Digital filter
Digital filter in the instrument can be set from “000000” to “000007”.
Averaged−out times of digital filter can be decided from the set value(Related function
FUNC−04).
As for default, “000003” has set.
The relations between setting and average−out times are as follows:
(Average−out times) ＝ 2
n+1
n: Value at 10

digit of set value.
For example, when setting is “000003”, averaged−out times are as follows:
(Averaged−out times) ＝ 2
3+1
＝ 16 (times)
The tendency of characteristics by averaged−out times is listed below:
