When is an initial calibration file supposed to be installed on a DCS using InPower BPU?

The initial calibration file is intended to be installed on a Distributed Control System (DCS) using InPower BPU when there is no previous capture file available. This situation typically arises when a new BPU is installed or when the system has been reset to factory settings, requiring a fresh calibration setup to ensure that the control system can operate accurately and respond correctly to the inputs it receives.

Having an initial calibration file is crucial for the proper functioning of the system, as it contains baseline data and configuration settings specific to the equipment being monitored and controlled. Without a previous capture file, the DCS lacks this essential reference point, which can lead to improper system behavior or incorrect operations.

In instances like scheduled preventative maintenance, fault occurrences, or after a specific run-time threshold, while recalibrations may be necessary, the initial calibration specifically addresses the absence of prior calibration data. Therefore, the installation of the initial calibration file should happen when there's no existing capture file to reference.
