Accuracy
The intrinsic error is expressed as a ± % of reading (rdg) and in measurement counts
(counts).

(3) Accuracy given from 0 to 90% of the range
From 90 to 100% of the range: 5% max
NB : It is the form of the jaws, thus the cable clamping capacity, that limits the
current range of the clamp. The measurement range is greater.

Fc from 1.5 to 3: 5% rdg
Fc from 3 to 5: 12% rdg
(5) In RMS A AC up 800 A to 1000 A, accuracy 5 % rdg ± 5 pt
In A DC up 1000 A to 1400 A, accuracy 8% rdg ± 5 pt
(6) Supplementary error in A AC, depending of frequency (from 65Hz to 450Hz) : < 5%
