If you specify Auto you must establish the presets which trigger movement from one application to another Therefore specify the values of App 1 Hi App 2 Lo App 2 Hi and App 3 Lo These values must be entered in the measurement units chosen for the application It is assumed that although the ranges of the applications must overlap application 1 has the lowest conductivity value application 2 is next and application 3 has the highest The switching from one application to another only takes a few seconds and once a switch is made another switch can occur within a few seconds Lastly the analyzer can be configured to change applications from an external device connected to the analyzer signal inputs When one of the three application switching inputs DI1 DI2 or DI3 changes from inactive to active state the corresponding application 1 2 or 3 is activated When first configured operation starts with the lowest configured application To use this feature set Run Application to Signal Then set the active state Level as Direct or Inverted If Direct the application becomes active when the input switch closes If Inverted it becomes active when the input switch opens For example if you wanted to switch applications based on temperature instead of conductivity you could wire terminal DI to terminal 1C and terminal 1NO to terminal DI2 see Figure 7 Then configure Alarm to Temperature and Run Application to Signal Remote Refer to Fi

18. Temp Stability before accepting a change This section enables you to configure the time Stability Time allowed to attain stability and the amount of fluctuation Stability Var allowed during the calibration The value of Stability Var corresponds to the least significant digit of the measurement in the Scale you configured on page 45 Both Stability Time and Stability Var are configured individually in Meas Stability and Temp Stability First configure Meas Stability as On or Off If you configure this as On you need to specify the Stability Time between 5 and 60 seconds in 5 second increments and the Stability Var between 1 and 9 A longer time period and a smaller measurement value assures more stability during calibration NOTE AAA In specifying the Stability Var the numbers 1 through 9 refer to the last digit of the primary scale for example If scale is 20 00 mS an Stability Var value of 5 means 0 05 mS If scale is 100 0 uS an Stability Var value of 5 means 0 5 uS Thus if the Scale is 20 00 mS and a stability time of 5 and allowed fluctuation of 9 are used the values can change at a rate of 0 09 mS over 5 seconds Then repeat the procedure for Temp Stability If you configure this as On you need to specify the Stability Time between 5 and 60 seconds in 5 second increments and the Stability Var between 1 and 9 C or F Local ac Power If your analyzer was ordered to use 24 V dc supply voltage you must specify
