[. . . ] Instruction Manual HI 9023C - HI 9023CN HI 9024C - HI 9025C HI 9110 - HI 9210 HI 9210N Portable Waterproof pH Meters Dear Customer, Thank you for choosing a Hanna Product. Please read this instruction manual carefully before using the instrument. It will provide you with the necessary information for a correct use of the instrument, as well as a precise idea of its versatility. If you require further technical information, do not hesitate to e-mail us at tech@hannainst. com. [. . . ] With the temperature probe located CAL 1 CAL BUF pH as close to it as possible. CAL TWO-POINT CALIBRATION After calibrating at 6. 86 or 7. 01 pH (see above), for the second buffer use pH 4. 01 if you are going to measure acidic samples, and pH 9. 18 or pH 10. 01 if you are measuring alkaline solutions. · Proceed as described in "One-point calibration above but do not end the calibration by pressing CAL. · After the first calibration point is confirmed, immerse the pH electrode into the second buffer solution (pH 4. 01, 9. 18 or 10. 01) and stir gently. Note: The electrode should be submerged approximately 4 cm (1½") into the solution with the temperature probe located as close to it as possible. · Select the second buffer value on the or secondary display by pressing the °C or C key. HI 7004 °C 1 BUF °C 4 cm (1½") °C pH 19 20 °C Note: The electrode should be submerged approximately 4 cm (1½") into the solution with the temperature probe located as close to it as possible. · Select the second buffer value on the secondary display by READY CON · Press pH/ C SET key for HI 9110 or the RANGE key for HI 9210 to select the manual temperature setting. The " C" symbol will be displayed to indicate the temperature setting mode. WRONG WRONG CFM BUF 2 °C pressing the °C or C key. · When the "READY" and "CON" symbols blink on the display, the reading is stable and the calibration can be confirmed. If the reading is not close to the selected buffer solution, "WRONG 2 " and "WRONG " will blink alternatively. If the reading is close to the selected buffer, the slope and the offset are calibrated. The values will be stored in memory and the meter will return to the operating mode. Note: The meter will automatically skip the buffer that was used for the first calibration to avoid erroneous calibration. At least 1 full pH unit is required between the two buffers used for the offset and slope calibration. As a result, once calibrated at either pH 6. 86 or 7. 01, the microprocessor will automatically ignore the other one for the second point calibration. It will do likewise for pH 9. 18 and 10. 01 Note: During calibration, the secondary LCD displays the selected buffer value. With HI 9025C, press the RANGE key to display the buffer temperature during calibration. BUF · Remove the protective cap on the top of the meter to have access to the calibration trimmers. pH °C SET RANGE PROCEDURE FOR HI 9110, HI 9210 & HI 9210N: Manual Temperature Compensation Note: The pH/ C electrode of HI 9210N incorporates a temperature sensor which performs automatic temperature pH °C SET °C · Record the temperature of the buffer with a Checktemp C or an accurate thermometer (e. g. 20 C). · Using the screwdriver, turn the temperature trimmer (# 5 pages 9-10) to display the recorded temperature value. · Press the pH/ C SET key for HI 9110 or the RANGE key for HI 9210 to read pH. As a result, you can perform one or two point calibration at a buffer of your choice. The instructions below explain a typical calibration procedure at pH 7 and then 4 or 10. · Remove the protective cap from the electrode, rinse it with some pH 7. 01 solution, then dip in pH 7. 01 buffer. Note: The electrode should be submerged approximately 4 cm °C HI 7007 RANGE compensation.
