6. PARAMETER DESCRIPTION
[G45: Alm Record3] Alarm record3
This parameter is used to display the third most-recent
alarm, and the alarms that can be displayed are the
same as those for G41: Alm Record1.
[G46: Alm Record Time3] Display the operation
time of alarm record3
This parameter is used to display the operation time at
which the alarm indicated by G45: Alm Record3
was occurred. For example, “1D23:45” indicates that
an alarm was occured at the operation time of 1 day,
23 hours, and 45 minutes.
[G47: Alm Record4] Alarm record4
This parameter is used to display the fourth most-
recent alarm, and the alarms that can be displayed are
the same as those for G41: Alm Record1.
[G48: Alm Record Time4] Display the operation
time of alarm record4
This parameter is used to display the operation time at
which the alarm indicated by G47: Alm Record4
was occurred. For example, “1D23:45” indicates that
an alarm was occured at the operation time of 1 day,
23 hours, and 45 minutes.
(7) Menu H: Display Setting items
Menu H contains setting items relevant to the display
unit.
[H10: Display Select1] Setting of the first line for
display unit
→ Refer to the description for parameter B40
This parameter selects the display content of the first
line for display unit.
[H11: Display Select2] Setting of the second line
for display unit
→ Refer to the description for parameter B41
This parameter selects the display content of the
second line for display unit.
[H12: Display Select3] Setting of the third line for
display unit
→ Refer to the description for parameter B42
This parameter selects the display content of the third
line for display unit.
[H20: Display Cycle] Setting of the display cycle
This parameter sets the cycle for the display-response
speed of display unit. Settings should be made in
accordance with the measurement environment by, for
example, setting a longer display cycle when using the
equipment in low temperatures.
[H30: Language] Selection of language used for the
display unit
→ Refer to the description for parameter B10
This parameter can be used to select the language for
the display unit.
(8) Menu J: Auxiliary Function Setting items
Menu J contains setting items such as the flow direc-
tion, rate limits, and current output limits.
[J10: 4-20mA Low Cut] Setting of the low-cut range
for current output
This parameter is used to force current output to 0%
(i.e., 4mA) in the vicinity of 0% output, and setting for
the current (4 to 20 mA) output low cut is made using
a percentage of the smallest flow rate span. However,
the low cut function will be terminated if this param-
eter is set to 0%.
The indications of the instantaneous flow rates (%,
Actual instantaneous flow rate, mA, Bar graph) on the
display unit are the same action.
Example: Situation where low cut is set to 10%

[J11: 4-20mA Low Lmt] Setting of the low limit for
current output
This parameter is used to restrict low current portions
of current (4 to 20mA) output, and it is initially set to
-20%. Setting should be performed when a higher
value is required for the lower limit.
The indications of the instantaneous flow rates (%,
Actual instantaneous flow rate, mA, Bar graph) on the
display unit are the same action.
