molbloc serial numbers are saved to the data file and are available in the COMPASS Report Editor to have in the calibration report. However the calibration due dates of the molblocs is not in the data file. Use this test macro to save the molbloc SN and calibration due date to StringData3 for each test point in the data file. Note that the calibration due date is not read but the calibration date is. This macro adds 365 days to that. Edit this number if you use a different calibration interval. See the COMPASS Help file to learn how to add a macro to a COMPASS and to a test.
