Chauvin Arnoux PAC 26 [P01120126]  0.5 - 1000A AC/ 0.5 - 1400A DC AC/DC Clamp Meter Adapter. The PAC26 model accurately measures AC or DC currents by making use of the Hall effect principle. This clamp with mV output is equipped with an automatic DC zero system and a deactivatable Auto Power Off (APO) function. It can be powered by a standard mains power pack via a Micro USB connector. The PAC clamps are professional current clamps capable of measuring alternating and direct currents. The two jaw shapes proposed enable users to clamp cables or small busbars. Making use of the Hall effect principle, the models in the PAC 10 Series measure up to 400 A AC and 600 A DC, while those in the PAC 20 Series measure up to 1000 A AC and 1400 A DC. Powered by a battery or a standard external power supply (option) via their micro-USB connector, the PAC clamps are all equipped with a Zero DC reset function and a deactivatable Auto Power Off (APO) function. The PAC 15 and PAC 25 models are a unique range whose 1  mV/A sensitivity allows "direct" readings on the associated multimeter. The PAC 16 and PAC 26 models offer a second 10 mV/A calibre which is more sensitive. The PAC 17 and PAC 27 models, also called "isolated current probes", offer two calibres and are equipped with a coaxial lead and isolated BNC connections for direct connection to an oscilloscope, allowing users to view the waveform and amplitude of the current.
