This trigger point forthis alert is dependent upon the conductivity measurement technology:<strong>1066</strong>C: (conductance - zero offset) < -2µS<strong>1066</strong>T: (conductance - zero offset) < -50µSA sensor zero calibration should be performed.Concentration Out Of Range / WarningThe measured concentration is outside the conductivity range where a valid concentrationcan be derived for the following 5 concentrations:0 to 20% NaCl0 to 12% NaOH0 to 15% HCl0 to 25% H2SO496 to 99.7% H2SO4.If there are no other fault conditions check process temperature and check thatthe actual concentration is outside the range for which curve is defined.Input Out Of Range / WarningThe input is outside the device measurement range. the range limits are:<strong>1066</strong>C (2- electrode conductivity): Conductance > 500mS<strong>1066</strong>CT (4- electrode conductivity): (Conductance > 3000mS) or (Vcond < 0mV)<strong>1066</strong>T: Conductance > 1500mS1.
