The UT200B+ is a handheld auto-ranging true RMS AC clamp meter designed for reliable electronic and electrical diagnostics. It measures AC current up to 600 A, DC/AC voltage up to 600 V, and includes high voltage frequency measurement, one‑button LIVE line measurement, and automatic diode/conduction identification. With over‑voltage and over‑current audible/visual alerts, as well as full protection against misoperation, it offers a balanced combination of safety, accuracy, and value for professional electrical and electronic testing.
