3. From the list, highlight a free, as yet undefined formula. :Off
is shown after free formulae in the list.
4. Press Edit.
5. Enter the formula for the calculation of the amount, see
below.
The Result (for example in mg/L) is listed under Select Cn.
The amount is found under Abs Variables.
6. During execution of the methods you will be asked to enter
the amount and the result is calculated accordingly.
7. Press OK to confirm.
8. Once the formula has been entered, define the unit,
designation, upper and lower limit and display of the formula
as done previously for C1.
9. Once all necessary formulae have been defined, press
Done.
Please note the following for the input of amounts and calculation
of the end result:
Enter the following formula to calculate the weight-specific result:
C
x
= (C
(mg/L result)
x 10) / C
y(amount)
Amount: in g/100 mL
If during the analysis there is a prompt to enter the amount of the
sample, enter the value in g/100 mL.
The concentration of the displayed result will then be
g analyte/100 g amount.
Note: The analyte is dissolved in 100 mL. The test result is first
established as a concentration in mg/L. The result is based on a volume
of 1 liter by a factor of 10/amount and the result expressed as a
concentration in g/100 g.
