For test frequencies between 41 and 5087Hz, between 1 and 4 turns of the
GroundFlex
sensor, and a selection of 1 to 4 measurement channels, the
®
operating accuracies are the following:
SENSITIVITY and minimum I
S x 1/10
S x 1

(1): Valid only in the SENSITIVITY x 10 setting
The current measured depends on the number of turns of the GroundFlex
around the conductor to be measured. (e.g. if the GroundFlex
4 times around a conductor carrying a current of 1A, the input signal will be the
same as if the GroundFlex
rying a current of 4A. The operating error is therefore indicated for an input signal
current in A.tr (Ampere.turns).
The minimum current measured depends on the setting of the SENSITIVITY switch
as indicated by the table below:
