多参数水质检测仪操作手册

Dear User! We present you a device distinguished by accuracy according to the technical data and by a high stability of the displayed results. We believe that the measurements will not cause you any trouble and that the meter will operate without any inconvenience. Wide range of additional functions requires careful reading of the manual in other case some of the features may stay unused or using the meter may cause you a troubles. The employing of good-quality electrodes cells and probes and their replacing after a suitable time ensures obtaining of high measuring parameters. We want to call your attention to the fact, that this equipment has a much shorter working life than the meter. Typical symptoms of an improper operation of the electrode are deterioration of final result stability, it’s flowing as well as a higher measuring error. Part of the users has problems, arising from employing electrodes not being preconditioned before the measurement or making the measurements without removing the shielding ring from the liquid junction or taking measurements with a plugged junction. To avoid this situation it is necessary to choose the proper kind of electrode for solutions which are going to be measured ex. special electrodes for the sewage, liquids with deposits, meat cheese etc. Therefore, if you observe improper operation of the device, please take control measurements with another electrode or check the used electrode with another pH-meter. Generally the deterioration of the meter work is caused by the electrode and not by the meter. In case of conductivity measurements it is important to choose the cell with right constant K value for the measuring range. Wrong selection may cause larger error occur, similar situation occurs during measurements with automatic temperature compensation with incorrectly introduced  coefficient. Accuracy of the dissolved oxygen measurements depends on the sensor calibration and regular maintenance which consist in replacing the membranes, electrolyte and cleaning the electrodes. Lack of correct maintaining of the sensor after some time will make measurements impossible. Please turn your attention to the fact that stabile measurement is possible only with simulated or natural measured water flow. The essential feature of our products is their low failure frequency. However if your meter will fail, our firm immediately performs its warranty repair. We wish you a pleasant and trouble-free work with our meter.
