Analyzer OperationChannel Specific SetupMode Menu OptionsCH1 or CH2If a two channel analyzer is in use, the following setup mode menu optionsare specific to the first channel of the 2110XP analyzer for ammoniameasurements. When a pH/ORP module or conductivity module isinstalled on the second channel of the 2110XP analyzer, refer to the ThermoScientific Orion 2100 Series pH/ORP Analyzer and Conductivity AnalyzerUser Guide for detailed instructions on the second channel setup modemenu options.The operator must select the channel number in the main setup mode(CH1 or CH2) and the menu options that are relative to the measurementcapability of that channel will be displayed. If a one channel analyzer isbeing used, the CH1 and CH2 menus will not be shown.MEASSet the number of significant digits, mV display option and concentrationunits displayed when in the measure mode:• Set the number of significant digits displayed measure mode• Scroll through 2, 3 or 4 significant digits• Default significant digits – 3• Enable mV values to be displayed on the second line• Scroll between On or OFF• Default mV setting – OFF• Set the displayed concentration units• Scroll through AUtO (automatically ranges from ppb to ppm), PPb(parts per billion, ppb), or PP (parts per million, ppm)• Default displayed concentration units – AUtOHOLDSet the time that the system will remain on hold before the actualmeasurements are displayed after a calibration:• Once the hold time expires, the system implements any programmedchanges to settings in the setup mode• After a calibration, the hold function allows the operator to rinse theelectrodes prior to recording actual measurement values• Default hold time – 30 minutesTADJAdjust the temperature reading from the ATC probe by ± 5.0 °C:• Default adjustment – 0.0 degrees CThermo Scientific Orion 2110XP Ammonia Analyzer User GuideIII-7
