Description
Testo 770-2 Clamp Meter
Testo 770-2 makes work significantly easier in confined spaces, such as in switch cabinets. Thanks to the folding pincer jaw, which can fully retract into the housing, you can neatly clamp even tightly packed conductors individually and perform the necessary measurements.
The measured values are clearly and distinctly displayed on the backlit two-line display.
Key Features and Technical Capabilities
- Innovative Mechanism: Fully retractable (folding) pincer jaw for convenient work with tightly packed cables.
- Automation: Automatic detection of AC/DC current, as well as automatic detection of other electrical parameters (resistance, continuity, diode check, capacitance).
- Extended Current Measurements: Measurement of inrush current on electric motors.
- Sensitivity: Measurement of ionization current in the µA range.
- RMS Measurement: Measurement of True Root Mean Square (True RMS).
- Temperature Measurement: The delivery scope includes an adapter for thermocouple probes (a compatible Type K probe is ordered separately).
Application Areas Overview
- Measurement of current consumption.
- Checking for the presence/absence of voltage.
- Measurement of air ionization in heating systems.
- Checking the continuity of switches.
- Measurement of the resistance of sensors or motor coils.
- Easy temperature check.
