Some playing around with the Energy Micro Tiny Gecko board and software. Does it meet it's claim of 20nA standby current?
Not a formal calibration check, but playing around in the TrioSmartCal lab testing the accuracy of the Fluke 59 (Raytek MT6) Mini IR Thermometer using an Extech IRC350 (CEM BX-350) IR Calibrator.
Also playing with the Flir E60 IR Camera and Extech IR200 human body IR thermometer
