The data sheet and the technical reference state that for mSure auto calibration to work, the device only needs to be powered which seems a bit like stating the obvious to me.
However, I couldn't find anything about the required conditions on the "hot" side.
- Does the mains voltage needs to be present? I presume yes but I'm not sure.
- If so, does any load needs to be present?
- If yes, does it matter what type of load or is a simple resistive load (e.g. incandescence lamp) OK?
- Any minimum power requirement for the load?
Thanks for any help on these topics.
