Setting the smooth function
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 following procedures will show you how to enable or disable the
smooth function, and set the parameters for the fluctuation counts and
number of points of the smooth function.
1 To access the utility menu, press Shift > Utility.
2 The first utility menu item (Error) will be shown in the upper
secondary display.
3 Press or until the menu item “SMoth” is shown in the upper
secondary display.
NOTE
The smooth function calculation can be restarted by pressing MinMax for
more than one second.
