Electrode Protective Cover 1.2.1 Install Electrode Holder Insert electrode holder (4) in electrode base, and screw the set screw under electrode holder (4). 1.2.2 Install PH pH Combination Electrode a) Installation pH Combination pH Electrode (12) on electrode holder (4). b) Remove BNC short-circuit (11) plug on electrode socket (6). - Page 6 This instrument is available for long-term stable usage. After test samples, the electrode should be immersed in DI water. Keep the instrument interface clean, dry, and avoid contact with acid, alkali, salt solution. Insert short circuit when the instrument is not in use to avoid open circuit damage. 2.1.1 Terms pH slope: The potential variation for each pH change, usually expressed as mV/pH ...

pH：0.01pH mV：1mV 10. Repeatability error of meter: ≤0.01pH 11. Repeatability of electronic unit: 0.01 pH±l bit／3h 12. Size: ( length × width × height, mm): 290×210×95 13. Weight, kg：1.5kg 14. Normal working conditions: Ambient temperature: (5～40)℃； Relative humidity: ≤85％； Power supply：220V 50Hz There is no vibration which affects performance nearby. - Page 8 The diagram of starting interface In which: Above the screen is the current pH value, the below is setting temperature. In measuring state, press “mV/pH” key to switch between potential and pH value. Press “Temp” to set current temperature. Press “Position” and “Slope” to calibrate electrode slope.
- Page 9 3.3 To Calibrate pH electrode Calibrate electrode first before using the instrument. Generally for continuous measuring, the instrument should be calibrated everyday “E0” key for one point calibration and “Slope” key for two-point calibration. The instrument must finish “E0” calibration before “Slope” calibration. Otherwise, the “Slope”...
- Page 10 wash the electrode with distilled water and put it into buffer solution 1 (such as buffer solution pH=7.00). Measure the temperature of the solution with thermometer (such as 25℃), and set temperature value as previous method. After the reading becomes stable, press “E0 △”...

3.5 To measure potential (mV value) 1. Put measuring electrode (ion selected electrode or mental electrode) and reference electrode on electrode holder. 2. Rinse the head of electrode with DI water, and rinse it again with test solution. 3. Insert ion electrode into measurement socket (6). 4. - Page 12 The electrode converter (options) is designed for the use of other electrodes, usually moistureproof and dustproof. When measuring, remain the wire of the electrode still, otherwise it will cause unstable measurement. The instrument used by power supply should be good grounding. ...
- Page 13 1: Do not choose cleaning solutions like carbon tetrachloride, trichloroethylene, and tetrahydrofuran that can dissolve polycarbonate resin, because the electrode shell is made of polycarbonate resin. The dissolution of polycarbonate resin will easily pollute sensitive glass bulb, so that the electrode is invalid. Also, do not use combination electrodes to measure the solutions above.
