| # Instruments (qmptc0108m000) Use this session to display instruments that will be used to test items for specific characteristic. In the details session, you can create and/or maintain instruments. Related topics Master data, quality management Instrument A tool that is used during quality tests to measure particular characteristics of an item. Example
Instrument | acidimeter
Characteristic | pH value
Test Area The physical location where tests take place. Skill The specific know-how or technical expertise that an engineer must have to carry out activities. For example, knowledge of electricity, specific equipment, and so on. Least Measurable Quantity Unit The unit in which the least measurable value is expressed. The physical unit of the least measurable unit must be the same as that of the characteristic unit of the characteristic for which this instrument is used. Example A micrometer screw gauge. A micrometer screw gauge can measure with an exactness of 10 micrometers. Thus, micrometer can be entered in the Least Measurable Quantity Unit field and 10 in the Least Measurable Quantity field. Least Measurable Quantity The degree of exactness to which the instrument can measure. Example A micrometer screw gauge. A micrometer screw gauge can measure with an exactness of 10 micrometers. Thus, 'micrometer' can be entered in the Least Measurable Quantity Unit field and 10 in the Least Measurable Quantity field. Interval Type The interval between one calibration and the next. The interval shows when the next calibration will take place: after n days, or after n times used. Interval [Days/Times Used] Indicates when the calibration takes place. If you entered Time in the Interval Type field, type in the number of days. If you entered Number of Times Used in the Interval Type field, type in the number of times used. Blocked for Calibration If this check box is selected, you block the instrument for calibration. A blocked instrument cannot be used for inspections. An instrument is automatically blocked when it is selected for calibration in the Calibrate Instruments (qmptc3201m000) session. No calibration-related data can be maintained when an instrument is blocked. An instrument can be unblocked in the Instrument Calibration Dates (qmptc3202m000) session. Last Calibration Date The last time the instrument was calibrated. Next Calibration Date The date of the next calibration of the instrument. This field only applies if you entered Time in the Interval Type field. Next Calibration Date = Last Calibration Date+ Interval [Days/Times Used] or Next Calibration Date = current date + Interval [Days/Times Used] Next Calibration [Times Used] Indicates the number of times the instrument can be used before the next calibration. This field only applies if Number of Times Used is entered in the Interval Type field. Next Calibration [Times Used] = interval - Actual Times Used Actual Times Used The number of times or the number of days the instrument is used for testing since the last calibration. Note The value of this field is influenced by the following sessions: Sample Test Data by Characteristic (qmptc1115m000) Sample Test Data by Serial Number (qmptc1116m000) Instrument Calibration Dates (qmptc3202m000) |
