Safely measure current and voltage transmission in your cables with the 770-3 clamp meter from Testo. Its hinged jaw reads current directly, eliminating the need to cut the wire or turn off the circuit for added convenience. It's compatible with both AC (alternating current) and DC (direct current), so you can use it for a range of applications. This unit also measures resistance, frequency, capacitance and temperature for increased versatility. As it's a true RMS (root mean square) measuring unit, it effectively reads both regular and irregular loads for enhanced accuracy.
