In this video I cover the following:
* The Fluke 8846A has arrived in South Africa thanks to Comtest (www.comtest.co.za). I have the opportunity of visiting the Eskom calibration lab with the Fluke 8846A to see if it is within specified calibration tolerance.
* We take a look at the update to my multimeter reference check project.
* I discuss the next project - an electronic DC "dummy" load based on Warwick's work:

The basic circuit is from Dave Jones EEVBlog:

* I chat about getting stuck into some Arduino projects and tutorials soon.
* I talk about a suggestion by one of my viewers (spikeguns1) about potting or encapsulating a circuit board to provide a better temperature coefficient. I may experiment with mineral oil in this regard as it is non-conductive.
