Setting
Remarks
C-36
Operating dif-
ferential pressure
setting for control
optimization
0: Low differential pressure
(50 ± 50 kPa)
1: Standard differential pressure
(200 ± 100 kPa)
2: High differential pressure
(300+0, -100 kPa)
1 When the setting corresponds to the
actual operating differential pressure,
control can be optimized.
(When "0" is set, the control response
speed becomes fast.
When "2" is set, the control response
speed becomes slow.)
C-37

Flow rate display
unit selection
0: Flow rate is displayed in the
standard flow rate unit.
1: Flow rate is displayed in [L/
min] at all times.
-1: Flow rate is displayed in [mL/
min] at all times.
0 0: When the flow rate range or gas
type is changed, the unit is auto-
matically changed to the display
unit so that the range after change
becomes the maximum resolution.
1: A value less than 0.001[L/min] is
not displayed
C-38
PV (instantaneous
flow rate) display
decimal point
change function
0: Decimal point position is not
changed
1: Decimal point position is
shifted one digit left
-1: Decimal point position is
shifted one digit right
0 The decimal point position of the SP
display is not changed.
1: When the standard decimal point
position is the 4th digit (0.xxx), the
function is invalid even though
this setting is selected. If the flow
rate exceeds the display range, a
dash is displayed for all digits (----).
-1: When the standard flow rate
display does not have a decimal
point, it is invalid even though this
function is selected.
*1. If “4” (flow rate setting method switching) is selected for one of the external contact input func-
tion assignments (C-10 to C-12), switching by external contacts has priority.
*2. According to the settings in
c-05
and
c-06
, the analog input and output ranges are changed
as shown in the table below.
