Indication: Bar graph segments & audible beep tones proportional to the field strength
Detection Frequency: 50/60Hz
Detection Antenna: Top side of the stationary jaw
Probe-Contact EF-Detection: For more precise indication of live wires, use the Red (+) probe for
direct contact measurements

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)
