  • Page 7: Functions Of The Instrument

    2.3. FUNCTIONS OF THE INSTRUMENT The CA 10101E is a pH-meter designed for use in the laboratory. It can be used to measure pH, temperature, and oxidation reduction potential (ORP), depending on which electrode is connected. It also enables the pH or ORP measurement value to be provided in the form of a voltage on the analogue output.

  • Page 20: Analogue Outputs

    3.4. ANALOGUE OUTPUTS The CA 10101E is equipped with one analogue output (two 4 mm banana socket, one red and one black) which supply continuously a voltage proportional to the pH or ORP value. Connect a voltmeter with an input impedance greater than 1 MΩ between the Vout and GND terminals of the instrument.
