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)

Add 1% to specified accuracy @ ACA fundamental < 5A or ACV fundamental < 90V.

Accuracy is not specified @ ACA fundamental < 1A or ACV fundamental < 30V

Add 1% to specified accuracy @ ACA fundamental < 5A or ACV fundamental < 90V.

Accuracy is not specified @ ACA fundamental < 2A or ACV fundamental < 50V

A-lags

Indication:

“A-lags” LCD annunciator turns on to indicate an inductive circuit, or Current A lags

Voltage V (i.e., phase-shift angle

is “+”).

A-lags Indication is specified at 50/60Hz fundamental without harmonics, and at ACV >

90V, ACA > 9A, & PF < 0.95
