Note: (1) the electrode should be installed in the bypass of the main line, the front end valve should be installed to control the flow rate, the flow should be as small as possible, generally as long as the outlet have a stable solution to drip out. Electrode should be mounted vertically and deep into the activities of water, the outlet than the inlet should be high in order to ensure the electrodes were immersed in the solution.
(2) the electrode should be calibrated before installation.
(3) measuring signal belongs to weak electrical signals, which cable should be independent of trace collection, Suppress and power lines, control lines are connected to the same set of cable connectors or terminal blocks in order to avoid interference or breakdown measurement unit.
(4) measurement cables are too short, please contact the manufacturer or supplier before the convention (generally less than 10m).
2, the electrode signal lines extend and shorten precautions:
Since the purchase of non-trial extension cable electrode wire

8. The alarm relay (control dosing) Setting
8.1 If you add acid to adjust lye, such as requiring the addition of acid PH value of more than nine, to adjust to after 6 stops, should first dosing pump power the zero line cut, and then the two thread connected to a high point after the meter dial namely " HI "two terminals, then set the high point of the relay:
Press the "OK" button, enter your password into the "Setup Menu" screen, select "Control Parameters" Press "OK" button, then select "Set high alarm" will pull high value is set to 9, the high point off value set to 6, press "OK" button. You can now achieve more than 9 PH value added acid, adjusted to stop after six.
8.2 If alkali regulate acid, such as requiring PH value of less than 6 alkali, adjusted to stop after 9, two thread should first dosing pump power cut after the zero line connected to the meter dial lows namely " LO "two terminals, then set low relay:
Press the "OK" button, enter your password into the "Setup Menu" screen, select "Control Parameters" Press "OK" and then choose "underreporting Settings" will pull low value is set to 6, the low value is set to OFF 9. Press "OK" button. It can now achieve PH value of less than 6 adding alkali to adjust to after 9 stops.
Note:
Relay drive inductive load, please install the intermediate relay, to avoid being back EMF when the contact breaking inductance breakdown ionization, burning the contacts.
9. Maintenance:
Section 9.1 PH
9.1.1 Instrument maintenance:
(1) The instrument input (measuring electrode sockets) must be kept dry and clean to prevent dust and moisture intrusion.
(2) should avoid long electrode immersed in a protein solution and acid fluoride solution, avoid contact with the silicone oil.
(3) after long-term use of the electrode, such as found in slope slightly lower, the lower end of the electrode can be immersed in 4% HF solution (hydrofluoric acid) for 3 to 5 seconds, and then washed with distilled water, then 0.1mol / L hydrochloric acid immersion the electrode Fuxin.
(4) In order to more accurately measure shall be regularly calibrated electrodes and washed with distilled water.
(5) The instrument should be placed in a dry environment or control box, to avoid water droplets caused by sputtering or moisture meter drain or measurement error.
9.1.2 Instrument Calibration:
9.1.2 correction before work, check the instrument wiring is correct, the Power warm up for 30 minutes.
9.1.3 with a good 4.00pH, 6.86pH, 9.18pH three standard solution.
Method: use distilled water, distilled water twice distilled better, cut the plastic bag in the reagent into the beaker, with the amount of deionized water to dissolve and wash bags, then pour 250ml volumetric flask, dilute to the mark fully shake well, pour sample bottle label use.
9.1.4 The electrode rinse with distilled water and a clean and dry with filter paper, and then the electrode into a standard buffer 4.00pH gently stirring several times, the screen displays "4.00pH Calibration", the central display mV output voltage value of the electrode. Wait at least one minute, until mV after stabilization press "Enter OK" is calibrated, 4.00 will be prompted after the completion of a successful calibration.
9.1.5 Repeat the above two steps, namely calibration 6.86pH, 9.18pH and two points. After each label a standard solution, the electrode must use distilled water to clean and dry with filter paper before they can be put under a standard standard liquid inside.
9.1.6 above calibration is completed automatically goes into solution temperature calibration interface, and if automatic temperature compensation, display solution temperature measuring electrode, if manual temperature compensation, you can enter the solution temperature using the keys, press the "Enter OK" to save the parameter that is complete calibration,
NOTE: If you do not strictly follow the above steps, at any step press "Exit ESC" to exit to the main screen, in front of the calibration parameters are not saved.

9.2 ORP part
9.2.1 ORP standard solution preparation methods:
(1) 86mV: Standard 7.00pH buffer solution was added a slight excess quinhydrone.
(2) 256 mV: Standard 4.00pH buffer solution was added a slight excess quinhydrone.
(3) standard solution to save time is 3 days
9.2.2 ORP electrode detection:
(1) ORP electrodes do not like PH electrodes require calibration standard solution, but it must mV standard solution to check ORP electrodes, the most important aim is to see whether the effective electrode.
(2) the electrode clean with water and wipe with a soft towel.
(3) the electrode into standard solution prepared mV until the display is stable.
(4) to see whether the display mV value is close to the standard solution, if the error is within plus or minus 35mV, the electrode can be used normally, or we need to change the electrode
