    8.3.2 Setup Product The SP-910 will display PTSA in ppb unit as the default in the PTSA measurement. A product name can be assigned to allow the SP-910 to display the product name instead of PTSA. The product/PTSA ratio can be set up according to Figure 25. For products containing 0.1% PTSA, the ratio is 1000, which means that 100 ppb PTSA equals to 100 ppm product.

The SP-910 will keep reading ST-500 every 4 seconds to verify if the calibration is successful. Please note that it takes about a minute for the ST-500 to approach to the calibrated reading.

  • Page 34: Maintenance

    Use a soft cloth or lint free paper tissue to clean the sample vial compartment periodically. Remove debris, scale, and deposit promptly. Although The SP-910 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.

  • Page 35: Troubleshooting

    If an unspecific error occurs or the SP-910 cannot be turned on, reboot the instrument by taking a battery out of the battery holder and re-install the battery. If the SP-910 has been idle for more than two months and cannot be turned on, replace all four batteries with four new AA alkaline batteries.
