Remove the battery compartment cover on the back of the meter, install the battery while paying attention to its polarity. · Always remove the electrode protective cap before taking any measurements. If the electrode has been left dry, soak the tip in HI 70300 Storage Solution for half an hour to reactivate it. · Connect the pH electrode to the screw type connector on the meter. Be sure that the electrode and the meter connections are clean and dry to ensure a positive contact. Turn the meter on by pressing ON/OFF. Note: After use, rinse the electrode with water to minimize contamination and store it with a few drops of storage (HI 70300) or pH7 (HI 7007) solution in the protective cap. Note: Always turn the meter OFF and replace the electrode protective cap after use. NEVER USE DISTILLED OR DEIONIZED WATER FOR STORAGE PURPOSES. pH CALIBRATION · Connect the electrode and switch the meter ON. · For a single-point calibration, place the electrode in any buffer, eg. · When the pH tag stops blinking, press the SET/HOLD button to confirm the calibration point. Note: If the pH 7. 01 buffer was used, press the SET/HOLD button again to exit the Calibration mode; the first calibration point is stored and the meter returns to the measurement mode. Otherwise, if a different buffer was used, the meter will automatically return to normal mode. · For a two-point calibration, place the electrode in pH 7. 01 buffer. · When the pH tag stops blinking, press the SET/HOLD button to confirm and store the first calibration point. · When also this buffer is recognized (the pH tag stops blinking), press the SET/HOLD button to confirm and store the second calibration point; the meter will return to normal mode. Note: If a solution with wrong pH value is used as buffer for calibration, the LCD will display the "Ec" message. Note: To reset to the default values, after entering the Calibration mode and before the first calibration point is confirmed (pH tag is blinking), press and hold the SET/ HOLD key, and then press the CAL button. The meter displays "CLr" for a few seconds and then return to normal mode. [. . . ] The meter is also provided with BEPS (Battery Error Preventing System), which avoids any erroneous reading due to low battery level by warning the user with the "Eb" message on the LCD and switching the meter off when the battery is completely rundown. Remove the cover on the back of the meter and replace the battery with a new one, while paying attention to its polarity. Replacement must only take place in a nonhazardous area using an alkaline 9V battery. Recommendations for Users Before using this product, make sure that it is entirely suitable for the environment in which they are used. Operation of this instrument in residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary steps to correct interferences.
