Top-model True-RMS AC/DC clamp meter with a retractable slide-clamp arm, power measurement, a 1000 V range, and a Bluetooth interface to the testo Smart App. measureQuick integration must be confirmed with mQ directly.
Visit tool →The testo 770-3 is the top model of the testo 770 clamp-meter range: a True-RMS AC/DC clamp meter with a retractable slide-clamp pincer arm for grabbing the correct wire in tightly packed cables and panels. It performs automatic AC/DC parameter recognition and adds, over the lower 770-1 and 770-2 models, output-rating power measurement, an extended 1000 V voltage range, a 600 A current range, microamp measurement, Type-K temperature, and a Bluetooth interface to the testo Smart App and other Testo instruments. It also measures resistance, continuity, diode, capacitance, frequency, and inrush current on a 6000-count display rated CAT IV 600 V and CAT III 1000 V. It is part of Testo's Smart-App Bluetooth ecosystem, but direct measureQuick integration is not verified and must be confirmed with mQ directly before publishing.
