If “instantaneous flow rate % display (FR)” is selected for the Display
Mode and A10: FLOW RATE(%) is selected for BRAIN communication,
the instantaneous flow rate % and following symbols will be displayed
only for multiple ranges and forward/reverse flow measurement.
Forward No. 1 range : [F1]
Forward No. 2 range : [F2]
Forward No. 3 range : [F3]
Forward No. 4 range : [F4]
Reverse No. 1 range : [R1]
Reverse No. 2 range : [R2]
Reverse No. 3 range : [R3]
Reverse No. 4 range : [R4]
[F40: Auto Range Hys] Setting of automatic range-
switching hysteresis width
Automatic switching takes place for multiple ranges
switching when 100% of the range is exceeded, and
this parameter allows a hysteresis width to be set for
this switching.
Refer to Figure 6.4.1: Multiple Ranges and Hysteresis
Widths.
[F41: Bi Direction Hys] Setting of forward/reverse
flow measurement hysteresis width
This parameter sets the hysteresis for forward/reverse
flow rate measurement as a % value of the minimum
flow span.
Refer to Figure 6.4.1: Multiple Ranges and Hysteresis
Widths.
(6) Menu G: Alarm Setting items
(Refer to Section 6.5: Alarm Functions for more
details.)
Menu G principally contains setting items relevant to
alarms.
[G10: Low Alarm] Low alarm setting
This parameter sets the low limit (L) alarm value, and
this is done using a % value of the maximum span.
᭹ A setting value of -110% indicates that the alarm is
disabled.
[G11: High Alarm] High alarm setting
This parameter sets the high limit (H) alarm value, and
this is done using a % value of the maximum span.
᭹ A setting value of 110% indicates that the alarm is
disabled.
[G12: Low Low Alarm] Low-low alarm setting
This parameter sets the low-low limit (LL) alarm
value, and this is done using a % value of the maxi-
mum span.
᭹ A setting value of -110% indicates that the alarm is
disabled.
