the delay in the conversion data in comparison to changes in the input sig-
nals will be as shown in the following diagram.

m: Number of input words used in DM Area
n: Average number of buffers set for the input number for which to find the
response time
The following example calculations are for a resolution of 8,000 with an appli-
cation using inputs 1 and 4, 64 averaging buffers set for input 1, and no aver-
aging set for input 4.
• Response time for input 1: t = {(64 − 2) x 2 + 10.5} = 134.5 (ms)
• Response time for input 1: t = 1 x (2 + 2) = 4 (ms)
For V = 20 V ( − 10 to 10 V)
Using One Word
t = n + (2 to 3)
Using m Words (1 ≤ m ≤ 8)
No averaging (n = 1) or two averaging buffers (n = 2):
t = n x (m + 2)
n averaging buffers (4 ≤ n ≤ 64):
t = (n − 2) x m + 10.5
