    2 Description General The instrument is used for measuring/controlling the pH, ORP or NH (ammonia) concentration. The function is switchable on the instrument itself. Depending on the measured variable, combination electrodes (e. g. pH/ORP combination electrodes, gas-sensitive sensors) or split versions (glass/metal electrodes with a separate reference electrode) can be readily connected.

    11 Appendix Separate controllers This function is normally deactivated (factory setting or "No" selection). In the deactivated state, the software prevents the two controller outputs from being able to work "against each other". So, for example, it is not possible to dose acid and lye at the same time.
