Use this option to map parts and parameters to the instrument for which Bias study is to be carried out.
Once all readings for all parameters have been completed then that study is not displayed on this screen. The local machine will display all studies mapped on that machine.
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. Select Part Code from the drop down list displayed from the Part master. Select Parameter Code from the drop down list. This list contains only those parameters which have not been mapped to the selected instrument code, study date, part code and local machine.
Enter the Master Value. Specify the Reading Mode – whether Automatic or Manual. Enter Tolerance and Process Variation. At least one of these two fields must be entered.
Select Decimals and No. Of Readings by clicking the up or down arrow attached to the fields. The default value for Decimals is 0 and No. Of Readings has a value between 5 and 30.
Process variation is added to calculate %EV i.e. to determine the repeatability is acceptable.
Click Save to save the record. You can map only as many parameters as are specified for the interface code of the instrument.
Once a parameter has been mapped for an instrument, Reading Mode and No. Of Readings are set for all subsequent parameters.
Click Modify to make changes. You can modify Decimals, Reading Mode, Master Value, No. Of Readings, Tolerance and Process Variation only if readings have not begun for the selected Instrument Code, Part code and Parameter code. If some readings have been taken for the mapped part and parameter then you can modify only Decimals and Reading Mode. If you change Reading Mode or No. Of Readings for a parameter, the same change is made for all other parameters mapped to that instrument code.
Click Measure if you wish to go to the Bias Measurement screen to record readings. You must map the total number of parameters which are specified for the interface code of the instrument before you can click Measure.
After taking all readings which are specified in the No. Of Readings field for all parameters of the selected Study Date, Instrument Code and Part Code, that particular study will get closed. The data related to this study is then transferred to the Bias Data Analysis screen.
Click Delete to delete a record. You can delete a record for a Local Machine only if readings have not begun for it. For deleting a record, you must specify the Instrument Code, Study Date, Part Code and its corresponding Parameter by selecting them from the respective drop down lists.
