Notes:
* For 2.5Ω or 5Ω Burden Resistor, <5% of Ipn, Nd<±3dB, DC to f.
** Busbar noise measured on primary cable with one turn
All ppm figures refer to primary current (DC or Ipn). For programmable current transducers refer to highest achievable primary current, example given IT 700-S programmed to 160A the ppm figure refers to the 700A that is achievable.
