Testo 770-1 – Clamp meter
Features:
✔ Fully retractable pincer arm for maximum flexibility
✔ Auto AC/DC
✔ Large two-line display
✔ Measures the common electrical parameters
The testo 770-1 clamp meter is ideally suited for non-contact current measurement on tightly packed power cables or conductors with a small diameter. The unique grab mechanism means you can grab each individual cable easily and safely.
Testo 770-1 – Clamp meter With this clamp meter, you can function in any application environment, regardless of how constrained. To catch closely packed cables in switching cabinets, for example, as if using a hook, the movable pincer arm can be entirely retracted inside the tool. This is the easiest measurement you’ve ever done in a confined space.
Additionally, the is now more dependable and simpler to use than ever before. It automatically recognizes and chooses AC/DC and other electrical properties like capacitance, diode, continuity, resistance, and continuity. It can also be employed to gauge the beginning current. Additionally, the two-line display makes your readings stand out and be seen clearly.
The operation of the testo 770-1 clamp meter is also easier and more reliable than ever before. It automatically detects and selects AC/DC and other electrical parameters, such as resistance, continuity, diode and capacitance. In addition, you can also use it to measure the starting current. And the two-line display presents your readings clearly and distinctly.
The Testo 770-1 Clamp Meter is a robust and versatile tool designed for professionals in the electrical, HVAC, and industrial sectors. Here are some key features and applications of the device:
