3.3 SENSOR WIRING

3.3.1 General

The wiring label, which is shown in Figure 3-4, is a general purpose label. It has wiring infor- mation concerning other sensors, for example, contacting conductivity and pH, that can be used with the 54eA instrument platform. For the measurement of oxygen only terminal strip TB3 is used.

3.3.2 Wiring the Oxygen Sensor

Figure 3-5 shows how to wire the oxygen sen- sor to the analyzer.

Although it is not standard with the Model DO- 03/04, an optional quick disconnect (Variopol) sensor and cable are available. Figure 3-6 shows how to wire this sensor to the analyzer.
