9 1 Description The Microprocessor pH Meter CG 839 can be used to make pH-value, redox voltage and temperature measurements. The measured temperature is shown in the display parallel to the pH or mV value. The calibration data for pH measurements are preserved when the Microprocessor pH Meter CG 839 is switched off. For adjustment to match the electrode function, the data for three buffer solutions, including their temperature characteristics, are stored in the Microprocessor pH Meter CG 839.
10 6 pH-measurement with combination pH-electrode and separate temperature sensor Pt 1000 pH-measurement with automatic temperature-compensation is possible too using a combination pHelectrode and a separate Pt 1000 temperature sensor. In this case, connect one plug of the temperature sensor to the socket marked Pt 1000 and connect the other plug to the reference electrode socket. 7 pH-measurement with manual temperature compensation When using an electrode without integrated temperature sensor (e. g.
11 13 Error messages <>: Overshoot of the measuring range. This error message disappears again automatically when the reading returns to within the measuring range. <>: The response time of the electrode is too long (greater than 1 minute). This error message appears during the calibration procedure. Usually the cause is that the electrode has not been watered properly or is too old. <> also appears when no electrode is connected.
