The status LED will be amber in color during warm-up and will change to green when the unit is ready. The following operations will be completed in this warm-up sequence: Heat the sensor to operating temperature Perform the Power-On-Self-Test (POST) 90000003 R11 Page 8 of 21

WARNING: H2SCAN S N2 BACKGROUND ANALYZERS SHOULD NEVER BE OPERATED IN AN AIR OR OXYGEN BACKGROUND. 4.1 FOR N2 BACKGROUND ANALYZERS After warm-up, the analyzers should be run in a hydrogen concentration exceeding 5% by volume for at least an hour. Oxygen will readily adsorb on the HY-OPTIMA 700 Analyzer and can confound the hydrogen measurements. The analyzers can be exposed to oxygen for short periods of time without adverse effects if the unit is turned off. If the units are operated in oxygen or stored in air for longer than a week, the units hydrogen readings may be high due to oxygen adsorption on the sensor. Hydrogen exposure will then cause the readings to drift lower as adsorbed oxygen is slowly removed and the unit recovers to normal steady behavior. If this drift behavior is observed, the sensor should be conditioned by operating in a hydrogen concentration exceeding 5% until the readings are stable (< 0.05% fluctuation). The required hydrogen conditioning may vary from several hours to several days depending on the level of oxygen exposure. Higher hydrogen concentrations used during conditioning may accelerate the process. Once stable (< 0.05% fluctuation), the unit could be taken through calibration if needed. Step Description 1 Power units on in 5% H2/N2 by volume or greater 2 Operate the HY-OPTIMA 700 Analyzer in the 5% H2/N2 or greater gas for six hours or longer 3 Check to see if the sensor readings are accurate and stable over that time(< 0.05% fluctuation) 4 If the readings are not accurate and stable, condition the sensor in 5% H2/N2 or greater gas overnight and perform the calibration described later in this manual 4.2 FOR AIR BACKGROUND ANALYZERS The analyzer is designed to be exposed to air with no hydrogen most of the time. For optimal performance keep any hydrogen exposure to the sensor to less than one hour. If the hydrogen exposure exceeds this time, the sensor may need to be reconditioned by leaving it powered on in air for a few days. 4.3 SETTINGS Located on the front of the unit next to model number marking, a Status Indicator displays basic unit function as described below. Default amber and red Status Indicator LED settings are 1% and 2% hydrogen by volume, respectively. Status Normal operation / Hydrogen detected is below 1% hydrogen by volume Warm-up / Hydrogen detected between 1% and 2% hydrogen by volume Hydrogen detected above 2% hydrogen by volume / Unit fault detected Indicator Color GREEN AMBER RED The unit s operational and output settings have been configured at the manufacturer with settings specified at the time of purchase. Settings may be changed through the Serial port. 90000003 R11 Page 9 of 21

WARNING: IF SETTINGS ARE CHANGED FROM THOSE SET BY THE MANUFACTURER THEN IT IS THE USER S RESPONSIBILITY TO UNDERSTAND THE IMPLICATIONS TO THE CONNECTING EQUIPMENT MONITORING THE UNIT. 4.4 VISUAL STATUS INDICATOR Located on the front of the unit next to model number marking, the Status Indicator LED displays basic unit function as described below. Status Normal operation / Hydrogen Detected below R1 set point Warm-up / Hydrogen Detected above R1 and below R2 set points Hydrogen Detected above R2 set point/ Unit fault detected 5 OPTIMUM UNIT PERFORMANCE Indicator Color GREEN AMBER RED For maximizing the performance of the sensor, the following steps are recommended. Verify that all electrical connections are made as recommended. Switching the polarity can cause damage to the unit. Ensure that the DC power supply utilized is appropriate and does not have large peak-to-peak noise. Perform a Field calibration after the installation and conditioning steps described in the Start-up section are completed If a N2 background analyzer gets exposed to extended periods of no H2 (or some oxygen), condition the sensor as described in the Start-up section and follow-up with a Field calibration, if needed. If an air background analyzer gets exposed to extended periods of H2, condition the sensor as described in the Start-up section and follow-up with a Field calibration, if needed. The HY-OPTIMA 700 Analyzers are hydrogen specific and sensitive to only the hydrogen partial pressure in the gas stream. Since changes in total gas pressure will affect the hydrogen partial pressure, they will also affect the sensor readings. For instance, at one atmosphere pressure, a 50% H2/N2 mixture will be reported as 50% from the unit. At 1.1 atm, the reading will increase to 55% and two atms will result in a reading of 100%. In fact, the HY-OPTIMA 700 Analyzers are capable of measuring multiple atmospheres of hydrogen and readings above 100% H2 are interpreted as hydrogen pressures above one atmosphere. At the factory, the units are calibrated at one atmosphere pressure. Performing the Field calibration at the operating pressure will display the pressure corrected reading. For e.g. if the local atmospheric pressure is 0.97 atm, doing a Field calibration will correct for this. If the exhaust is to atmosphere, it is preferable to install a back-pressure regulator at the exhaust and set it to slightly above the atmosphere pressure (e.g. 1.01 ATM). This will eliminate any inaccuracy from pressure fluctuation. The same logic could be used to correct incoming and outgoing pressure fluctuations in a process steam. This should be done at installation prior to calibration. The accuracy of the gas bottle concentration will directly affect the measured accuracy by the units. During factory calibration, the units are calibrated with high accuracy gases (as high as +/- 0.02%). It is strongly recommended that the user perform calibration with similar high accuracy gases to maintain the highest accuracy. 6 ANALOG OUTPUT A custom analog output range can be selected. Standard analog output ranges which are listed below. The analog output the user selects is scaled to the user s hydrogen range of interest. All of this is initially set at the factory per customer specification at the time of order. Below is the table for standard analog output current and voltage ranges: 90000003 R11 Page 10 of 21

Analog Output Current Range (ma) Power-On Self Diagnostic (ma) Error (ma) 4 to 20mA 2mA 3mA 0 to 20 ma 0mA 20mA Analog Output Voltage Range (V) Power-On Self Diagnostic (V) Error (V) 0 to 5 0 5 1 to 5 0.5 0 0 to 4 5 4.5 0.5 to 4.5 0 5 WARNING: THE USER CANNOT CHANGE FROM A CURRENT RANGE TO A VOLTAGE RANGE OR FROM A VOLTAGE RANGE TO A CURRENT RANGE OUT IN THE FIELD. THIS REQUIRES A FACTORY MODIFICATION. 7 SERIAL COMMUNICATION The user can monitor and control the unit via serial communication via the serial interface. 7.1 SOFTWARE Software that communicates over the serial port is typically called a terminal emulator. Any two-way terminal emulators (HyperTerminal, Telnet, etc.) or purpose-built software (using LabView, Visual Basic, C++, etc.) can be used to establish serial communication with the unit. XP and previous versions of Windows came with a terminal emulator called Hyper Terminal. Newer versions of Windows do not. These versions require installing a third-party program. There are many inexpensive or free programs available. FoxTerm, a free program, is used extensively by H2scan. 7.2 CONNECTION Connect the sensor to the serial port, using whatever adapters are required. If a USB adapter is used, install the driver according to its instructions. In Windows, look at the ports using the Device Manger. A built-in port will be COM1. The port assigned to the USB adapter could have any number, but it will be called something like USB Serial Port (COM7) or I-756X (COM3). Below is an example. Note the port number that Windows has assigned. 7.3 FORMAT AND SETTINGS RS232 (RS422 optional) 19200 Baud 8 bit data 1 stop bit 90000003 R11 Page 11 of 21

8 MAINTENANCE 8.1 CLEANING If the unit is exposed to process streams containing debris, condensates or other material that may collect over the sensor tip then the unit should be removed from the stream periodically and the tip cleaned by a gentle wiping with a clean lint-free cloth or paper. 9 CALIBRATION Calibrations do not cause any wear on the sensor and can be accomplished as often as desired. Analog outputs can be monitored. 9.1 FACTORY CALIBRATION Contact H2scan to make arrangements for a comprehensive Factory Calibration using high accuracy gases by H2scan s factory trained technicians; optional NIST traceable certificate available upon request. An annual Factory Calibration is advisable to optimize performance. 9.2 FIELD CALIBRATION In the event the Field Calibration procedure seems to not be effective, H2scan recommends the unit be shipped back to the factory for a comprehensive evaluation and Factory Calibration. 10 FIELD CALIBRATION 10.1 CALIBRATION INTERVAL H2scan recommends that the system calibration be carried out every 90 days. 10.2 GASES Calibration requires the availability of one or two certified known gases at values specific to the application. One gas will correct any offset error while two gasses will also correct any gain error. It is recommended to use two gasses to obtain superior calibration accuracy. DO NOT use 0% H2 as the lower calibration gas. Instead use hydrogen concentration that is slightly lower than the expected lowest hydrogen concentration (e.g. if 1% is the expected lowest H2 concentration, then use 0.5% H2 as the lower calibration gas. For the second calibration gas use a concentration that is slightly higher than the expected maximum H2 concentration. The recommended flow rate required is 0.5 ± 0.2 slpm. Calibrate the sensor in the proper background gas. For a unit calibrated in hydrogen in an inert gas background, carry out calibration in hydrogen in an inert background. For a unit calibrated in hydrogen in an air gas background, carry out calibration in hydrogen in an air background. Custom Field Calibration Kits are available from H2scan. 10.3 GAS CONNECTION Gases are applied to the unit through user s piping. 10.4 PROCEDURE During the Field Calibration process any previously completed Field Calibrations are cancelled. As a result, during the routine the unit may display a hydrogen concentration that is different from the applied gas concentration. This is normal. Once the procedure is completed, the readings will be corrected to display the right concentrations for all subsequent exposures. NOTE: Field calibration must ALWAYS be done at the customer s process pressure. 90000003 R11 Page 16 of 21
