Page 11: Installation
4 Installation 4.1 Battery Installation The SP-208 is powered by 4 AA alkaline batteries. The 4 AA alkaline batteries will last sufficient for approximately 10,000 measurements. When the battery capacity is critically low, the SP-208 will display a LOW BATTERY warning for 5 seconds and then automatically turn off. -
Page 12: Ph/Orp Module Installation
Order a replacement pH/ORP module (P/N: 50315) from Pyxis at order@pyxis-lab.com. If the module is turned on for 20 minutes a day, the module battery can last for about a year. The module indicator light will flash red if the module battery is low. Each replacement pH/ORP module will be shipped with a COC (Certificate of Calibration). -
Page 13: Ph/Orp Module Battery Installation
4.4 pH/ORP Module Battery Installation The new pH/ORP module has a lithium thionyl chloride battery (3.7V-ER14250) installed. When the battery capacity is critically low and the main module displays a LOW BATTERY warning, replace the ER14250 battery. Use the following procedure to install a new battery: Unsnap the pH/ORP module from the top of the main module. -

6 Measurement 6.1 Switch Measurement Mode The SP-208 only has one measurement mode when it leaves Pyxis factory (i.e., DPD free and total Chlorine mode). However, the measurement mode of SP-208 can be expanded with the purchase of a pH&ORP module. *Note* The pH&ORP mode is disabled by default, refer to section 8.0... -

6.3 pH/ORP Measurement 6.3.1 Measurement Procedure *Precondition* when first using pH&ORP module, please enable and pair the pH/ORP module, refer to 8.0 section section. Once completed, follow the steps below for pH&ORP measurements Press pH/ORP ( ) to switch to the pH/ORP measurement mode. This will automatically power on the pH/ORP module. -
Page 19: Erroneous Values
6.3.2 Erroneous Values An erroneous pH value could be obtained if the module has been stored dry without the protection of pH/ORP Storage Solution for a long period of time. In this case, please fill the module cell with pH/ORP Storage Solution to wet the electrode and allow it to soak for 30 minutes before use. -
Page 20: Orp Measurement Principle
6.3.4 ORP Measurement Principle The SP-208 pH/ORP module measures the sample ORP with the platinum electrode and the Ag/AgCl reference electrode in the pH/ORP cell. The pH measurement and the ORP measurement share the same reference electrode. Reporting an ORP value without specifying the reference scale has no meaning. -

7 Calibration Free & Total Chlorine Calibration The 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 calibrate a method: 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. - Page 22 Figure 16 Figure 17...

Page 23: Ph Calibration
pH Calibration The SP-208 is designed to provide a flexible calibration procedure. The user can start with the one-point pH7 calibration and progressively add a two- and three-point calibration with the pH4 and pH10 buffers. This allows the user to choose a procedure based on the need of measurement accuracy and the target pH range. -
Page 24: One-Point Calibration
7.2.1 One-Point Calibration Rinse the pH/ORP sample cell three times with the pH7 buffer. Fill the sample cell with the pH7 buffer. Allow 5–10 seconds for the pH measurement to stabilize and the padlock ( ) to appear. Press pH7 ( ) to start a one-point calibration. -
Page 25: Three-Point Calibration
7.2.3 Three-Point Calibration Use the remaining buffer (either the pH4 or pH10) for a three-point calibration. Rinse the pH/ORP sample cell three times with the remaining buffer. Fill the sample cell with the remaining buffer. Allow 5–10 seconds for the pH measurement to stabilize and the padlock ( ) to appear. -
Page 26: Orp Calibration
ORP Calibration The ORP scale of the SP-208 depends on the ORP scale of the calibration standard. For example, if the value of 220 mV for the common Zobell’s standard at 25 °C is entered in the above calibration, the ORP value reported by the SP-208 after calibration is referenced to the Ag/AgCl(3M KCl) scale. - Page 27 7. Press OK ( ) to launch the ORP CALIBRATION screen (Figure 23). 8. Use + ( ) and - ( ) to adjust the ORP value to match the ORP standard used. 9. Press Calib ( ). The message “Calibration Success” will appear on the display (Figure 24).
