Remarks
Example: Given meter factor 9.918mL/P
(=9.918
×
10
−
3[L/P])
→
Set to "F9.9180
−
3" (L/P).
To convert total flow and instant. flowrate units
to units other than L. (Normally H1.0000E0
unless unit conversion takes place.)
Example: at 1.5kg per 1L, to convert the
flowrate to read in kg
→
Conversion factor is 1.5 [kg/L] (=1.5000
×
1000[kg/L]; Set to "H1.5000E0" [kg/L]. (Note 1)
Example: To change factored pulse weight to
10L/P (=1.00
×
10
+1
[L/P]
→
Set to "Pu 1.00E1" (L/P). (Note 2)
By changing Un, units that appear on LCD
can be changed. (This is a change in
indicated units; it by no means influences flow
calculation.)
Example: To show instantaneous flowrate to
0.1 L/h (
＝
one place below decimal point)
→
Set to "bP .1".
Example: To show total flow to 0.01L (
＝
two
places below decimal point)
→
Set to "SP .2".
If no flowrate pulse arrives during At [sec],
instantaneous flowrate is 0.
Instantaneous flowrate is determined by
timing the incoming flowrate pulses for A
times. If dispersion in instant. flowrate
indicated is too great, choosing a greater A
eases the problem.
Example: To obtain factored pulse width of
100ms
→
Set to "Pon 100" (ms). (Note 4)
NOTES: 1. If conversion factor (H) has been changed, pulse weight (Pu), indicated unit (Un) and other related factors need to be changed
relative to the modified unit of registration.
2. Set up such that

3. Default setting At = 9 only for meter size 49.
4. Be sure to set up a value such that factored pulse "OFF" duration > 1 ms.
5. Model without remote signal output (M\model suffix codex-400A) has parameters "Pu " and "Pon" set to 1.00E0 and 1, respectively.
