1. 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)
• Accuracy is not specified for ACA measurement made BEYOND jaw
marking lines (toward jaws opening)
