Hi/Lo Limit Comparisons Of Double Hold - Unipulse F377A Operation Manual

22.
A: Relative minimum hold B: Relative difference hold
When the Hold Start Level is detected after turning-ON of the SECTION signal, Relative Minimum and
Relative Difference (difference between the Relative Maximum and Relative Minimum) hold detection
starts. For the Hold Start Level, Detection Start Condition can be selected.
Also, the value is maintained until the T/H signal turns ON with the hold Detection Start
Condition External Only. The value is maintained until the T/H signal turns ON.

■HI/LO limit comparisons of double hold

You can set HI/LO-A and HI/LO-B for comparisons of Hold A and Hold B.
- HI limitA(B)
- LO limitA(B)
HI/LO Limit comparisons of Double Hold are made, and respective judgment results are output
externally.
- Hold A HI (HI-A)
- Hold A LO(LO-A)
- HI-B
- LO-B
- OK
* You can set the Comparison Timing condition for each of Hold A and Hold B.
* If the Comparison Timing condition is not met, the comparison result of the value targeted for the
Comparison Timing turns OFF.

1 EXP. HOLD FUNCTIONS
For the Relative Difference, the
indicated value is renewed at the
instant when the Relative Maximum
and Relative Minimum are fixed.
(The sensor input value applies until
the hold values are fixed.)
If there is no relative maximum/
minimum / difference in the changes
of the sensor input value, resulting in
no hold, both the HOLD and MIN*
status indications will flash.
Also, the H/E signal will not turn ON.
* DIF for Relative Difference
Initial value: 6000(8000)
Initial value: 4000(2000)
