With the exception of the first and last value (Vb and Menu), this list is user-specific, i.e.
the user can himself set which values in this list are displayed. Ex-works, these are the
above-mentioned values some of which are also displayed in anothe r list and described in
the corresponding chapters.
The setting of the values to be displayed occurs by using the parameterisation software
WinPADS.
Vb
Volume at base conditions (pre-decimal places)
The volume at base conditions computed from the measured "actual volume" is
summed here provided no alarm is present.
An alarm is present when any message with the number "1" or "2" is urgent
(® 3.8).
Vb = Vm ž C
The post-decimal places of Vb are displayed in the standard volume list (® 3.2).
Vm
Actual volume
p

Values which are also displayed in another list and described in the corresponding
chapters.
Z
Compressibility factor
Zb
Compressibility factor at base conditions
The computation of z and zb occurs according to S-Gerg-88, AGA-8 GC methode
1 or 2, AGA-NX19 or AGA-NX19 acc. Herning and Wolowsky, depending on the
setting of Md.K. The gas analysis values Ho.b, CO2, H2 and N2 and Rhob (Md.K
= 1) need to be included in the entries for this ( ® 3.6).
