Create reagent
1.
Enter the Reagents window.
2.
Press 5 then 1.
3.
Press
✓ in the New reagent menu.
4.
Select From = Other.
The option From = Catalogue allows you to create a reagent
from a list of commonly used reagents.
5.
In the ID field, enter the reagent name (up to 14 alphanumeric
characters). It is advised to enter the chemical formula of the rea-
gent (example: HCl). The concentration is entered on the next
line.
6.
Enter the "approximate" titre of the reagent (5 characters) in the
Target titre field.
7.
Enter the unit indicated on the reagent bottle (mM = mmol/l, M =
mol/l, mN = meq/l or N = eq/l).
8.
Press 1 twice to create the reagent.
9.
Enter the reagent parameters.
Current value
This is the current sent to the Pt-Pt socket on the Titration Manager.
This parameter is available if mV(i>0) has been selected for
Measurement in the Edit method or Edit reagent menus.
Enter in:
Method parameters menu
Reagent parameters menu
Range available:
-1000 to +1000 µA in steps of 1 µA
Curve
Select if you want to print the pH/mV = f(volume) titration curve at the
end of each test.
