How do I prepare a CiTiceL for use?
Standard Operation CiTiceLs CiTiceLs are kept in a ‘ready-to-work’ condition whilst being shipped, by the shorting link, which connects the reference and sensing terminals. This performs the same function as the J-FET in the recommended operating circuit. (CiTiceLs which operate with an auxiliary electrode, will also have a shorting link connecting the auxiliary and reference terminals). The shorting link is removed just prior to placing the CiTiceL into its operating circuit; the sensor is now ready for calibration in the instrument. Biased Operation CiTiceLs Biased operation CiTiceLs, require the sensor’s electrodes to be at different potentials. This means that Nitric Oxide (NO), Hydrogen Chloride (HCl), Ammonia (NH3) and Ethylene Oxide (C2H4O) CiTiceLs are not shipped with a shorting link; since shorting the terminals on these sensors can cause permanent damage. Some biased operation CiTiceLs have the option of being shipped connected to a special PCB which maintains the bias poten
