"The unique pincer clamp helps the user reach awkward wiring in cramped conditions"

  • Description

    Testo 770-1 True RMS Clamp Meter

    The most prominent physical feature of the Testo 770-1 True RMS Clamp Meter is its fully retractable pincer clamp. This pincer aids the user by bringing access to very tight wiring because, without the obstacle of a hard jaw, the fixed part of the clamp can be easily inserted behind a wire before the retractable pincer section comes up to meet it (watch the video to see this in action). This is especially useful when taking readings inside wiring cabinets and other awkward locations.

    In addition to its unique retractable clamp, the Testo 770-1 effectively and accurately performs all the major functions required of a clamp meter over impressive measurement ranges. Readings can be taken for AC/DC voltage, AC/DC current, resistance, frequency and capacitance whilst there are also options for continuity and diode testing.

    The TRMS measurement function means that readings are accurate whilst the device also automatically detects whether current or voltage is AC or DC so readings take less time and risk fewer mistakes. Alongside measurement functions such as Inrush current measurement, hold and Min/Max, automatic parameter detection extends to diode, resistance, capacitance and continuity, thus making the Testo 770-1 extremely user-friendly.

    The two-line display allows the user to view two real-time readings at once and the device is light, small and portable. Overall, it brings accuracy and practicality to measuring several different electrical variables through its unique pincer clamp.
