Maintenance Best Practices and Quick Tips
For greatly increased working life and ease of use of the SP-380 follow the list of maintenance best practices
and quick tips below:
• Rinse the sample cell at least three times with the desired solution before turning on.
• After a successful calibration, the unit does not automatically return to the measurement mode. If
Exit is held down too long the unit will power down rather than returning to the measurement mode.
• After returning to measurement mode after calibration, rinse several times with the first sample. The
unit will continue to read the sample values without any further key presses if it has not powered off.
If there are no key presses for 20 seconds the screen will darken, and after another 20 seconds without
key activity will power down. The press of any key while the screen is dark will reset the timer and
the screen will re-light. (This press will not step along the calibration process; the next press needed
will still be required in the sequence).
• Always rinse the unit with clean water after use and dry by clean tissue or paper towel.

Methods to Cleaning the SP-380
A light deposit on quartz glass inside the sample cell can be cleaned by a Q-tip. Aged heavy deposition,
especially iron oxide deposited, can be removed using a cleaning solution that is capable of removing iron,
such as the Pyxis Handheld Device Cleaning Solution Kit (P/N: SER-02) available from Pyxis online E-Store

To clean the SP-380 pour cleaning solution into the sample cell for 10 minutes. Rinse the sample cell with
distilled water and use the Cleanliness Check (see the
section) to confirm
that the SP-380 is clean. Repeat the process as needed until the Cleanliness Check shows
Clean
