Calculate the content of your hydrochloric acid in g/L:
RS1=EP1*C01*C02/C00
End point*conc.(titrant)*molecular weight/sample size
To correct a formula, delete it with <CLEAR>.
• Confirm the formula with <ENTER>.
• You may enter a text for the result output, see page
8.
• Enter the desired number of decimal places for the
result.
• Select the desired unit g/L with <SELECT>, or type
a text as unit, see page 8.
The Titrino prompts for the calculation of the next result.
Quit the formula entry by pressing <QUIT> twice.
In order to be able to calculate the result, enter the calculation constants used in the for-
mula.

<ENTER>
• Press <C-FMLA>.
The constants which have been used in the formula
are requested: input with digit keys, confirm with
<ENTER>.
C01: Concentration of your titrant= 0.1 mol/L.
Enter 0.1.
C02: Molar mass of HCl = 36.47 g/mol
Enter 36.47.
Now only the constant C00 is missing to perform the calculation. This constant is re-
served for the sample size. It can be entered directly.
