After new battery installation, Pyxis SP-380 will be automatically turned on to the measurement mode. The Pyxis SP-380 battery compartment, shown in Figure 2, is on the back side of the instrument. Install batteries as followings: 1. Remove the battery compartment cover by loosening four screws. -
Page 8: Description Of The Navigational Control Keys
2.2 Description of the Navigational Control Keys The Pyxis SP-380 has three keys as shown in Figure 3. The left (<), right (>) and OK keys are used to launch an action indicated on the screen right above the keys. The action associated with each key could be different in different operation modes. -

2.3 Turning On/Off Pyxis SP-380 To turn on SP-380, press and hold on the OK key for 3 seconds, and release the OK key when the LCD is lit. To turn off SP-380, press and hold on the OK key for 3 seconds, and release the OK key when the LCD is off. - Page 10 3) A Screen similar to Figure 4 appears. The unit is actively reading and displaying both PTSA and fluorescein. The values will be very low if DI water is used; PTSA and fluorescein should be near zero. A low non-zero value (e.g. 0.2 or 0.4, etc.) is not problematic.

on OK or the other keys will keep the timer going, giving you time to add the next one. To ensure accurate results and avoid sample carry-over/contamination, rinse at least twice with the next sample before closing light shield (it’s smart to include rinsing the inside surface of the light shield.) 4) Always rinse the unit with clean water after use and dry by clean tissue or paper towel. - Page 14 MEASUREMENT FLUORESCEIN CALIBRATION Insert DI Solution √ Click Zero Button Insert ppb Solution Click Slope Button Press cycle to choose solution Cycle Slope Exit Figure 9 6) Rinse the sample cell out thoroughly (twice) with the 50 ppb fluorescein standard and with the measurement cell near full, close the light shield.
- Page 15 9) Press the Continue labeled key (>) to continue middle range fluorescein calibration, the screen will also update to show the second Slope step, as in Figure 11. The possible fluorescein selection is displayed in red. The default is 250 ppb. If middle range and high range fluorescein calibration are not required, press the Exit labeled key (OK) any keys to exit.
