High current measurement capabilities(Using
Hall effect current ratio box )
+/-0.2 % at 10Amps rising to +/- 0.5
% at 150 Amps direct current.
+/- 1.5 % from 2 Amps to 20
Amps over the range 40Hz to 3KHz
Hall effect devices give galanic isolation
from the current source.
High currents are used in earth bonding testers.
