Mean value = (Data 4 + Data 3 + Data 2 + Data 1) ÷ 4
5. With the fifth cycle, Data 5 is stored in the first history buffer.

Mean value = (Data 5 + Data 4 + Data 3 + Data 2) ÷ 4
When a disconnection is restored, the mean value processing function begins
again from step 1.
1. When the mean value processing function is used, the delay in refreshing
converted data for input signal changes will be as shown in the following
diagram.
2. Specify "no mean value processing" to follow conversion of a rapid change
in input signals.

For V = 20 V ( − 10 to 10 V)
When Resolution is 1 ms/4,000
• For One Word
t = n + (2 to 3)
• For m Words (1 < m ≤ 4)
No averaging (n = 1) or two averaging buffers (n = 2)
t = n × (m + 2)
For n averaging buffers (4 ≤ n ≤ 64)
t = (n − 2) × m + 10.5
When Resolution is 500 µ s/8,000
• For One Word
t = [n + (2 to 3)] × 1/4
• For m Words (1 < m ≤ 4)
No averaging (n = 1) or two averaging buffers (n = 2)
t = n × (m + 2) × 1/2
For n averaging buffers (4 ≤ n ≤ 64)
t = [(n − 2) × m + 10.5] × 1/2
