ABSTRACT:
A method for a seismic data acquisition system (FIG. 1) for determining whether a geophone circuit break is in a seismic cable conductor pair (22) or in a takeout conductor pair (26). A resistor (32, 32A) is positioned across the takeout conductor pair (26) for a geophone group (20). An impedance measuring device (30) determines if the break is in the seismic cable conductor pair (22) by measuring infinity for an open circuit, or by measuring the impedance of the resistor (32, 32A) if the break is in the takeout conductor pair (26).
