REMOVE BNC AND TERMINATE COAXIAL CABLE BEFORE WIRING SENSOR TO TRANSMITTER. SEE FIGURE
FIGURE 3-6. Wire functions for Models 397-50, 397-54, 396-50,
396-54, 396R-50-60, 396R-54-60, 389-02-50, and 389-02-54
before removing BNC and terminating cable.
IF USING A BNC ADAPTER, THE RED WIRE IS MV OR pH IN AND THE BLACK WIRE IS REFERENCE IN. TO PREVENT SHORT CIRCUITS TO THE TRANSMITTER HOUSING, INSULATE THE BNC WITH BY WRAPPING IT WITH ELECTRICAL TAPE.
