Power supply: 5, dual batteries and powerMeasurement, the replacement of the corresponding probe, followed by individual measurement2.Easy to use multi-function water quality analyzer instructions and precautionsStart instruments: power or install the battery, press the red button to start the instrument. Measuring instruments: 1)Temperature measurements: the temperature corresponding to the electrode connector into the socket on the instrument (the socket marked T), the temperature of the electrode into the solution under test, press the measure key to measurements, stable value, or appear to be OK, press the Enter key to end , press the Enter key to return to the main menu. 2)Salinity measurements: the temperature corresponding to the electrode inserted into the socket on the instrument, the salinity of the electrode plug the jack marked with S, press the left or right button, move the cursor to the bottom of S, the temperature and salinity Electrodes are placed in the solution under test, press the measure key to measurements, the instrument will first temperature measurement, numerical stability and press OK key measure salinity, temperature data appears to be OK, or after the instrument directly to the salinity measurements. Salinity values ​​to be stable, or appear OK, press the Enter key to end, press the OK button to return to the main menu。3) the temperature measurement of dissolved oxygen electrodes inserted into the corresponding socket on the instrument, the dissolved oxygen electrode plug into the jack marked with the DO, press the left or right button, move the cursor to the bottom DO, the temperature and dissolvedoxygen electrodes were placed in the solution under test, measured by measuring key, gently shake the dissolved oxygen electrode, the instrument will first temperature measurement, numerical stability of dissolved oxygen measurement and press OK button, or when the temperature value occurs after the equipment will be OKDirect measurements of dissolved oxygen, dissolved oxygen values ​​to be stable, or appear OK, press the Enter key to end, return to the main menu.4) PH measuring the temperature of the electrode into the instrument corresponding to outlet, PH electrode plug into the jack marked with the PX, press the left or right button, move the cursor to the bottom of PH, both the temperature and the PH electrodeinto the solution under test, press the measure key to measurements, the instrument will first temperature measurement, numerical stable PH value measurement press the Enter key, or value appears to be OK after the temperature instrument to measure directly on the PH, PH value and stability to beor after there OK, press the Enter key to end, return to the main menu.5) 50ml solution of ammonia measurements taken under test around the temperature corresponding to the electrode inserted into the socket on the instrument, the ammonia electrode plug into the jack marked with the PX, the ammonia electrode shell unscrewed, put two droppersammonia in liquid-filled, and then screw down and put it into distilled water or water, press left or right button, move the cursor to E below, press the button to wash the blank measurement potential, more potential value to 50mv, press the Enter key, appears OK, then press OK button to return to the main menu to remove the ammonia electrode, dried with filter paper, the temperature and ammonia electrodes are placed under test solution, in the tested solution with a dropper to add 4 to 5 drops of ammonia buffer solution (10M/ LNaOH solution), stir, move the cursor to the bottom of NH3, press the measure key to measurements, the instrument will first temperature measurement, numerical stability of ammonia measurement and press OK key value, or value appears to be OK after the temperature of the instrument will directlyammonia measured values ​​to be stable ammonia or there OK, press the Enter key to end, return to the main menu.After the ammonia electrode measurement can be placed in distilled water or water potential in the space allowed to self-cleaning (no need to use equipment cleaning), so you can use, will not have to re-wash before use blank potential.6) Hydrogen sulfide measurements taken around 50ml solution under test, the temperature of the electrode into the corresponding socket on the instrument, the hydrogen sulfide electrode PX plug into the jack marked on the shell of the hydrogen sulfide unscrew the electrode, into thedropper filled within two hydrogen sulfide, and then screw down and put it into distilled water or water, press the left or right button, move the cursor to E below, press the button to wash the blank measurement potential, the potential value reached after the above-200mv, press the Enter key, appears OK, then OK button to return to the main menu, to remove hydrogen sulfide electrode, dried with filter paper, the temperature and hydrogen sulfide electrodes are placed under test solution, with a dropper to add in the tested solution4 to 5 drops of liquid hydrogen sulfide slow adjustment (10M/LNaOH solution), stir, press the left or right button, move the cursor to the bottom of H2S, press the measure key to measurements, the instrument will first temperature measurement, numerical stabilitymeasurement of hydrogen sulfide and press OK key value, or value appears to be OK after the temperature instrument to measure directly on the hydrogen sulfide, hydrogen sulfide to be numerically stable and press OK key to end, return to the main menu.Hydrogen sulfide can be measured after the electrode into the distilled water or water potential in the space allowed to self-cleaning (no need to use equipment cleaning), so you can use, will not have to re-wash before use blank potential. NotesDropper can not be mixed, a solution can only be used for each pipette, or dropper clean after use. Salinity of the electrode into the water after use save as much as possible. PH electrode should be placed after use with the protection of its original solution to save, when used in its attention to the protective solution for safe place to prevent accidentally knocked over. of ammonia and hydrogen sulfide electrode must be added prior to use and clean filling gaps within the potential, otherwise it would be inaccurate values​​. dissolved oxygen membrane electrode should pay attention to the protection, do not let the tip hit a hard object not to touch the membrane oxygen the oxygen membrane. After use the electrode into the water as far as possible preserved, and its surface membrane can be no more than just peroxide solder joints at the oxygen electrode. electrode should be cleaned after use, then dry with filter paper electrode in accordance with the requirements of each save. ammonia and hydrogen sulfide electrode are both filled dropper dosage (volume inhaled per dropper dropper total capacity of about 1 / 3 can). ammonia and hydrogen sulfide potential of the electrode gap when cleaning the electrode in distilled water or water in the rock so that the rapid increase in potential value to save time
