7) Maximal value and Minimal value hold
・Use it, when maximal value or minimal value hold is selected as a Hold
Function (Hold).
Set minimal value, detection level, and detection count.
a) Detection minimal value (Minimal Value)
Set it on the 10-key input screen.
Setting ranges : 1 to 9999
b) Detection level (Detection Level)
Set it on the set-value select screen.
Setting items : 1/4, 1/2, 3/4, 1, 1.25, 1.5, 2, 3, 4 times
c) Detection count (Detection Count)
Set it on the 10-key input screen.
Setting ranges : 1 to 9
・Detection of maximal value and minimal value
When "value A- value B = value C" is over the Minimal Value, value A
becomes maximal value and value B becomes minimal value.
・Hold of maximal value and minimal value
In case of maximal value hold, when value C × "Detection Level" is exceeded
after detecting the maximal value and minimal value, value A is indicated and
held. In case of minimal value hold, value B is displayed and held.
・In case of a waveform of which maximal value and minimal value repeat, the
maximal value and minimal value of which number of times is set as a
Detection Count is hold.
Caution！
When the indicated value contains much noise, the maximal value and
minimal value of noise may be sometimes detected. Check the indicated
value on the screen and set the proper minimal value (Minimal Value).
For example, at the setting of Detection Count = 3, E is held as maximal
value and F as minimal value.
8) Inflection point hold
・Use it when inflection point hold ((17)) is selected by the Hold Function
(Hold).
Set the detected Inflection range, inflection before and inflection after.
a) Detected point of inflection value (Inflection Range)
Set it on the 10-key input screen.
Setting ranges : 1 to 99999
b) Detection time A (Inflection Before)
Detection time is (1/sampling speed × set value).
Set it on the 10-key input screen.
Setting range : 1 to 999
c) Detection time B (Inflection After)
Detection time is (1/sampling speed x set value).
Set it on the 10-key input screen.
E
Setting ranges : 1 to 999
・Hold of point of inflection
C
Where the value obtained by subtracting the indicated value of variable C
C
during "Inflection Before" from the indicated value of variable D during
"Inflection After" is E, point "i" is held as a point of inflection when the value
of variable E exceeds the detected point-of-infection value.
