Use this option to map different part-parameter links to the instrument for which Linearity study is to be carried out. Parts selected should be throughout the operating range of the measurement instrument.
The local machine will display all studies mapped on that machine. Once trials for a study are complete, mapping details will not be displayed in this screen.
Click Add to add a new record. Select Instrument Code from the drop down list displayed from the Instrument master. Study Date displays the current date. Select a date not less than the current date, if required.
Specify the Reading Mode – whether Automatic or Manual. It is set to Automatic by default. Enter Process Variation. This is the standard deviation and is used for calculating Linearity and Percentage Linearity to Process Variation.
Select Decimals and No. Of Trials by clicking the up or down arrow attached to the fields. The default value for Decimals is 0 and No. Of Trials has a value between 5 and 30.
Process variation is added to calculate %EV i.e. to determine the repeatability is acceptable.
You must enter links in the grid. Links are parts selected throughout the operating range of the instrument. Enter Part in the first column, Parameter for the part in the second column and Master Value for the part and parameter in the third column. You can enter multiple parameters for a part and multiple parts can have the same parameter. The same part-parameter combination can be entered only once.
You can define only as many parameters to an instrument on a study date for a particular part as are specified for the interface code of the instrument.
Click Save to save the record.
Click Modify to make changes. You can modify Decimals, Reading Mode, Master Value, No. Of Trials and Process Variation only if trials have not begun for the selected Instrument. If some readings have been taken for the selected Instrument then you can modify only Decimals and Reading Mode.
Click Measure if you wish to go to the Linearity Measurement screen to record readings. Measurements can be taken for all links of the selected instrument and study date .
After taking all readings which are specified in the No. Of Trials field for the selected Study, that particular study will get closed. The data related to this study is then transferred to the Linearity Data Analysis screen.
Click Delete to delete a record. You can delete a record for a Local Machine only if trials have not begun for it. For deleting a record, you must specify the Instrument Code and Study Date by selecting them from the respective drop down lists.
