* Sensors have a BNC connector that the Model 3081 pH/ORP transmitter does not accept. Cut off the BNC and terminate
the coaxial cable as shown in Figure 3-23. Alternatively, use a BNC adapter (PN 9120531).
** Set the RTD jumper to the 3K position (see Section 2.2). Also, program the transmitter to recognize the 3K RTD (see
Section 8.5 for pH or 10.5 for ORP).
