  • Page 24: Two-Vial Methods

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

  • Page 25: Advanced Methods

    The SP-910 must be zeroed using the prepared blank before the last timing step. Thus, the last timer button will not be selectable until the 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.
