3.2.3.4 Coil separation
Enter the separation distance (in cm) that was measured when installing the triads ( section 2.2.2.2 ).
The accuracy of the survey depends on this parameter being entered correctly.
3.2.3.5 Coil calibration constants
During manufacture of the 350 system care is taken to match the coils and their pre-amplifiers to each
other. However, there will inevitably be some small residual differences between individual sensing
coils.
Each of the sensing coils supplied has an identification plate that includes a calibration constant. The
350 system requires this information so that it can compensate for the residual differences between
sensing coils.
During the coil installation process ( section 2.3.4 ) you should have recorded the calibration constants
for each of the six coils, together with their serial numbers and locations. The Configuration Log form in
Appendix E includes a suitable space for you to record these details.
The system is supplied with the coil triads already assembled, and with DeepView configured with the
relevant calibration details. Use the System Parameters window to check the calibration values are
correctly configured.
If you exchange a sensing coil for any reason, enter the new five digit value for the calibration constant
in the relevant box on the screen.
Do not change any other values .
Each of the six calibration constants will be different, and you must enter them carefully. The numbers
include an error-checking element that helps to ensure valid data entry.
