How to set
■Hold setting --- Inflection point ---
If you select the inflection point hold in the hold function setting, set the inflection point detection
parameters "inflection minimum slope", "inflection front sope time" and "inflection rear sope time".
Set referring to the principle of operation only when the value cannot be held successfully with the
factory settings or when further adjustments are required.
Detection of the inflection point
The logic of detecting the inflection point is given below.
Assuming that the remainder obtained by subtracting the amount of change C of the indicated value over
A from the amount of change of the indicated value over B is D, when the amount of change D exceeds
the inflection minimum slope, point a is held as an inflection point.
If there are two or more inflection points in the hold section, the point having a larger change is held.
The inflection point is normally detected by A=B, but it may easily be detected with A<B where the
slope is gradual.
Inflection minimum slope
Setting range: 00001 - 99999
How to set
Inflection front slope time and Inflection rear slope time
Setting range: 0≦Inflection front (rear) slope time≦990
Inflection front slope time＋Inflection rear slope time≦1000
