A method for safe performance of a calibration and/or an adjusting of a measured variable of a measuring device in automation technology, especially in process analysis technology, in the case of which a calibration result or an adjusting value is ascertained and shown on a display. In order to assure reliable adjusting or calibrating of a measured variable of a measuring device, the calibration result or the adjusting value is shown in multiple instances at random locations of the display, wherein, upon agreement of all shown calibration results or adjusting values, a confirmation is effected by a user of the measuring device.
Method for safe performance of a calibration and/or an adjusting of a measured variable of a measuring device in automation technology, especially process analysis technology, in the case of which a calibration result or an adjusting value is ascertained and shown on a display (3), characterized in that the calibration result or the adjusting value is shown in multiple instances at random locations of the display (3), wherein, upon agreement of all shown calibration results or adjusting values, a confirmation is effected by a user of the measuring device (1).
Method as claimed in at least one of the preceding claims, characterized in that display of the calibration result or adjusting value occurs in different ways of writing numbers.
Method as claimed in at least one of the preceding claims, characterized in that for calibration purposes, the measured variable of the measuring device (1) is compared with a reference variable, and a deviation of the measured variable from the reference variable is ascertained as calibration result.
Method as claimed in at least one of the preceding claims, characterized in that display of the calibration result or adjusting value occurs on an on-site display (3), especially at a location of use of the measuring device (1).
Method as claimed in at least one of the preceding claims, characterized in that the confirmation of the calibration result or of the adjusting value is effected by the user by touching a button embodied as a soft key (4), whereas especially touching any additional button embodied as a soft key (5) on the display (3) leads to a rejection of the calibration result or of the adjusting value.
