Maintaining Your CG-5 and Trouble-shootingLevel the instrument (using the tripod setupprocedures) to within -10 to + 10 arcseconds aboutboth axes.PRESSPRESSMEASURECLRF5Press the key. The Autogravnow automatically takes and records a reading onceevery 60 seconds (57 sec for each reading and threeseconds for calculation overhead).After 12 - 24 hours, press the F5 key.Output the data to a computer. For details on thisprocedure, please see Chapter 3, “Operating theCG-5 in the Field” and the “Dumping Data” topicthat starts on page 3-20.Below is a procedure for calculating the Driftconstant. The data could also be processed in aspreadsheet or other processing package.Reading the DataFrom the listing, take one reading (R1) at time T1close to the start of the recording period and anotherreading (R2) at time T2 from near the end of theperiod.Important:Do not use readings which are obviously noisy ordisturbed.From these values, calculate a new Drift Correction.DRIFT' =DRIFT +R2 – R1--------------------T2 – T15-14CG-5 Manual - part # 867700 Revision 2
Adjusting Instrument Parameterswhere:DRIFT is the Drift constant in the instrument during readings and (T2-T1) isin units of days.ExampleSelecting: T2 = 15:10:30Gives the corresponding readings:andTherefore,DRIFT = 0.000R2 - R1 = 0.034 mGalT1 = 14:56:27R2 = 3969.418R1 = 3969.382T2 - T1 = 0.23383 hrs =.00974 daysDRIFT' = -3.6949MaintenanceAdjusting the Drift CorrectionThe final step is to apply the calculated driftcorrection. To do this:PRESSF5Select the AUTOGRAV icon in the main SETUPscreen and press the F5 key. The system displays theAUTOGRAV PARAMETER setup screen.PRESSF1Press the F1 key to access thesecond AUTOGRAV PARAMETER setup screen.Press the up and down arrows to navigate to theDrift field.5-15CG-5 Manual - part # 867700 Revision 2
