Select Part Code from the drop down list which displays the related parts for the selected Station No. and Instrument Code. Select Parameter Code from the drop down list which displays the related parameters for the selected Station No., Instrument Code and Part Code.

Select % Bias Based On whether Tolerance or Process Variation.

Study Date, End Date (i.e. the date when the last reading was taken) and % Bias for the Station No, Instrument Code, Part Code and Parameter Code are displayed in the grid. The calculated value of % Bias is based on the selection of Process Variation or Tolerance options provided on the screen. If the related value for Process Variation or Tolerance has not been entered, a dash character ("—") is displayed in the % Bias column.
