| Calibrations |  |
| The instruments for quality inspections have to be calibrated from time to time. As time goes by, the use of instruments can lead to a decrease in the exactness of measurements. If instruments are not calibrated and continue to be used for tests, the inspection results will be misleading. The time of calibration depends on the values you entered in the Interval Type field and the Interval [Days/Times Used] field in the Instruments (qmptc0108m000) session. To configure calibrations in Quality: Use the Calibrate Instruments (qmptc3201m000) session to select the instruments that must be calibrated. Instruments will only be selected if the time interval or times used interval defined in the Instruments (qmptc0108m000) session has elapsed. These instruments will be blocked for calibration. Consequently the Blocked for Calibration check box in the Instruments (qmptc0108m000) details session will be selected. The Instrument Calibration Dates (qmptc3202m000) session shows the instruments that are blocked for calibration. After the instruments are calibrated, you must enter the calibration date in this session. You can unblock the instruments for which a calibration date was entered. For each instrument, a history of calibration dates is kept in the Instrument Calibration History (qmptc3500m000) session, based on the instrument and/or the date. This calibration history can be deleted based on instruments and dates in the Delete Calibration History (qmptc3200m000) session. |
