Energy consumption measurement calibration is a pain

Fig. 1.  Using the Agilent AC Power Source Analyzer to calibrate my own hardware

Last year, a lot of time was spent in calibration.

Remind me to outsource the calibration part somewhere on my next project.

Remind me that the Power Factor in any circuit cannot exceed 1.

Remind me that the cables used in my setup can only take few Amperes of current.

Remind me not to play with AC electricity anymore.

Fig. 3.  There is AC 240V going in this. Not an ordinary hardware.
