The quality may be much better now, but a few years back I bought what looked like a cheap Chinese knock-off of a Fluke with some nice added functions. However, it was very poorly calibrated and had a bunch of interacting pot adjustments that made it a major chore to calibrate properly. Not being very patient, I used it uncalibrated with mental correction of readings until about a year ago when I spent the time to recal it.
That is rather tasty -- but it's $36 from Amazon, which seems a bit steep considering the price tag of the JayCar offering...
Why don't you get one and let us know which is better value? (I am happy to spend your money!).
Seriously though I would like to know how well the Jaycar ones perform. We have had subcontractors who used non-name brand meters only to find that they stopped working at inopportune times and then called us in to try and debug why the product didn't work. Plugged in a Fluke and the measurement was fine.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
