3 VA Database Table

VA Database 2.0

Abs. MC Deviation 1...8 (MassConcAbsDev)

Absolute deviation of the mass concentration

in g/L with automatic calculated prefixes.

Rel. MC Deviation 1...8 (MassConcRelDev)

Relative deviation of the mass concentration

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
