Introduction Testo 770 – 3 – Clamp meter
The testo 770-3, in addition to the features of the other meters in the testo 770 series, includes real-time power measurements (Watts), power factor, and Bluetooth. The Testo app can be used for remote viewing, monitoring, data logging, and creating reports. This powerful app allows you to create custom reports that include photos, data, and graphs that can be saved, or sent via email.
The Testo 770-3 clamp meter is a highly advanced tool designed for professional electricians and technicians. It features Bluetooth connectivity for seamless data transfer to the Testo Smart Probes App, enabling easy analysis and reporting. The fully retractable pincer arm allows for effortless clamping around tightly packed wires without disconnecting the circuit.
The large backlit display ensures clear visibility in various lighting conditions. The device also offers a wide range of measurement functions, such as voltage, current, resistance, capacitance, frequency, and temperature. Enhanced safety is provided by the non-contact voltage detection feature.
With comprehensive power measurement functions, including real, apparent, and reactive power, the Testo 770-3 provides detailed insights into electrical systems. It utilizes True RMS measurement for accurate readings with non-linear loads and distorted waveforms, and includes inrush current measurement for diagnosing start-up issues.
