The Testo 770-1 clamp meter allows you to measure current without contact on tightly packed power cables or conductors.
Thanks to its unique gripping mechanism, it can grasp each cable easily and securely.
It automatically determines and selects other electrical parameters such as AC/DC and resistance, continuity, diode capacitance.
With its large 2-line LCD screen, you can easily read measurement data in low-light environments.
You can also use the Testo 770-1 clamp meter for inrush current measurement.
For maximum flexibility, the clamp arm of the device can be completely retracted.
You can easily capture tightly packed cables in switch cabinets without any hassle.
The use of Testo 770-1 clamp meter is very easy and reliable.
