Dual-range accuracy
The ADT762W can automatically switch between internal calibration ranges according to actual control pressure. Additel supplies dedicated calibrations for range pairs (e.g. 0–200 & 0–700 bar or 0–400 & 0–1000 bar). Range selection can be set to automatic or chosen manually by the operator.

Integrated auto‑purge
Automatic purge system for rapid removal of air from the hydraulic circuit, simplifying setup and reducing time and maintenance.

Dual‑port manifold with fluid management
The unit is designed for use with deionized water only. It includes a supplied manifold and a fluid management system to reduce stagnant water and evacuate residual water after venting to extend service life and lower maintenance costs.

Documented task functionality
The built‑in task application lets users create, store and execute calibration procedures without a PC: automatic error analysis, test report generation and local result storage (up to 1,000 documented tasks and 1,000,000 timestamped readings).

HART bimode communication
Full support for HART transmitters: read, configure and calibrate directly from the ADT762W in automatic or manual HART mode. DD files updated periodically.
