6. PARAMETER DESCRIPTION
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
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% and setting for the
current (4 to 20mA) output low cut is made using a
percentage of the smallest flow rate span. However, the
low cut function will be terminated if this parameter 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.
Example: Situation where low limit is set to 10%
F0655.EPS
4mA
Output
Input
5.6mA(10%)
NOTE
If “2.4mA or less” has been set for G21:4-20mA
Alarm Out, 2.4mA or less will be output upon an
alarm occurrence, regardless of the low limit
setting.
NOTE
If the setting value for the low limit is not less
than the high limit value (as set using J12: 4-
20mA High Lmt), the setting alarm “4-20 Lmt
Err” will be displayed.
This parameter has no effect on pulse output
or the totalization function.
[J12: 4-20mA High Lmt] Setting of the high limit
for current output
This parameter is used to restrict high current portions
of current (4 to 20mA) output, and it is initially set to
120%. Setting should be performed when a lower value
is required for the higher limit.
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 high limit is set to 90%
F0656.EPS
4mA
Output
Input
18.4mA(90%)
NOTE
If “21.6mA or more” has been set for G21:4-20
mA Alarm Out, 21.6mA or more will be output
upon an alarm occurrence, regardless of the
high limit setting.
