WIRING
REMOVE BNC AND TERMINATE COAXIALCABLE BEFORE WIRING SENSOR TO
TRANSMITTER. SEE FIGURE 3-23. ALTERNATIVELY, USE ABNC ADAPTER (PN
9120531) OR ORDER MODEL OPTION -62 (SENSOR WITH BNC REMOVED AND
TERMINATIONS COMPATIBLE WITH 3081 pH/ORP). IF USING ABNC 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 BYWRAPPING IT WITH ELECTRICALTAPE.
