True RMS digital AC clamp meter – VA311A
The VA311A digital clamp meter (3¾ digits / 3999–4000 counts) is an advanced True RMS measuring instrument designed for safe, non-intrusive measurement of AC current up to 1000 A using clamp jaws with a maximum opening of 42 mm. 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, logic and linear frequency, and temperature (−200°C to 1200°C). It also features non-contact voltage detection (NCV / EF). The device is designed for power engineering, electrical maintenance, electrical installation and industrial servicing applications.
