10
Add the standard solution to the sample.
11
Start the measurement with
g
.
When the measurement is finished an entry window appears.
The info line indicates the current setting for the ion sensitive
electrode [e.g. Ag (ISE)] and the ion to be subtracted.
12
Using
82
and
g
, enter the values for the volume of the
standard solution (
Std. volume
) and concentration of the stan-
dard solution (
Std. concentration
).
13
If the info line indicates an incorrect selection for the ion sensi-
tive electrode [e.g. Ag (ISE)] and the ion to be subtracted [e.g.
Ag (Sub)]:
Select
Ion specification
with
82
and confirm with
g
.
An entry window appears to define the ions.
