Amprobe ACDC-54NAV [3729989] 1000A AC/DC Navigator™ Clamp Meter with Temperature. The Amprobe ACD-54NAV clamp-on power meter offers AC/DC current measurements. This clamp-on multimeter offers a full range of power quality diagnostics including power and power factor, total harmonics distortion, individual harmonics, in-rush current, phase sequence, TRMS and low pass filter for industrial power monitoring and verifying system conditions. The ACD54NAV measures AC/DC current to 1000A, AC/DC voltage to 1000V, temperature, resistance, frequency, and capacitance. Other features of the ACD-54NAV include non-contact voltage detection which enhances safety, a large backlit digital display with analog bar graph, and an in-jaw flashlight that automatically lights when jaws open to illuminate dark panels and wide jaws to handle large conductors up to 1.6" (40mm) for high voltage industrial environments.
