Tube 16-bit Integer Register Usage Notes:
1.
Primary Element Mask: 1=Orifice Square Root
2.
Calculation Method Mask: 2=AGA-3 1985, 4=AGA-3 1992; The sum of these values (6)
indicates 2 and 4 are valid choices.
3.
Super-Compressibility Method Mask: 1=NX19 with FIXED FT AND FP VALUES, 2=NX19 AUTO,
4=NX19 GRAVITY CO2 & N2, 8=NX19 CO2 & N2 & C1, 2048=AGA8 Gross, 4096=AGA8
Detail. The sum of these values (6159) indicates all of the choices listed above are valid.
