Utility Menu Items Setting the smooth function mmm ogo ve OLLU Erongo koc 7 The smooth function is a special short term average that differs from the average function of the MinMax operation The smooth function filters noise and stabilizes readings The average function of the MinMax operation is considered as a long term average as it uses all of the readings to perform averaging The smooth function has a fixed number of readings that will be used for averaging This fixed number is known as the number of points which you can set from the Utility menu The smooth function also includes a fluctuation count which limits the range of the readings that can be used for the averaging Smoothed readings obtained using the smooth function are easier to read as the readings are stabilized The smooth function and the average function of the MinMax operation are independent functions and mutually exclusive in which they cannot occur at the same time When the smooth function is enabled the AVG annunciator will be flashing to indicate its ON state The smooth function will start its calculations using the parameters set in the Utility menu The smooth function calculation can be restarted by pressing MinMax for more than one second Press A or V to enable or disable the smooth function on or oF U3606B User s Guide 133 4 System Related Operation Utility Menu Items 134 ILO crn s r _ lt
