Technical Report WRD92039 Viewed at 15:07:17 on 29/07/2010 Page 182 of 192. D5.4 EXAMPLE OF DATA SET CORRECTION AND RE-CALIBRATION : Use files : "SYOB-MHF.PRO" "SY-HJI-NOD. PRO" "BARO-TYP.PRO" "DATMAN" file of logged Head from a pump test observation bore; "DATMAN" file of Manual readings from a pump test observation bore; "DATMAN" file of Barometric Pressure . These files are from the "Syrimi" sub-directory of the Pump Test OB diskette. The Barometric data is used to correct the Logged data, and the corrected data is then to be recalibrated by the Manual data. A complication in this example is that the original calibration of the logged data is very poor - the logger input used was calibrated for a different probe. Before the data can be recaLLbrated it must be corrected for Barometric changes {B} however, this data is presumably calibrated properly so {B} must be recalibrated to the "poor" calibration, before it can be applied to the logged data, and the corrected data then recalibrated to the Manual readings. Read the 3 files above as sets {L},{Z} and {B}, and press S (to rescale plot). (il Convert Logged Head to DD (as per (2) of 1.1 above) Select the initial Head reading before DD started (LHO) say 10.02, and subtract it from {L} (Mark both ends of set, , ent, "10.02", ent); Nultiply (*) result by -Ii {L} is now Logged (uncorrected) DD (LDD above); S to rescale; Notice the large differences bebleen the Logged and Manu<~1 readings.
