Uncertainty Specifications
The specifications apply from Full Rate Current down to 10 % of the full rated current. For example the
300 A Range can be used from 300 A down to 30 A or the 100 A Range can be used down to 10 A.
Ensure current cables used can handle the full rated current.

C referred to the unit of resistance as maintained by a National Metrology Institute, and expressed as a
deviation from nominal with a total uncertainty and coverage factor of k = 2.
Note 2: A traceable report of calibration stating the measured values and uncertainty is provided with each unit at test currents of 1/10 of
rated current and full rated current to a maximum of 100A and a minimum of 0.1 mA,
