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

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…
