The history buffer operational means are calculated as shown below. (In this ex-
ample there are four buffers.)
1, 2, 3... 1. With the first cycle, the data is stored with Data 1 being in all the history buff-
ers.

Mean value = (Data 1 + Data 1 + Data 1 + Data 1) B 4
2. With the second cycle, the data is stored with Data 2 being in the first history
buffer.
(Mean value

Mean value = (Data 2 + Data 1 + Data 1 + Data 1) B 4
3. With the third cycle, the data is stored with Data 3 being in the first history
buffer.
(Mean value

Conversion value
Data 3

Data 1
Mean value = (Data 3 + Data 2 + Data 1 + Data 1) B 4
4. With the fourth cycle, the Data 4 data is stored in the first history buffer.
(Mean value
processing)
Conversion value
Data 4
Data 3
Data 2
Data 1
Mean value = (Data 4 + Data 3 + Data 2 + Data 1) B 4
5. With the fifth cycle, the data is stored with Data 5 being in the first history
buffer.
(Mean value
processing)
Conversion value
Data 5
Data 4
Data 3
Data 2
Mean value = (Data 5 + Data 4 + Data 3 + Data 2) B 4
When a disconnection is restored, the mean value processing function begins
again from step 1.
