Page 7: Fluoride Concentration Measurement
Fluoride concentration measurement Preparation 4.1.1 Press key to start connect F501 -fluoride ion electrode; the meter automatically switches to the fluoride concentration measurement mode. 4.1.2 Hold to change fluoride concentration unit from mg/l, ppm to pX, release the button after selection. 4.1.3 Activate the electrode in 19.00mg/L calibration solution for about 10-20 minutes (as long as the smiley face icon stays stably on the screen) before calibration and measurement. -
Page 8: Sample Measuring
Sample Measuring 4.3.1 Rinse the fluoride-ion electrode in distilled or deionized water and dap off excess water with clean tissue; soak into solution, stir gently and let it stand still; get the readings when measuring vaule is stable and stays on screen. 4.3.2 Hold to show Fluoride concentrations in different units, release after selection. -

4.5.2 The calibration solution can be easily polluted, especially for low concentration solution (0.19 mg/l). Please pay attention to avoid contamination otherwise a large measuring error will occur. Replace the solution after 4~5 times of use. 4.5.3 When test solution in the order from low-concentration to high-concentration, the electrode does not need to be rinsed, just shake off or dry the excess solutions with clean tissue. - Page 10 again, the LCD will show a blinking 7.00 pH, indicating the 1 point of calibration is completed; a stable pH value and a blinking C2 will be displayed, indicating the first point calibration has been finished and the meter enters the second point of calibration. 5.2.3.

Page 11: Sample Test
Sample Test Soak the pH electrode into the sample solution after rinsing and drying, hold the electrode still. Take the readings when the smiley face icon shows up and stays on screen (indicates a stable reading). pH isothermal measurement principle According to the theory of Isothermal measurements, the smaller the difference of the temperatures between test solution and the calibration solution, the higher the measuring accuracy is. - Page 12 (b) Press key to choose buffer solution series: ( Europe & U.S.A series) —1.68, 4.00, 7.00,10.01 and 12.45 pH (NIST series) — 1.68, 4.01, 6.86, 9.18 and 12.45 pH ( (China series) — 1.68, 4.00, 6.86, 9.18 and 12.46 pH (c) Press key to enter next parameter setting or press key to confirm and...
- Page 13 5.4.5. Temperature unit ℃/℉ setting (P4) (a) Short press key in mode P3 to enter mode P4, see picture (4-5). (b) Press key to choose temperature unit: ℃ or ℉. (c) Press key to enter into next parameter setting or press key to confirm and return to measuring mode.

Page 14: Special Notes
the pH measuring parameters have been restored to the factory default setting. Special Notes 5.5.1. The frequency that you need to calibrate your meter depends on the tested samples, performance of electrodes, and the requirement of the accuracy. For high-accuracy measurements (≤... - Page 15 After that, soak it in the KCL solution again for 6 hours. 5.5.6. An electrode be used for a long time, or measured solution which contains a polluting solute easily for the sensitive bulb, or a substance resulting in jam at the junction, the electrode will be getting passivated, its sensitivity will decrease and its response is getting slow, the reading are not correct.
