Warranty Service
Damaged or dysfunctional instruments may be returned to Pyxis for repair or replacement. In some instances,
replacement instruments may be available for short duration loan or lease.
Pyxis warrants that any labor services provided shall conform to the reasonable standards of technical
competency and performance effective at the time of delivery. All service interventions are to be reviewed and
authorized as correct and complete at the completion of the service by a customer representative, or
designate. Pyxis warrants these services for 30 days after the authorization and will correct any qualifying
deficiency in labor provided that the labor service deficiency is exactly related to the originating event. No
other remedy, other than the provision of labor services, may be applicable.
Repair components (parts and materials), but not consumables, provided in the course of a repair, or
purchased individually, are warranted for 90 days ex-works for materials and workmanship. In no event will the
incorporation of a warranted repair component into an instrument extend the whole instrument’s warranty
beyond its original term.
Shipping
A Repair Authorization Number (RA) must be obtained from the Technical Support ([e-mail])
before any product can be returned to the factory. Pyxis will pay freight charges to ship replacement or

1.2 Pyxis SP-380P Major Features
The Pyxis SP-380P analyzer measures the concentration of fluorescent polymer or PTSA of
a water sample. Main features include:
•The SP-380P is pre-calibrated for measuring fluorescent polymer in the range of 0
to 20 ppm or PTSA in the range of 0 to 500 ppb. The fluorescent polymer or PTSA
measurement is automatically compensated for sample color and turbidity
interference.
•Fluorescent polymer can be calibrated with using three standards (0,10, and 20
ppm) through a user-friendly menu-driven procedure. Similarly, PTSA can also use
three calibrators (0,100 and 200 ppb) for calibration.
•No sample cuvette is required and as such variations associated with the cuvette
are eliminated.
•Large color graphic screen that can be read in direct sunlight.
1.3 Unpacking the Instrument
Remove the instrument and accessories from the shipping container and inspect each item
for any damage that may have occurred during shipping. Verify that all items listed on the
packing slip are included. If any items are missing or damaged, please contact Pyxis
Customer Service at [email protected]om.

1.6 Structure Description
The structure description is shown in Figure 1.
Figure 1: SP-380P Structure Description
2Start Pyxis SP-380P
2.1 Battery Installation
The SP-380P is powered by 4 AA alkaline batteries. Do not use rechargeable nickel cadmium
(NiCad) or lithium batteries. The 4 AA alkaline batteries will last sufficient for about 3000
measurements. When the battery capacity is critically low, the SP-380P will display a LOW
BATTERY warning for 5 seconds and then automatically turn off.

5
Replace the battery to resume operation of the SP-380P after the battery warning. The SP-
380P will automatically turn on in the measurement mode after new battery installation.
The SP-380P battery compartment, shown in Figure 2 is on the back side of the instrument.
Install battery as follows:
•Remove the battery compartment cover by loosening two screws.
•Make sure that snap the battery firmly into the battery holder.
•Replace the battery compartment cover, making sure that the sealing O-ring is lying flat
on the battery compartment. To prevent the SP-380P from accidently being turned on
due to vibration, please firmly tighten the two screws. The 4 AA alkaline batteries will
last for about 3000 measurements. When the battery capacity is critically low, the SP-
380P will display a LOW BATTERY warning for 5 seconds and then automatically turn off.

2.2 Description of the Control Keys
The SP-380P has three keys as shown in Figure 3 The left (<), right (>) and OK keys are used
to launch an action indicated on the screen directly above the keys. Please note that the
screen is not a touch screen. The labels above the keys indicate the function associated with
the keys and can change according to the screen modes.

2.3 Turning On/Off Pyxis SP-380P
To turn on the SP-380P, press OK momentarily and release.
To turn off the SP-380P, press and hold the OK key. Release the OK key when the LCD display
turns off (after about 3 seconds). The SP-380P will turn itself off after 60 seconds without
user interaction through the keys.
