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)
2)
Add 4d to specified accuracy for 3-Phase Balanced-Load Power measurements.
3)
Add 1% to specified accuracy @ ACA fundamental < 6A or ACV fundamental < 90V.
Accuracy is not specified @ ACA fundamental < 1A or ACV fundamental < 30V
4)
Add 1% to specified accuracy @ ACA fundamental < 6A or ACV fundamental < 90V.
Accuracy is not specified @ ACA fundamental < 2A or ACV fundamental < 50V
