Measuring
1 Select the measuring method (see section 7.4.1).
2 Prepare two standard calibration solutions.
3 Perform a two-point calibration according to user
guidance.
4 As soon as a stable value for the second standard
calibration solution is reached, the
display indicator
h
stops flashing. The slope (mV) of
the electrode is displayed after the two-point
calibration. The probe symbol shows the electrode
evaluation after the two-point calibration.
5 Start the measurement with [Start] .
The entry for Standard volume , Standard
concentration and ISA volume opens.
6 Enter Standard volume , Standard concentration and
ISA volume with
82
and [Next] .
7 Thoroughly rinse the electrode with deionized water.
8 Immerse the electrode in the standard solution.
