[. . . ] PICCOLO ATC pH Meter OPERATION · Connect the electrode to the meter with both writings (meter and electrode) facing upwards and turn the meter on. · To perform a two point calibration, if you are measuring acidic liquids use a pH 4. 01 buffer (HI 7004 HI 7004), and for alkaline measurements use a pH 10. 01 buffer (H I 7 0 1 0 . 0) H · Rinse the electrode in water and dip it in the second buffer. [. . . ] PICCOLO will automatically compensate for the temperature variation. · When testing a new sample, it is recommended to rinse the probe with some of the sample itself prior to measurement. This prevents likelihood of cross-contamination. · When not in use, switch the PICCOLO off. BATTERY REPLACEMENT When PICCOLO cannot be switched on or the display segments fade, it is necessary to replace all 3 x 1. 4V batteries. Batteries should only be replaced in a safe area using the battery type specified in this instruction manual. Loosen the upper screw and slide off the cover on the back of the meter. Replace all three batteries while paying attention to their polarity. Reinsert the cover and tighten the screw. It is recommended to recalibrate the instrument whenever the batteries are replaced. Recommendations for Users Before using this product, ensure that it is entirely suitable for the environment in which it is used. Operation of this instrument in residential areas could cause unacceptable interference to radio and TV equipment. The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. [. . . ] H display to stabilize and using a small screwdriver slowly turn the pH 7 Calibration Trimmer to read "7. 01".
