    Figure 10 Single Timer Method 5.4 Single-Vial Procedure 1. Place the sample vial filled with the water sample in the Pyxis SP-910 sample vial compartment and press the ZERO button. Pyxis SP-910will display the page shown in Figure 11.

  • Page 22: Multiple Timing Steps

    The following procedure is typical for two-vial methods: 1. Place the prepared blank into the Pyxis SP-910 sample vial compartment and press the ZERO button to zero the instrument.

  • Page 23: Advanced Methods

    In order to show the concentration-time curve as shown in Figure 9during the last timing step, Pyxis SP-910must be zeroed using the prepared blank before the last timing step. Thus, the last timer button will not be selectable until Pyxis SP-910 has been zeroed using the prepared blank. Multi-timing step Hach® methods require zeroing the colorimeter using the prepared blank after the last timing step is completed.
