True RMS models Crest Factor:
< 2.5 : 1 at full scale & < 5.0 : 1 at half scale for 40.00A & 400.0A ranges
< 1.4 : 1 at full scale & < 2.8 : 1 at half scale for 1000A range
1)
Add 8d to specified accuracy while reading is below 10% 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)
