Rolling Average
ON/OFF
To take the rolling average of the measured results, select [ON].
Interval
Select the sampling interval when taking the rolling average from the following: The
sampling interval takes on a value that is an integer multiple of the scan interval. For
example, if the sampling interval is set to 5 s when the scan interval is 2 s, the actual
sampling interval is 6 s.
Count (Number of samples)
Set the number of samples for the rolling average using an integer between 1 and 1500.
The rolling average time is equal to the sampling interval × the number of samples.
Note
RD-MV1000/RD-MV2000 Specifications
• If the number of data points to be averaged has not reached the specified number of samples
immediately after computation is started, the average of the available data is calculated.
• Computation error data is excluded from the rolling average computation.
• If the computed data exceeds the upper or lower limit, the data is clipped at the upper or
lower limit, and the rolling average is computed. The upper and lower limit is “±100000000”
excluding the decimal point. The decimal place is the same as that of the span lower limit.
Memory Smpling, Zone, Graph, Partial, Color, Green Band, and Alarm Mark
The settings are the same as the measurement channels. For details, see section 6.3,
“Setting the Measurement Channel, Ext. Channel.”
Constant
You can set constants to be used in the expression. Up to 60 constants can be specified.
Copying and Pasting Setup Data
See section 6.3, “Setting the Measurement Channel, Ext. Channel.”
