6.4  Parameter Description
IMPORTANT
One output can be selected from pulse, alarm, or 
status through the parameter setting.
(1)  Menu B: Easy Setup items
Those parameters with a high frequency of use 
have been grouped together in Easy Setup. All 
basic functions can be controlled using only the 
parameters from this block. Parameters from 
Menu B share identical names with those from 
othermenus;however,modicationofonesuch
parameter will result in the other being automatically 
modied.
[B10: Language] Selection of language used for 
the display unit 
→ This setting is linked with that of parameter H30.
One of the following languages can be selected for 
the display unit.

[B20: Flow Damping] Setting of the damping time 
constant 
→ This setting is linked with that of parameter C11.
Thedampingtimeconstantshouldbemodiedto
suppressanoutputuctuationortochangethe
response time. This time constant has an effect 
onanalogoutputandontheowratedisplay(i.e.,
actualinstantaneousowrate,%,currentvalue),
and in addition, it also affects pulse output and 
totalization. However, when “No Damping” has 
been set for J25:T/PDampSelect, there will be no 
effect on pulse output or totalization.
*:  Time constant: The time required for the output to reach 
63.2% from 0%.
NOTE
When the damping time is short, the output 
uctuates.Setthetimeto5secondsormorefor
control loop.
