OPERATION MANUAL - Scintrex

Optimizing your Field OperationsAfter a 12-hour period, the instrument operates properly, except that thelong-term drift will not be stable. Good results can usually be obtained afterthe 12-hour period, if you follow these steps:1. Design the field survey such that there are frequent repeat readings at basestation(s) and correct for drift in the data reduction. Do not attempt toadjust the Drift constant in the CG-5 software yet. For the first day ofsurveying, it is advisable to re-occupy base stations approximately onceevery two hours. On the second day, once every 4 hours is probably sufficient.2. At the end of the second day’s work, adjust the Drift Correction. After this,the instrument can be operated normally.4-6CG-5 Manual - part # 867700 Revision 2
