S/IMPEDANCES Menu

Define the lower and upper limits of the electrode
impedances for the default detection. They should
be defined experimentally .
FREQ. : permits to define the impedance
measurement frequency (limits :
0,1 H to 24 H).
GLASS
Permits an impedance measurement.
The glass electrode impedance measurement is
compensated at 25°C.
REFERENCE
Permits an impedance measurement.
LOWER : defines the lower limit for the
impedance measurement. This limit
is used for the alarm system and
the bargraph DISP4.
UPPER : defines the upper limit for the
impedance measurement. This limit
is used for the alarm system and
the bargraph DISP4.
TEST
Visualizes the impedance measurement value.
