I’m sorry but i really don’t understand the calibration for the emontx shield with arduino
(i’am french, i understand all the words…but not the meaning of the procedure)
this is in my sketch “emonTX Shield CT123 Voltage”
if (CT1) ct1.voltage(0, 260, 1.7);
i am in france in the euro aera and i have the ideal power adaptator for the 9v AC. so 260 is the good value
the emon tx send me a mesure of 255 v
in real i have nearly between 239.5 and 240.5 v
so what do i have to change ?
the 260 value ?
the 1.7 value (what it is ?)
other question not in this theme, is it normal that i mesure some what if i only have the SCt plugged ? like 12w ?
thanks for your answer
