Instruction Manual Australia: China: Egypt: Germany: Greece: Calibration Check Waterproof pH/mV/ºC Meter HI 9026 Indonesia: Japan: Korea: Malaysia: Singapore: South Africa: Taiwan: Thailand: MAN9026 01/05 United Kingdom: USA: w w w. c o m 28 1 Dear Customer, Thank you for choosing a Hanna Instruments product. Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for correct use of the instrument, as well as a precise idea of its versatility. [. . . ] If using pH electrode while in mV mode, the meter will measure the mV generated by the pH electrode. MEM & MR FUNCTIONS From normal measurement mode, pressing the MEM key will freeze the readings on the display and store into internal memory the current values (pH and temperature, or mV and temperature) together with condition and buffer segments. The MEM tag blinks and the display remains frozen until the MEM key is pressed again. Note: While in MEM mode, the user can switch between pH and mV by pressing the RANGE key. A stored value can be recalled by pressing MR: the display will show the value, together with the RCL & MEM tags, as long as the MR key is pressed. Note: Pressing MR, only the range that was active at the time MEM was pressed is shown. BACKLIGHT FEATURE The meter is provided with a Backlight feature, which can be easily toggled on and off through the keyboard by pressing the LIGHT key. Note: The backlight automatically shuts off after approximately 1 minute with no buttons pressed. 8 pH CALIBRATION SOLUTIONS HI 70004P pH 4. 01 Buffer Solution, 20 mL sachet, 25 pcs HI 70006P pH 6. 86 Buffer Solution, 20 mL sachet, 25 pcs HI 70007P pH 7. 01 Buffer Solution, 20 mL sachet, 25 pcs HI 70009P pH 9. 18 Buffer Solution, 20 mL sachet, 25 pcs HI 70010P pH 10. 01 Buffer Solution, 20 mL sachet, 25 pcs HI 7001L pH 1. 68 Buffer Solution, 500 mL bottle HI 7001M pH 1. 68 Buffer Solution, 230 mL bottle HI 7004L pH 4. 01 Buffer Solution, 500 mL bottle HI 7004M pH 4. 01 Buffer Solution, 230 mL bottle HI 7006L pH 6. 86 Buffer Solution, 500 mL bottle HI 7006M pH 6. 86 Buffer Solution, 230 mL bottle HI 7007M pH 7. 01 Buffer Solution, 500 mL bottle HI 7007M pH 7. 01 Buffer Solution, 230 mL bottle HI 7009L pH 9. 18 Buffer Solution, 500 mL bottle HI 7009M pH 9. 18 Buffer Solution, 230 mL bottle HI 7010L pH 10. 01 Buffer Solution, 500 mL bottle HI 7010M pH 10. 01 Buffer Solution, 230 mL bottle ELECTRODE STORAGE SOLUTION HI 70300L Storage Solution, 460 mL bottle HI 70300M Storage Solution, 230 mL bottle ELECTRODE CLEANING SOLUTIONS HI 70000P Electrode Rinse Solution, 20 mL sachet, 25 pcs HI 7061L General Cleaning Solution, 460 mL bottle HI 7061M General Cleaning Solution, 230 mL bottle HI 7073L Protein Cleaning Solution, 460 mL bottle HI 7073M Protein Cleaning Solution, 230 mL bottle HI 7074L Inorganic Cleaning Solution, 460 mL bottle HI 7074M Inorganic Cleaning Solution, 230 mL bottle HI 7077L Oil & Fat Cleaning Solution, 460 mL bottle HI 7077M Oil & Fat Cleaning Solution, 230 mL bottle REFILLING ELECTROLYTE SOLUTIONS (50 mL, 4 pcs) HI 7071 3. 5M KCl+AgCl Electrolyte for single junction electrodes HI 7072 1M KNO3 Electrolyte HI 7082 3. 5M KCl Electrolyte for double junction electrodes HI 8093 1M KCl+AgCl Electrolyte ORP PRETREATMENT SOLUTIONS HI 7091L Reducing Pretreatment Solution, 460 mL bottle HI 7091M Reducing Pretreatment Solution, 230 mL bottle HI 7092L Oxidizing Pretreatment Solution, 460 mL bottle HI 7092M Oxidizing Pretreatment Solution, 230 mL bottle 21 ACCESSORIES TROUBLESHOOTING GUIDE SYMPTOMS Slow reponse/excessive drift.

Meter shuts off. It is recommended to calibrate the instrument frequently, especially if high accuracy is required. The pH range should be recalibrated: a) Whenever the pH electrode is replaced. PROCEDURE The meter offers a choice of 7 memorized buffers (1. 68, 4. 01, 6. 86, 7. 01, 9. 18, 10. 01 and 12. 45 pH) and also allows the user to enter two more pH values for calibration, C1 and C2 (see Custom Buffer Selection section on page 12 for details). Pour small quantities of selected buffer solutions into clean beakers. For accurate calibration use two beakers for each buffer solution, the first one for rinsing the electrode and the second one for calibration. Remove the protective cap and rinse the electrode with some of the buffer solution to be used for the first calibration point. 6. 86), use the UP and DOWN arrow keys to change the displayed value. or pH CALIBRATION E r0, E r1, E r2 messa g e a t sta rt up . Clr messa g e a t sta rt up. Contact your dealer or any Hanna Service Center. Perform p H ca lib ra tion. Submerge the electrode approximately 4 cm (1½") into the solution, place the temperature probe as close as possible to the electrode and stir gently. The LCD will flash "NOT READY" for 12 seconds, then: if the reading is not close to the selected buffer, "WRONG " and "WRONG " will blink alternatively; if it is close to the selected buffer the meter will advise the user with an acoustic signal (if enabled) when the reading becomes stable and the display will change to "READY" and blinking "CFM". 9 20 Press the CFM key to confirm the calibration: the meter stores the first calibration point; the primary LCD will show the calibrated reading, while the secondary LCD will show the second buffer to be used for calibration (pH 4. 01). [. . . ] During calibration the instrument will automatically calibrate to the pH value corresponding to the measured or set temperature.
