In this video we demo our third hands from AliExpress: Octopus Soldering Helping Hands Bench Vise Table Clamp with Flexible Arms Solder Iron Holder PCB Repair for TS101 TS100 PINE64.

I mention that I found a YouTube video which has a look at it: Octopus Hand supports Soldering for only 5$ – Turtle Review but like me they couldn’t figure out what the rubber and bolts on the base are for! If you know please let me know in the comments!

Demo #5: Peak Electronic Design Atlas LCR45 – LCR Component Meter with Impedance Measurement

In this video we take a look at my new Peak Electronic Design Atlas LCR45 LCR Meter.

If you’re interested I have other equipment from Peak Electronic Design.

Over on the EEVblog forum I ask What’s special about the frequency 14.9254 kHz? The answer seems to be that this is 1/67th of 1 MHz, which is probably as precise as the microcontroller they’re using can go.

You can learn more about my ALKOY Capacitor Discharge Pen.

There are accessories available for the LCR45. Stuff I am planning to get includes:

I would get the LX30 – Extension Cable for LCR40/45 but it doesn’t appear to be in stock.

There are cases available but I am not planning to get any of those:

Demo #4: ANENG A3005 4000 Count Pen Type Handheld Multimeter | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

In this video we demo the ANENG A3005 Pen Type Handheld Multimeter. This pen-type multimeter can do voltage, resistance, continuity, and diode testing, among other functions. It’s a 4000 count device, meaning it can display about three and a half significant digits, for instance values such as 3,999 or 3.999 or 0.001.

If you’re interested you can check out all of my equipment from ANENG. They make good stuff! Of particular note is my ANENG AN-999S Bench Multimeter and my ANENG BT189 Battery Tester.

If you’re interested in any of this tech you can find it at AliExpress:

Demo #3: Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

In this video we put the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer through its paces.

My notes about this device are on my personal wiki, here: Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer.

The DCA75 can measure triac and thyristor devices but the Peak Electronic Design Atlas SCR100 Triac And Thyristor Analyzer can do a better job of it.

If you want to measure zener diodes the DCA75 can do it but the Peak Electronic Design Atlas ZEN50 Zener Diode Analyzer can do a better job of it.

While reading the manual we learn about the PCA23 SOT-23 test adapter, while searching for that I found this behind-the-scenes deeplink from Peak Electronic Design: https://www.peakelec.co.uk/resources/pca23.html

The manual mentions the International Electrotechnical Commission – IEC 60617 – Graphical Symbols for Diagrams, which is an international standard for graphical symbols of electromechanical devices.

The support page is DCA75 (DCA Pro) Support, from there you can download software/firmware.

Demo #2: Resistor Box Banana Plug Modding and Demo | Learning Electronics In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

You can support this channel on Patreon: patreon.com/JohnElliotV

In this video I mod a pair of resistor boxes by installing banana plug terminals in place of the lug terminals they came with and then I give a quick demo of them.

In the demo we connect them in both series and parallel and then measure their resistance with my Fluke multimeter.

I mention this video from Dave Jones on the EEVblog: EEVblog #1020 – Is A $7 LCR / Component Tester Any Good? which is where I found out about the RS-201W resistor box which he has. I searched on eBay for RS-201W but what I found for over US$1,000 (inc shipping) was way too expensive: IET Labs RS-201W Wide Range Precision Resistance Substituter.

Demo #1: How to Use All the Features of the Fluke 17B+ Digital Multimeter | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

You can support this channel on Patreon: patreon.com/JohnElliotV

In this video I take a look at how to use all of the features of my new Fluke 17B+ Digital Multimeter.

This is the inaugural demo video. We now do an ‘unboxing’ and a ‘demo’ separately. In the demo videos we try to take a close look at each feature of a product. Whereas with the unboxing we just make a record of the unboxing experience and take a cursory look at a few features.

If you’re interested in the Fluke 17B+ then in addition to watching this demonstration video you might also like to see the unboxing: Unboxing #14: Unboxing of Fluke 17B+ Multimeter | Learning Electronics In The Lab With Jay Jay.

The slides for this video are here: https://www.jj5.net/fluke-17b-plus/

In the video we cover:

  • high current fuse test
  • low current fuse test
  • AC voltage measurement
  • DC voltage measurement
  • DC millivolts measurement
  • AC current measurement
  • DC current measurement (including milliamps and microamps)
  • continuity testing
  • diode testing (with forward bias measurement)
  • resistance measurement
  • capacitance measurement
  • temperature measurement
  • frequency measurement (10 Hz to 400 kHz)
  • duty cycle measurement (of regular sine wave)
  • relative measurement feature
  • measurement hold feature
  • backlight usage
  • min/max measurement

We were lead astray by the slide for the current test which indicates the wrong terminal for the current measurement! I got these slides from Fluke in the 15B/17B/18B | Quick reference guide on the Manuals+resources tab on their documentation for the Fluke 17B+ Digital Multimeter. So it is pretty disappointing that the official Fluke documentation led me astray like that! But we figured it out in the end so all is well that ends well.

Errata: at around the 24 minute mark I try to introduce a load across my 9 V AC input voltage but I don’t correctly wire it in. So when I think I’m testing with a load attached there is in fact no load attached.
