NOTE
*: The pulse width with the exception of “50%
Duty” is the “Closed (On)” time for each pulse
in case that “Closed (On) Act”. Refer to the
example 1 of F11: DO Active Mode.
A limit applies to the maximum pulse scale
that can be set with respect to the pulse width.
If a value in excess of this limit is set, a setting
alarm will be displayed.
[E13: Pulse Low Cut] Setting of the pulse output
stop range
This parameter allows the setting to be made which
prevent pulse output when the flow rate is at or
below the low-cut setting value.
The low cut setting value depends on flow rate
span.
● Flow rate span < 1 m/s:
Input value or 3 cm/s, whichever is bigger
● Flow rate span ≥ 1 m/s:
Input value
To confirm the flow rate span velocity in ”m/s” unit,
see [C44: Velocity Check].
If the multiple ranges or forward/reverse ranges is
used, low cut is carried out at the setting value for
the smallest span.
However, the low cut function will be terminated if
this parameter is set to “0 %”.
NOTE
When the low cut is small, an incorrect output
may occur at the flow rate of zero and a
pulse may be output. Use the instrument with
the default setting 3%. If the span is small,
the damping time is short, or the fluid is low
conductivity, a pulse may be output easily at the
flow rate of zero. In this case, set the span to be
large, set the damping time to be long, or set the
low cut to be large.
[E14: Pulse Rate Check] Display of the pulse
output rate in “Pulse/s”
This parameter displays the pulse output rate,
which is converted to “Pulse/s” while 100% of the
range flows.
When the multiple ranges or forward/reverse
ranges are used, the AXR displays the pulse output
rate which 100% of their maximum range flows.
