The ADR 4000 is a portable and multifunctional multi-metering device whose main function is to perform accuracy tests.


This three-phase device uses Clamps (CTs) to measure the consumer unit load during the test, eliminating the need to interrupt your power supply. With tables and real-time graphs (phasorial and linear) of average and instantaneous values per phase and totals, field technicians have access to valuable data for in-depth analysis, for both electronic and electromechanical meters (single-phase, two-phase, and three-phase).

The Bluetooth communication capability enables remote operation of the equipment through a tablet or smartphone via a dedicated Android app, and on-site report printing, making the process more efficient and convenient.
