Instrument variables
The following instrument variables can be used in formulae:
C## Common variable C01...C18 from the working
memory (see section 5.4.5). The common vari-
ables can be used to exchange results between
different determinations.
ED:<subst>:<V> Difference of the mean values of the evaluation
quantities (I.delta, P.delta or t.delta) for the
specified substance <subst> and variation <V>.
The numeric value put out refers to the basic
unit A, W or s.
ES:<subst>:<V> Standard deviation of evaluation quantities
(Std.dev.) for the specified substance <subst>
and variation <V>. The numeric value put out
refers to the basic unit A, W or s.
EU:<subst>:<V> Mean value of peak voltages (U) or half-wave
voltages (U/2) for the specified substance
<subst> and variation <V>. The numeric value
put out refers to the basic unit V.
EV:<subst>:<V> Mean value of evaluation quantities (I.mean,
P.mean or t.mean) for the specified substance
<subst> and variation <V>. The numeric value
put out refers to the basic unit A, W or s.
MA:<subst> Standard addition mass (Add.mass) for the
specified substance <subst>. The numeric
value put out refers to the basic unit g.
MC:<subst> Mass concentration ρ
s
(Mass conc.) for the
specified substance <subst>. The numeric
value put out refers to the basic unit g/L.
MD:<subst> Total scatter (MC.dev.) of mass concentration ρ
s
for the specified substance <subst>. The nu-
meric value put out refers to the basic unit g/L.
ML:<subst> Scatter due to calibration (Cal.dev.) of mass
concentration ρ
s
for the specified substance
<subst>. The numeric value put out refers to the
basic unit g/L.
MS:<subst> Substance mass (Mass) in the measuring vessel
for the specified substance <subst>. The nu-
meric value put out refers to the basic unit g.
KD:<subst> Mean scatter (Mean deviat.) for calibration and
standard addition curve of the specified sub-
stance <subst>. The numeric value put out re-
fers to the basic unit A, W or s.
KN:<subst> Non-linearity factor (Nonlin.) for calibration and
standard addition curve of the specified sub-
stance <subst>. The numeric value put out re-
fers to the basic unit [AL/g]
