[. . . ] 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. 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 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. This will allow you to check the buffer temperature during calibration. · Press CAL and the calibration process is ended with the offset and the 1st slope of the meter calibrated. 30 31 CALIBRATION WITH MANUAL TEMPERATURE COMPENSATION · Enter the calibration procedure and press LCD to display the temperature on the secondary LCD. mV INPUT CALIBRATION The pH/mV controller is factory calibrated for the mV and temperature inputs. · Short the Connection for Potential Matching Pin (#9 at page7) and the Connection for the Electrode Reference (#8 at page 7) with a jumper wire. · Attach a HI 931001 (pH 500) or HI 8427 (mV 600) simulator to the BNC socket. · Press and hold first CFM and then CAL to enter the mV Input Calibration mode. · With pH 500, the meter will ask for the calibration procedure code number. The following table lists the possible values of the input code and calibration points: INPUT CODE 0 1 POINTS 2 2 CAL. VALUES 0 & 350 or 0 & 1900* INPUT RANGE ±2000, · Unplug any temperature probe that may be attached to the meter. · 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). mV Temp. 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. 0 & 25 or 0 & 50 -9. 9 to 120. 0 °C * One of the points must be 0. 1900 mV calibration point is available on mV 600 models only. When calibrating the mV of mV 600 models, enter the calibration mode by pressing CAL and confirming the password (as for pH calibration of pH 500). · Use or to select code 0 for mV calibration and press CFM to enter. Note If the process meter has never been calibrated or an EEPROM reset has occurred, the meter continues to perform measurement. [. . . ] This can be achieved by installing the electrode in such a way that it is constantly in a well filled with the sample (stream or tank). 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. 52 53 ACCESSORIES pH CALIBRATION SOLUTIONS HI 7004M pH 4. 01 buffer solution, 230 mL bottle HI 7004L pH 4. 01 buffer solution, 500 mL bottle HI 7004/L pH 4. 01 buffer solution, 1 L bottle HI 7007M pH 7. 01 buffer solution, 230 mL bottle HI 7007L pH 7. 01 buffer solution, 500 mL bottle HI 7007/L pH 7. 01 buffer solution, 1 L bottle HI 7010M pH 10. 01 buffer solution, 230 mL bottle HI 7010L pH 10. 01 buffer solution, 500 mL bottle HI 7010/L pH 10. 01 buffer solution, 1 L bottle ORP SOLUTIONS HI 7020M HI 7020L HI 7091M HI 7091L HI 7092M HI 7092L ORP test solution at 200-275 mV, 230 mL bottle ORP test solution at 200-275 mV, 500 mL bottle Reducing pretreatment solution, 230 mL bottle Reducing pretreatment solution, 500 mL bottle Oxidizing pretreatment solution, 230 mL bottle Oxidizing pretreatment solution, 500 mL bottle RECOMMENDED pH ELECTRODES (all electrodes are gel-filled and with ceramic junction unless otherwise indicated).
