7 Maintenance
Use a soft cloth or lint free paper tissue to clean the sample vial compartment
periodically. Remove debris, scale, and deposit promptly.
Although Pyxis SP-900 is protected from water damage, it is a good practice to avoid
water entering the sample vial compartment and becoming trapping underneath the
navigational control pad. Deposits left behind when the water is evaporated could
affect Pyxis performance.
Pyxis SP-900 should be stored in the temperature range of 0 to 140 °F (-18 to 60 °C )
and relative humidity less than 85% at 106 °F (41 °C ). Do not leave the Pyxis SP-900
in a parked vehicle. The temperature inside a parked vehicle can reach above 150 °F
in summer and -20 °F in winter. Exposing the Pyxis SP-900 to extreme temperature or
humidity will cause a gradual decay in performance of fluorescence measurements
and require more frequent calibrations.
During storage and transportation, do not leave a sample vial in the sample vial
compartment. Close the lid of the sample vial compartment during storage and
transportation.
Replace batteries when the Pyxis SP-900 displays a warning message indicating LOW
BATTERY voltage. Remove batteries from Pyxis SP-900 battery compartment if Pyxis
SP-900 is going to be placed in storage for a long period time.
When the Pyxis SP-900 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.
