Averaging Function
The user can set the averaging function via this menu. When the input signal frequency is low, the value is
displayed unstably and cannot be read easily. In this case, the averaging function can be enabled to calculate and
display the average value of several measurements.

Function description
State
Set the status of the averaging function. When “ON” is selected, the averaging
function is enabled. When “OFF” is selected, the averaging function is disabled.
Mode
Set the mode of the averaging function. EXP: index averaging, often used for analysis
of the non-stationary process. LINE: linear averaging, often used for measurement
and analysis of the stationary random process. The deviation relative to the standard
can be reduced by increasing the averaging times.
Type
Set the linear averaging type. MOVING: moving averaging REPEAT: repeated
averaging
Count
Set the times of the averaging function. If the mode of the averaging function is set
as EXP (index averaging), the attenuation constant can be set. If the mode of the
averaging function is set as LINE (linear averaging), the averaging times can be set.
