Instructions for use:
1 Connect the power AC 230V-50/60HZ.
2 pH elec
trodes were inserted into the input.
3 The pH SET set to "pH" position , the pH electrode into pH7 correction fluid , such as a few seconds , so that the displayed value is stable , with matching plastic "minus" screwdriver to adjust CAL pH7 knob , the display value 7.00 .
4 pH electrode is then removed from the pH7 correction fluid , the pH electrode into the water needed for testing.
5 The pH SET Set to "SET" position , adjust the PH SET knob until the desired value , and generally speaking, between the pH value of early planted tanks pH6.8-pH7.2, PH value of the seawater aquarium between pH8.0-pH8.4, finally plug the carbon dioxide system on the controller plugged in , then the controller will be able to take advantage of carbon dioxide released by the system to reduce the pH value.
Cleaning and maintenance: 1 Clean the electrodes , unplug the power plug , cut off the power . When 2.pH electrodes placed in the water , should not exceed the height of the electrode cap on a regular basis as early as within a month with a soft brush to clean, when not in use, the electrode is placed there only envelopes within the preservation solution , if there is a normal crystalline phenomenon . 3. pH electrode is a precision glass products , do not knock . 4 Do not hand , cloth and wipe the pH electrode alcohol and other items . 5 This product is for indoor use only.
