CAUTION Do not setup or operate the Oxygen Analyzer without a complete understanding of the instructions in this manual. Do not connect this Analyzer to a power source until all signal and plumbing connections are made. CAUTION This analyzer must be operated in a manner consistent with its intended use and as specified in this manual. DANGER The electrolyte is a caustic solution. Review the Material Safety Data Sheet (MSDS) before handling the electrolyte solution. The sensor is shipped dry and must be charged with electrolyte before it is operated. CAUTION Over-pressurizing the sensor can result...

EMI DISCLAIMER This Analyzer generates and uses small amounts of radio frequency energy. There is no guarantee that interference to radio or television signals will not occur in a particular installation. If interference is experienced, turn-off the analyzer. If the interference disappears, try one or more of the following methods to correct the problem:  Reorient the receiving antenna.  Move the instrument with respect to the receiver.  Place the analyzer and receiver on different AC circuits.

3 Specifications Range of Operation: 0-10ppm Lowest Detection Level (LDL): 0.2 ppb @ Constant Conditions Resolution (Smallest Detectable Change): 0.1 ppb Calibrated Accuracy: ±3 percent of reading or ±0.5 ppb (whichever is greater) @ Constant Conditions Response Time: Typically less than 15 seconds to read 90 percent of a step change. The equilibrium time is dependent on specific conditions. Upset Recovery Time: Typically less than 15 minutes from a high ppm upset to within 10 ppb of the previous stable reading. Ambient Operating Temperature: 0° C to 45° C (32° F to 110° F) Analog Output Range:...

4 Installation and Setup This procedure describes installation of the analyzer without options and with the voltage output set to 0-10 VDC. Options may affect the setup procedure described in this section. If your analyzer is equipped with options, refer to the appropriate section to determine changes to the setup. NOTE The screens shown in this manual have values that may not match the actual values displayed during your setup. Figure 2: Major Internal Components

4.1 Adding Electrolyte DANGER The electrolyte is a caustic solution. Review the Material Safety Data Sheet (MSDS) before handling the electrolyte solution. NOTE The sensor is shipped dry and must be charged with electrolyte before it is operated. NOTE Use only Hummingbird Brand E-Lectrolyte Gold in the Platinum Series NanoTrace Oxygen Analyzer. (gold sensor cap) Failure to do so will void warranty. Install one bottle only. NOTE Do not apply power before adding electrolyte and thoroughly purging sample line. 4.1.1 Adding Electrolyte Procedure Follow this procedure to add electrolyte: 1. Remove...
