*The information above is only valid for independent test equipment.

*The system is also available with production line testing solution.

*With Rogowski coils, the stray inductance of system loop reaches under 40nH, without considering the stray inductance of modules and fixtures; Pearson sensor is available as well, but the stray inductance may be higher than that of Rogowski coils.
