Description
Description
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.
Delivery Scope
testo 770-1 TRMS clamp meter, including battery, 1 set of measuring cables (0590 0010), instruction manual.
