When installing instrumentation, cable is run from the marshelling cabinet, or some control system to the instrument in the field. The act of attaching the cables to the actual electrical terminals of the instrument or input output terminal at the Transmitting or receiving end is called Terminating the instrument. I.E instrument termination. Usually the instrument loop is installed in stages, where the instrument is physically mounted in the field, cable is pulled and run in cable trays or buried in trenches, and the ends of the cables are terminated.
Once prior to completely terminating a loop, the cable run is normally loop tested. I.e. Point to Point continuity checked. Once the cable is found to be good, and the instrument terminated, calibrated and tested to be functioning at the control system, the instrument is said to be commissioned. I.e ready for service. That is called commissioning. Usually commissioning forms a entire stage/phase of its own in a project.

Answer / jatin
commissioning of instrument has to deal with many steps. Availability of Cable tray and trenches. Laying of cable from Instrument to Junction Boxes and then Junction Boses to Marshalling Cabinet, which are connected with DCS/PCS controller. After laying of cables termination has to be done. which can be checked with the continuity of cable. the commissioning of instrument is still pending. The loop checking has to be performed for successful commissioning.
