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.

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.

In this video I add improved debouncing logic to the inaugural Silicon Chip and Jaycar Mini Project: JMP001.

Shout out and thank you to Tim Blythman for developing this project.

You can see Tim’s original code and my updates which improve the debouncing implementation.

In the video I mention that we use the pgmspace.h header from Arduino.

In this video I use and mention my Jackcat Electric Scissors.

Also I managed to get my air-quality meter to work by squeezing it together with a clamp. It’s not pretty, but it works!

That red clamp you can see bottom left is holding the screen together and causing it to work…

In this video I unbox my new Fluke 17B+ Digital Multimeter.

The hard copy manual which was in the box I received was in Chinese (I think) but I found the English documentation available on the web from the manufacturer over here: Fluke 17B+ Digital Multimeter.

Shoutout to my mate @ElectrArc240 who was the person that made me aware of this Fluke multimeter, I learned about it in one of his videos.

If you enjoyed this video and are interested in the Fluke 17B+ you can see a product demonstration over here: Demo #1: How to Use All the Features of the Fluke 17B+ Digital Multimeter | In The Lab With Jay Jay.

Interlude #8: Making My Maker Faire ‘Here There Be Makers’ Badge | In The Lab With Jay Jay

In this video I fix up and reassemble my Here There Be Makers badge which I received from Maker Shed in California.

John's Makers PCB badge

This electrified badge was made by lectrify.it and PCBWay.

Previously I had installed a single 3mm LED in the top of this thing, but in this video I remove that (so I can use the hole to hang it) and install two 3mm LEDs on the front instead, which is my best guess as to what I was supposed to do with this thing, which didn’t come with instructions.

There is some information about their Maker Faire event on in San Fransisco later this year over here: https://make.co/welcome/

And also, yes, I should have combed my hair before making this video. :P
