Hi All,
Playing with the ZMPT101b for reading AC today.
I'm dealing with no more than 100V and calculated with the POT unwound (anticlockwise) the max sensitivity is ADC+48 for 17V.
For 100V that means I'll get +/- 282 on the mid-point which is little more than half what resolution I could be attaining. This is correct per the ZMPT101b's design of reading around the 240v mark.
So has anyone modified the design to double the gain?
Cheers
