[. . . ] · After the first calibration point is confirmed, immerse the pH electrode with the Potential Matching Pin into the second buffer (e. g. pH 4. 01) and stir gently Note Note If you are not going to perform a three-point calibration, it is recommendable to use pH 4. 01 buffer if you are going to measure acid samples, or use pH 10. 01 buffer for alkaline samples. The electrode should be submerged approximately 4 cm (1½") in the solution. The temperature probe should be located as close as possible to the pH electrode. · Select the 2nd buffer value on the secondary display by pressing or (e. g. pH 4. 01). · Only when the reading is stable the probe indicator " " will stop flashing (after about 30 seconds) and the "CFM" indicator will blink. · Press CFM to confirm the calibration; if the reading is close to the selected buffer, the meter stores the reading, adjusting the slope point and the secondary LCD will display the expected third buffer value. If the reading is not close to the selected buffer, "WRONG " will blink. BUF · Press CAL and the calibration process is ended with the offset and the 1st slope of the meter calibrated. 30 Three-point Calibration · Proceed as described above but do not quit calibration by pressing CAL. Note The meter will automatically skip the two buffers that were used to prevent errors. · After the second calibration point is confirmed, immerse the pH electrode and the Potential Matching Pin into the third buffer solution (e. g. pH 10. 01) and stir gently. Note The electrode should be submerged approximately 4 cm (1½") in the solution. The temperature probe should be located as close as possible to the pH electrode. · Only when the reading is stable the probe indicator " " will stop flashing (after about 30 seconds) and the "CFM" indicator will start blinking. · Press CFM to confirm the calibration; if the reading is close to the selected buffer, the meter stores the reading, adjusting the 2nd slope point and the calibration process is ended with the offset and the 1st and 2nd slope of the meter calibrated. If the reading is not close to the selected buffer, "WRONG " will blink. BUF Note During calibration, the secondary LCD displays the selected buffer value. By pressing LCD the temperature can be displayed. This will allow you to check the buffer temperature during calibration. 31 CALIBRATION WITH MANUAL TEMPERATURE COMPENSATION · Enter the calibration procedure and press LCD to display the temperature on the secondary LCD. · Unplug any temperature probe that may be attached to the meter. The "°C" symbol will flash. · Note the temperature of the buffer solutions with a ChecktempC or an accurate thermometer with a resolution of 0. 1°C. · Use or to manually adjust the display reading to the value of the reference thermometer (e. g. 20°C). · Follow the calibration procedure above (see page 27). Note To toggle between the pH buffer and the temperature press LCD. When a one-point calibration is carried out only the pH offset is computed and stored, while the pH slope is fixed according to the theoretical values. With a two-point calibration, offset and slope are computed to fit the two calibration points. With a three-point calibration the offset and first slope values refers to pH 4. 01 and 7. 01 buffers, while the second slope refers to pH 7. 01 and 10. 01 buffers. Note If the process meter has never been calibrated or an EEPROM reset has occurred, the meter continues to perform measurement. However, user is informed of a pH calibration requirement by a blinking "CAL" (see "Startup" section). [. . . ] The protective cap can also be filled with HI 70300 Storage Solution if the electrode is not being used at all. With industrial applications, it is always recommended to keep at least one spare electrode handy. When anomalies are not resolved with a simple maintenance, change the electrode to see if the problem is alleviated. 53 ACCESSORIES pH CALIBRATION SOLUTIONS HI 7004M pH 4. 01 Buffer Solution, 230 mL HI 7004L pH 4. 01 Buffer Solution, 460 mL HI 7004/L pH 4. 01 Buffer Solution, 1 L HI 7007M pH 7. 01 Buffer Solution, 230 mL HI 7007L pH 7. 01 Buffer Solution, 460 mL HI 7007/L pH 7. 01 Buffer Solution, 1 L HI 7010M pH 10. 01 Buffer Solution, 230 mL HI 7010L pH 10. 01 Buffer Solution, 460 mL HI 7010/L pH 10. 01 Buffer Solution, 1 L ORP SOLUTIONS HI 7020M HI 7020L HI 7091M HI 7091L HI 7092M HI 7092L 200-275mV Buffer Solution, 230 mL 200-275mV Buffer Solution, 460 mL Pretreatment Reducing Solution, 230 mL Pretreatment Reducing Solution, 460 mL Pretreatment Oxidizing Solution, 230 mL Pretreatment Oxidizing Solution, 460 mL ELECTRODE STORAGE SOLUTIONS HI 70300M Storage Solution, 230 mL HI 70300L Storage Solution, 460 mL ELECTRODE CLEANING SOLUTIONS HI 7061M General Cleaning Sol. , 230 mL HI 7061L General Cleaning Sol. , 460 mL HI 7073M Protein Cleaning Sol. , 230 mL HI 7073L Protein Cleaning Sol. , 460 mL HI 7074M Inorganic Cleaning Sol. , 230 mL HI 7074L Inorganic Cleaning Sol. , 460 mL HI 7077M Oil & Fat Cleaning Sol. , 230 mL HI 7077L Oil & Fat Cleaning Sol. , 460 mL REFILL ELECTROLYTE SOLUTIONS HI 7071 3. 5M KCl+AgCl Electrolyte, 4x50 mL, for single junction electrodes HI 7072 1M KNO3 Electrolyte, 4x50 mL HI 7082 3. 5M KCl Electrolyte, 4x50 mL, for double junction electrodes 54 RECOMMENDED pH ELECTRODES (All electrodes gel-filled and with ceramic junction unless otherwise indicated).
