The Testo 770-3 clamp meter is the ideal clamp amperemeter for demanding measuring tasks in tight application environments. The movable pincer arm can be fully retracted into the instrument. This enables the instrument to grab tightly packed cables in a particularly accurate way. In addition, more specialized applications can be handled using the clamp meter, such as starting current, power, and measurements. The optionally available temperature adapter for thermocouple probes can be used to measure electrical parameters as well as temperatures (compatible type K thermocouple probes can be ordered separately). The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode, and capacitance. This makes operations easier and more reliable than ever before. Your readings are clearly and distinctly presented on the two-line display. In addition to this, the Testo 770-3 offers a performance measurement function and can be connected via Bluetooth to the Testo Smart App. In the App, the measurement curve can be displayed as a graph on your smartphone/tablet and directly documented in the report.
