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)
Electrical Specifications: Accuracy is ±(% reading digits + number of digits) or otherwise specified, at 23 °C ± 5 °C & less than 75% R.H.
True RMS Models ACD-16 TRMS-PRO ACV & ACA clamp-on accuracies are specified from 5% to 100% of range or otherwise specified.
Maximum Crest Factor are as specified below, & with frequency spectrums, besides fundamentals, fall within the meter specified AC
bandwidth for non-sinusoidal waveforms. Fundamentals are specified at 50Hz and 60Hz.
