OPERATIONAL GUIDE To connect the probe Connect the FC 202D probe to the DIN socket on the top of the meter by aligning the pins and pushing in the plug. Tighten the nut to ensure a good connection. [. . . ] · If measurements are taken in different samples successively, clean the probe tip thoroughly to eliminate crosscontamination. For cleaning procedure choose the suitable Hanna cleaning solution (see "Accessories" section). pH calibration · Press and hold the ON/OFF/MODE button, until OFF on the bottom display is replaced by CAL. The LCD displays "pH 7. 01 USE" or "pH 6. 86 USE" (if you selected the NIST buffer set). · For a single point pH calibration, place the probe in any buffer from the selected buffer set (eg. The meter automatically recognizes the buffer value and displays OK for 1 second. If the pH 7. 01 buffer (or 6. 86 if you selected the NIST buffer set) was used, press the ON/OFF/MODE button to return to the pH measuring mode. · For a two point pH calibration, place the probe in pH 7. 01 (or 6. 86, if you selected the NIST buffer set). The LCD displays the recognized buffer value and OK for 1 second and then "pH 4. 01 USE". Place the probe in the second buffer solution (pH 4. 01 or 10. 01, or, if using NIST, pH 4. 01 or 9. 18). When the second buffer is recognized, the LCD displays OK for 1 second and the meter returns to normal measuring mode. To reset to the default calibration To clear a previous calibration, press the ON/OFF/MODE button after entering the calibration mode. The bottom LCD displays ESC for 1 second and the meter returns to normal measuring mode. The "CAL" symbol on the LCD disappears and the meter resets to the default calibration. METER SETUP · Press and hold the ON/OFF/MODE button for about 6 seconds, until CAL on the bottom display is replaced by TEMP and the current temperature unit (e. g. Then: · for °C/°F selection, use the SET/HOLD button. After the temperature unit has been selected, press ON/OFF/MODE to enter the buffer set selection mode; press ON/OFF/MODE twice to return to the normal measuring mode. · to change the calibration buffer set, after setting the temperature unit, the meter will show the current buffer set: pH 7. 01 BUFF (for 4. 01/7. 01/10. 01) or pH 6. 86 BUFF (for 4. 01/ 6. 86/9. 18). Change the set with the SET/HOLD button, then press ON/OFF/MODE to return to normal mode. [. . . ] If service is required, contact the dealer from whom you purchased the instrument. If under warranty, report the model number, date of purchase, serial number and the nature of the problem. If the repair is not covered by the warranty, you will be notified of the charges incurred.
