Getting StartedA - ground levelB - positive input of the supply voltage +24 to 35 V; this input is connected inparallel to the centre pin of the coaxial TNC power connector on the samepanelC - Larmor output signal, TTL compatible square voltage signal at LarmorfrequencyD - TTL compatible input: high level or open for operation in the southernoperating hemisphere, low level or connected to pin A for operation in thenorthern hemisphere. This input is effective only if the Hemisphere Controlswitch is in the Remote (R) position.1-10CS-3 Manual - part # 762701 Revision 2.0
2 Operating theCS-3 in theFieldBy now you have familiarized yourself with your CS-3. This chapter reviewsthe basic steps required to carry out a survey. They include the following:• setting up the CS-3• mounting the CS-3• powering up• obtaining the Larmor frequency• setting the operating hemisphere• operating in the presence of spurious magnetic fieldsOperations2-1CS-3 Manual - part # 762701 Revision 2.0
