Stability definitions High stability: reading is stabilized quickly, but reading is less accurate. Medium stability: reading stability is averaged between high and low stability. Low stability: reading is stabilized slowly, but guarantees high accuracy 1. Enter pH/Temperature setup mode as described in steps 14 in 10. 2. 1 Entering pH/temperature setup mode (page 30).

Stability Setup : P1. 5 Press ENT. [. . . ] The most common standard buffers are pH 4. 01, pH 7. 00 and pH 10. 01. For 1-point calibration, use a standard buffer of pH 7. 00 or 6. 86, or a standard or custom buffer whose pH value is close to that of the sample. Use 2-point calibration when you know the sample is acidic (low pH) or basic (high pH). For example: in acidic samples, use standard buffers such as pH 7. 00 and pH 4. 01; in basic samples, use standards such as pH 7. 00 and pH 10. 01. [. . . ]
