8.15 Flow Amount Integration Function
(3) Concept of unit scaling
Unit scaling adjusts the number of digits of the integrated flow amount by multiplying "instantaneous flow amount
× T/T" by a multiple of 10.
Set the unit scaling to store the value after the decimal point of "instantaneous flow amount × T/T" in CH
Integrated flow amount (Un\G1332 to Un\G1339).
When the value of "instantaneous flow amount × T/T" is 123.45
By setting 100 as a unit scaling, the value of "instantaneous flow amount × T/T" turns 12345 and the value after
the decimal point can be stored in CH Integrated flow amount (Un\G1332 to Un\G1339).
The following table lists the indications of the calculated value of T/T acquired by the combination of CH Flow
amount time unit setting (Un\G1316 to Un\G1319) and CH Integration cycle setting (Un\G1308 to Un\G1311)
and the value set in CH Unit scaling setting (Un\G1324 to Un\G1327).
