M-301  pH Meter

Operating  Instructions:

1) Unpack the M-301 pH Meter,  Electrode, Adjusting Tool and pH 7 calibrating solution.
2) Connect the Electrode to the pH Meter. Mount the pH Meter in a safe dry location.
3) Plug the M-301 pH Meter into a GFCI protected outlet.
4) Place the electrode into the pH 7 solution and allow it to sit for at least 1 hour to rehydrate the  
     Electrode before use or calibration.
5) Adjust the ‘pH 7 Calibration' slotted screw on the front of the M-301 pH Meter with the     
     adjusting tool, so that the digital display reads 7.0.
6) Place the Electrode into aquarium or sump. Be sure that the White Top of the Electrode is   at 
     all times ABOVE the water level.
7) The Electrode should be cleaned periodically (approximately every 30 days or so) and        
     recalibrated to ensure proper pH readings.
