In addition to the above parameters, please note further parameters from function

!
To ensure correct flow rate calculation, you must enter the precise inside diameter of the meter in
coordinate GB-55 (nominal diameter). You can find this information in the annex to the verification
certificate. From software version 1.5 upwards, this value can no longer be found in GB-55, but has
to be entered in GA-08 (pipe diameter).
In IGM mode, there are three polynomials for correction:
GM Reynolds number correction,
GN base correction,
GO error curve linearization.
All the other polynomials and interpolation point methods are switched off. The parameters are
calculated in the factory.
