No moving average is calculated.<br />
2 A moving average is calculated twice per sampling interval.<br />
5 A moving average is calculated 5 times per sampling interval.<br />
10 A moving average is calculated 10 times per sampling interval.<br />
20 A moving average is calculated 20 times per sampling interval.<br />
40 A moving average is calculated 40 times per sampling interval.<br />
<br />
Filter processing performed on the GL820 is the moving average shown in the following figure.<br />
n-5<br />
n-4<br />
n-3<br />
n-2<br />
n-1 n<br />
D<br />
If the filter setting is 5,<br />
D=(n-4 + n-3 + n-1 + n)÷5<br />
If the sample interval exceeds 30 seconds, the average value of data obtained in a sub-sample (30<br />
seconds) is used.<br />
