139 GSM19 Series Magnetometers - Version 7
APPENDIX I: PROGRAMMABLE BASE OPTION
The programmable base feature allows full control over the base surveys. It is particularly useful for remote or unattended base stations.
By programming or scheduling the base, you can determine when the surveys begin and end hours, days or years in advance. This result in a more efficient use of batteries or other available power sources, and also avoids storing in memory hours or days-worth of unwanted data. Because a new file is created every time a base survey starts, each schedule has its own file.
I.1 SETTING UP THE PROGRAMMABLE BASE STATION OPTION
From the Main Menu, press A-survey to access the Survey Menu and then, with survey mode highlighted, press C-change.
NOTE:
If GPS synchronization is required make sure the GPS is enabled.
