The type of service that is provided by ARPO consists of carrying out a series of tests aimed to verify the correct operation of any control and/or safety system at the client facilities. This service includes the development and review of a system-specific test protocol, previously approved by the client and supported by international codes and standards applicable to the particular system.

These tests validate the dynamic behavior of the tested system using field equipment and elements under the client process conditions; it also takes into account the tuning of each control loop which integrate the system being tested, the instrument ranges final configurations, alarms, timers and counters involved in the programmed control strategies for the system being tested, as well as logic settings and programming required by some final process requirement.
