Testo 770-3 Bluetooth True RMS Clamp Meter

The Testo 770-3 True RMS Clamp Meter is the most advanced clamp meter in Testo’s 770 range. It boasts a whole range of advanced features for measurement, practical use and data processing. Most importantly, it measures all basic electrical variables including AC/DC voltage, AC/DC current, resistance, frequency, temperature, and capacitance as well as performing diode test and continuity testing. The Testo 770-3’s auto-calculation capabilities allow it to give an additional reading for power. The True RMS readings give the device a basic accuracy of ±0.1%.

The main physical feature of the Testo 770-3 is the retractable pincer clamp. This unique design features a completely retractable pincer jaw coupled with a traditional hard jaw which allows the user to access awkward wiring as shown in the video. Further practicality is added by the Testo 770-3’s auto detection feature. This can sense AC or DC voltage/current as well as automatically selecting the appropriate variables to measure, thus saving time and preventing mistakes. Advanced measurement features include Inrush current for start-up phases, Min/Max and data hold so the user gets a comprehensive overview of an object device’s performance. Real-time measurements are shown on the Testo 770-3's backlit, two-line display as well as on a smartphone or tablet via the Testo Smart Probes App.

The Testo 770-3’s Bluetooth connectivity makes it stand out from other clamp meters because it means that the device is compatible with the Testo Smart Probes App on an Android or iOS smartphone/tablet. This means that readings can be displayed directly on the smartphone’s screen and instant access to the App’s data analysis and processing functions allows the user to create detailed, paperless reports within minutes on site.

Overall, the Testo 770-3’s large range of advanced features allows comprehensive measurement of many different variables whilst great care has been taken to ensure that the product is easy to use. From the pincer clamp to the Bluetooth connectivity, the user can easily take readings and analyse them with Testo 770-3.
