Specified accuracy is for ACA clamp measurement at the center of jaws. When the
1)
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)
Add 1% to specified accuracy @ ACA fundamental < 5A or ACV fundamental < 90V.
2)
Accuracy is not specified @ ACA fundamental < 1A or ACV fundamental < 30V
Add 1% to specified accuracy @ ACA fundamental < 5A or ACV fundamental < 90V.
3)
Accuracy is not specified @ ACA fundamental < 2A or ACV fundamental < 50V
A-lags
Indication:
1)
"A-lags" LCD annunciator turns on to indicate an inductive circuit, or Current A lags
Voltage V (i.e., phase-shift angle θ is "+").
A-lags Indication is specified at 50/60Hz fundamental without harmonics, and at ACV >
1)
90V, ACA > 9A, & PF < 0.95
