a nanoSiemens measurement function on one of many higher end DMM's such as a Fluke 80 Series, Brymen 869S, or some Agilent meters as well. They can measure conductance to 0.01nS, which is the equivalent of 100 Gigaohms. They would display about a 0.05nS value when connected to the Uni-T when it is set to a lower voltage scale and faster sampling rate.

Not bad, but for $20 I can buy a 4 ohm 120 watt Pace 1131-0032-P1 Ultra Wave Tip and expect its iron plating to last 30 times longer. Make your own handle easy (it stays cool) and solder a cable to the gold pads on the end and use a 555 to PWM a MosFet to set temp. Works between 8v and 24v without problem (just be sure to limit Vcc to the 555 to 12v with a Zener diode).

And now if you count the time invested you are way outside of the price range. Realistically speaking this offers TS100-esque performance at half the price. Personally I will always stick to a reliable brand, heavy duty desk iron (JBC in my case) for most soldering, but this is a great little thing to have just to throw in a bag in case you need to do soldering on the go. Additionally it lowers the barrier to entry for newcomers to electronics, which is always great. I remember many years ago when I was starting out, that the options for soldering irons were either grandpas beaten down, straight in the wall plugged massive iron, or shell out big bucks for a weller (not affordable for most kids). I am glad with irons like this opening up possibilities.

@@tHaH4x0r Pace is an older and more reputable brand than JBC. Read Dave Jones on the EEVblog forum or watch his videos in the last 4 years.. He has both JBC and Pace and in almost every video one's used, it's the Pace. He reports the tip iron durability is better than JBC and if you really know electronics, PWMing a MOSFET is not hard.

@tHaH4x0r 3 күн бұрын
@@kwpctek9190 What exactly does pace vs jbc have anything to do with my comment? I have used both as well (among other brands) and I prefer JBC. In the end its a question of personal preference, not better or worse. This is not as simple as 'just PWMing a mosfet', as the heat in the element corresponds to current, not voltage. Hence you want to do current control with feedback from the thermocouple in the tip. If you dont have feedback, you will suffer from tremendously reduced performance, and negate all the advantages that such an integrated sensor/heater tip unit has. The close thermal coupling between sensor heater and contact zone makes the control able to regulate things much more tightly. If you want to hack something together, and only have it working in feedforward or substandard feedback, sure its doable (but will still cost you quite a lot of time to make it usable and robust for every day usage). If you want to do it properly, you have to put in even more effort. And that is exactly my point. If you buy a reputable big brand tip, and a handle, and the electronics required to drive it, and add up the time to get that working, you are far, far out of the budget range of the iron presented in the video, nor will it be as compact and portable.

Hi Kerry, thank toy for a very interesting Video, you confirmed what I thought the construction was inside the cell. Here in Sweden I bought a similar product with the brand name XOXOPO, the AA cells are rated at 1850 mAhr together with a charger that is driven by a 5V USB cable. The instructions specifically say do not use the charger for any other cell type (such as NiMH). I am using the cells for driving an electric toothbrush, so the regulator noise does not bother its operation, at least I get 1.5 V which works great, as compared with when you use NiMN cells which have an output voltage of 1.2 and as a consequence runs slow. I have done capacity tests on these cells and at 200mA load they gave a performance of a little more than the rated 1850 mAhr. It will be interesting to see how long the cells last.
