Threshold: 1A AC (40Hz ~ 500Hz only) nominal
Crest Factor:
< 3 : 1 at full scale & < 6 : 1 at half scale for 40.00A, 400.0A & 600A ranges
1)
Induced error from adjacent current-carrying conductor: < 0.06A/A
2)
Specified accuracy is from 1% to 100% of range and for measurements made at the
jaw center. When the conductor is not positioned at the jaw center, position errors
introduced are:
Add 1% to specified accuracy for measurements made WITHIN jaw marking lines (away
from jaw opening)
Add 4% to specified accuracy for measurements made BEYOND jaw marking
lines (toward jaws opening)

Specified accuracy is for ACA clamp measurement at the center of jaws. When the
conductor is not positioned at the jaw center, position errors introduced are:
Add 1% to specified accuracy for ACA measurements made WITHIN jaw marking lines
(away from jaw opening)
