Client is a contractor that provides calibration and maintenance services to a number of industrial customers. In this case the service is to ambient gas quality sensing for monitoring and alarm. This is a personal safety function that requires periodic testing, typically every 3 or 6 months. Complete and accurate records of testing and maintenance are required. Clear and concise customer reports are also required. The Admin Application is the repository for all collected data. As part of the dispatch process, relevant data is extracted (copied) from the Admin Application and transmitted to the Leader Application where new data is input. On completion of work the new data generated is uploaded to the Admin Application where it is audited before being added to the existing data. The Leader Application that is used under field conditions, makes extensive use of pull-down selections for data entry in order to: minimize errors, reduce data entry time and provide consistent data to simplify analysis.
Future use of this information will be to identify repeat offenders (so proactive corrective action can be initiated), adjust inventory levels- the life of a sensor is highly dependent on environment. We may occasionally need to print a Tag Number history (Marsh Letterhead, company header, instrument header, chronology: sort by date, event (calibration, repair/replace including new serial number and comments).Regarding Gas Record Data Bases- all information input by Operator except as noted. Should be a separate screen for each data base,Customer data base.
