ACA AutoVATM 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)
