True RMS digital AC/DC clamp meter – VA311B
The VA311B digital clamp meter (3¾ digits / 3999 counts) is an advanced True RMS measuring instrument designed for non-intrusive measurement of both AC and DC current up to 1000 A using clamp jaws (400.0 A and 1000 A ranges). The instrument also enables accurate measurement of DC voltage and True RMS AC voltage up to 1000 V, resistance up to 40 MΩ, capacitance up to 4 mF, frequency (logic and linear, via clamp jaws or input terminals) and temperature (−200°C to 1200°C). It also features non-contact voltage detection (NCV / EF). The device is designed for power engineering, photovoltaic installations, electric vehicles (EV), automotive applications and industrial automation.
