1)
Add 8d to specified accuracy if reading is below 15% of Range
2)
Induced error from adjacent current-carrying conductor: < 0.06A/A
3)
Specified accuracy is 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)
