Character 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.
Type
Set the linear averaging type. 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.
Tcontrol
Set the mode of the averaging function. 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.
