Abs. MC Deviation 1...8 (MassConcAbsDev)
Absolute deviation of the mass concentration
ρ
s
in g/L with automatic calculated prefixes.
Rel. MC Deviation 1...8 (MassConcRelDev)
Relative deviation of the mass concentration
ρ
s
in
%.
Final Result 1...15 (FinalResult)
Identification of the final result.
Result Value 1...15 (ResValue)
Numerical quantity of the related final result. The
unit is specified in
Result Unit
. The final results
are calculated according to the page
"
CALCU-
LATION
"
of the 746 VA Trace Analyzer. If no for-
mulae have been entered no final results are cal-
culated.
Result Unit 1...15 (Meas. Unit)
Result unit of the related final result.
Abs. Result Deviation 1...15 (ResAbsDev)
Absolute deviation of the related final result. The
unit is specified in "
Result Unit
“.
Rel Result Deviation 1...15 (ResRelDev)
Relative deviation of the related final result in %.
Comment 1...15 (Comment)
Comment on any error or difficulty in the evalua-
tion of the final result.
Note: Depending on the entered formula on page "CALCULA-
TION" of the 746 VA Trace Analyzer the quantity in final results is
treated in two different ways:
1. The defined
Res.unit
starts with "
#
“ as first character. The
transmitted result unit begins with an automatically calculated
prefix. When storing the numerical value for the
Result Value
and the
Abs. Result Dev.
to the database this prefix is taken
into account and the
Result Unit
is stored without prefix. So
selections with different magnitudes in the concentration
range are carried out correctly.
2. The defined result unit starts with any alphabetical character
as first character. The
Result unit
is stored unchanged. The
numerical values for the
Result Value
and the
Abs. Result Dev.
are also stored without further calculation.
We recommend to use only units with automatic prefix calculation
which means that they must have a "
#
" as first character.
For more detailed information about the different fields we refer to
the user manual of the 746 VA Trace Analyzer.
