<strong>Instruction</strong> Manual pH 1100/ 210010.2.7 Stability Setup Program P1.5Use this program to turn on or off the pH stability indicator and toset level of stability (low, medium or high).Stability definitionsHigh 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 accuracy1. Enter pH/Temperature setup mode as described in steps 1-4 in 10.2.1 Entering pH/temperature setup mode (page 30).2. Use Δ/MI to scroll to program Stability Setup: P1.5. SeeFigure 94.3. Press ENTER to enter program Stability Setup: P1.5.4. Press >/CAL key to toggle between pH Stable Criteria: Onand Off. The selection will flash. See Figure 95.5. Press ENTER to confirm selection.• If you selected On, continue to step 6.• If you select Off, pressing ENTER returns to the setupmode.Stability Setup : P1.5Pr es s ENT. t o Sel ec tFigure 94pH Stable CriteriaOn Of fFigure 95Degree of StabilityLow Medium HighFigure 96Press Δ/MI to continue to the next setup program, or press∇/MR to go to the previous program.

<strong>Instruction</strong> Manual pH 1100/ 210010.2.8 View pH calibration data setup program P1.6Use this program to view the following:• Last pH calibration date/time• pH buffer set selected• pH calibration temperature and temperature compensation• pH offset value• pH slopes (from acid to alkaline)1. Enter pH/Temperature setup mode as described in steps 1-4in 10.2.1 Entering pH/temperature setup mode (page 30).2. Use Δ/MI to scroll to program pH Cal Data: P1.6. See Figure97.3. Press ENTER to enter program pH Cal Data: P1.6. The firstscreen in pH Cal Data: P1.6 is the pH Cal Date/Time. SeeFigure 98.4. Press ENTER to proceed to the second screen. This screenshows current buffer set and calibration points. See Figure 99.5. Press ENTER to proceed to the third screen. This screenshows calibration temperature and temperature compensationmode. See Figure 100.6. Press ENTER to proceed to the fourth screen. This screenshows current pH offset value in mV.

Press ENTER to proceed to the fifth screen. This screenshows current acid slope 1 and 2. See Figure 102.8. Press ENTER to proceed to the sixth screen. This screenshows current acid slope 2 and alkaline slope 1.—See Figure103.pH Of f set =0.2 mVFigure 1019. Press ENTER to proceed to the seventh screen. This screenshows current alkaline slope 1 and 2.—See Figure 104.10. Press ENTER to return to the setup mode. Press Δ/MI tocontinue to the next setup program, or press ∇/MR to go to theprevious program. Press EXIT to return to the pHmeasurement mode.Note: While viewing calibration data, you may press EXITat any time to return to the setup mode.Acid Slope1 = 100.0 %Acid Slope2 = 99.7 %Figure 102Acid Slope2 = 99.7 %Alk.
