Analog data AnA
Analog full
scale
AF
Depends on the
type of product.
3600
• Analog full scale flowrate
(Unit: [ r /h])
• Setting range: 0.01 to 99999
Ex.: To change the analog output full scale
flowrate (flowrate to produce a 20mA
output) from 3600L/h to 1800L/h
→
Set to
"AF 1800"
(L/h).
Analog
damping
AdAn .5 0.0
• Analog time constant (soft)
(Unit: [sec])
• Setting range: 0.01 to 99999
If analog output has high ripples, select
a larger AdAn to stabilize the indicated
reading.
Ex.: To change the analog output time const.
from 2.5 [sec] to [5 sec]
→
Set to "AdAn 5.0."
4mA trim A04 ————— (4.000) Analog output 4mA trim
For details, see "Parameter Setup
Procedure".
20mA trim A0 ————— (20.00) Analog output 20mA trim
For details, see "Parameter Setup
Procedure".
Pulse data PuLSE
Pulse width Pon 30
Factored pulse output
"ON" duration
(Unit: [msec]) Ex.: To change pulse width from 1 ms to
50ms
→
Set to "Pon 50" (msec).
(Note 4)
Pulse
Dummy
output 1
Pd
Not a parameter to
be set up
————
Furnishes a 1Hz simulated
factored pulse output irrespective
of flowmetering. • This function is useful in loop check, etc.
• For operation in practice, see "About
Dummy Output Functions (special
features)".
Pulse dummy
output 2
Pd
Not a parameter to
be set up
————
Furnishes a 10Hz simulated
factored pulse output irrespective
of flowmetering.
NOTES 1. When it is desired to change meter factor (F) and conversion factor (H), select the proper unit that matches the indicated unit (Un)
for each.
2. When meter factor (F) and conversion factor (H) have been changed, data, such as pulse, analog, and alarm parameters, must
also be changed to the proper units relative to the conversion.
3. Be sure to set up a value such that F

H/ ≦ Pu ≦ F

0000.
4. Be sure to set a value such that factored pulse "OFF" width > 1 ms.
5. Setting of meter factor (F) includes frequency division (1/10) by hardware means.
