Having recently gotten my emonTx up and running, I’m wondering about the implications and use of the high sensitivity CT4 port. I’m in the US and using CT1 and CT2 for mains, with CT3 and CT4 tracking branch circuits of interest. The readings on CT4 appear to be similar in nature (baring differences in load, of course) to what comes from the other ports.
I can’t find any docs in Learn or Resources that cover what “high sensitivity” means from a practical effect. Is this just a limit on the max power monitored on that port? Is this port capable of higher-period samples and, if so, how is that enabled in either the emonTx sketch or in the corresponding emonBase unit?
Thank in advance for the help and clarification!
