Typical battery life lasts for 10,000 measurements or 10 months. When the battery capacity is critically low, the SP-200 will display a "LOW BATTERY" warning for 5 seconds and then automatically turn off. *NOTE* Do not use rechargeable nickel cadmium (NiCad) or lithium batteries. Replace the batteries to resume operation of the SP-200 after the battery warning. The SP-200 will automatically turn on in the measurement mode after new batteries are installation. The SP-200 battery compartment, shown in Figure ??, is on the back side of the instrument. Batteries are held in place by a cover secured with two Phillips-head screws. Figure 1. The SP-200 battery compartment Install batteries using the following steps: 1. Remove the battery compartment cover by loosening the two screws. 2. Remove old batteries and dispose of them properly. 3. Following the positive and negative terminal signs in the compartment bottom, snap four new AA alkaline batteries firmly into the battery holder. 4. Replace the battery compartment cover and ensure that the sealing O-ring is lying flat on the battery holder. 5. Fasten the two screws. *NOTE* Failure to properly seat the O-ring may result in water damage to the SP-200. SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 5 5 Instrument Overview Figure 2. 5.1 Control Keys The SP-200 has three control keys, as shown in Figure 2. The left ( ), right ( ), and ok ( ) keys are used to launch actions indicated on the LCD display directly above the keys. The labels above the keys indicate the function associated with each key and functions can be changed in different operation modes. 5.2 Main Module On/Off To turn on the SP-200: Press momentarily and release. To turn off the SP-200: Press and hold for about three seconds. Release when the LCD display turns off. The SP-200 turns itself off after 60 seconds without user interaction detected. This is done to conserve battery life. *NOTE* This auto-time off setting may be customized by the user as desired through the uPyxis® Mobile or Desktop App. SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 6 6 Measurement 6.1 Colorimetric Methods A wide range of colorimetric methods is supported by the SP-200 analyzer and the number of them keeps increasing with continuous development of Pyxis.

The message "Low point calibration succeeded" will appear on the display (Figure 12). 9. Press to exit. Figure 10. Figure 11. Figure 12. SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 10 7.3 Slope Calibration Each method has been calibrated prior to shipping, there is no need to calibrate unless a calibration check indicates that the method needs a calibration. The following steps are used to carry out a slope calibration: 1. Complete a measurement with the desired method. 2. Press Cal/Sys ( ) as needed to highlight Slope-C. 3. Press OK ( ) to launch the calibration screen (Figure 13). 4. Fill a sample vial with a solution with known concentration and place it in the sample vial compartment of the SP-200. *NOTE* For best results, the know concentration should be less maximum concentra- tion of the method. See the Supported Colorimetric Methods table for concentration ranges for each method. 5. Use « ( ) and ( ) to adjust the concentration value to match the known concentration of the solution. 6. Press Calib ( in Figure 14. ) to continue with the entered concentration value. The display updates as shown 7. Press OK ( ) to start the slope calibration. 8. The message "High point calibration succeeded" will appear on the display (Figure 15). 9. Press to exit. Figure 13. Figure 14. Figure 15. SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 11 7.4 Restore Factory Default Values Each method can be restored to the factory default intercept and slope values, individually. The following steps are used to carry out a factory default of the desired method's intercept and slope values: 1. Complete a measurement with the desired method. 2. Press Cal/Sys ( ) as needed to highlight Default. 3. Press OK ( ). The display updates as shown in Figure 16. 4. Press OK ( ) to start the factory default of the desired method. 5. The message "Restore data succeeded" will appear on the display (Figure 17). Figure 16. Figure 17.

Figure 31. SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 22 11 Device Maintenance and Precaution 11.1 Maintenance Best Practices and Quick Tips For greatly increased working life and ease of use of the SP-200 follow the list of maintenance best practices and quick tips below: · Use a soft cloth or lint free paper tissue to clean the sample vial compartment periodically. Remove debris, scale, and deposit promptly. · Although the SP-200 is protected from water damage, it is a good practice to avoid water entering the sample vial compartment. Deposits left behind when the water is evaporated could affect performance. · During storage and transportation, do not leave a sample vial in the sample vial compartment. · Replace batteries when the SP-200 displays a warning message indicating LOW BATTERY voltage. Remove batteries from the SP-200 battery compartment if the SP-200 is going to be placed in storage for a long period time. · When the SP-200 is shipped, a desiccant pack is included in the desiccant compartment underneath the cover of the battery compartment. It is recommended that a new desiccant pack is replaced each time the batteries are replaced. 11.2 Storage The SP-200 should be stored in the temperature range of 0140 °F (-1860 °C) and relative humidity less than 85% at 106 °F (41 °C). Do not leave the SP-200 in a parked vehicle as the temperature inside can reach above 150 °F in summer and -20 °F in winter. Remove batteries from the SP-200 battery compartment when in storage for a long period time. Do not leave a sample vial in the sample vial compartment. 12 Contact Us Pyxis Lab, Inc 1729 Majestic Dr. Suite 5 Lafayette, CO 80026 USA www.pyxis-lab.com Phone: +1 (866) 203-8397 Email: service@pyxis-lab.com SP-200 User Manual service@pyxis-lab.com | +1 (866) 203-8397 23
