cuvette temperature.
Call service if error
continue
Reset error manually
ELECTRODE SLOPE
Service state
The error occurs if the
electrode slope is not
in the range of -50mV
to -70mV
Change membrane
and electrolyte, if there
is still a problem, check
standards,
measurement range
and chemistry, check
flow rate. If all OK, but
error still present, fit
new electrode
Reset error manually
FALSE ELEC DATA
Service state
The mV value for Zero
related to Standard 1 is
not within the allowed
range.
Allowed range for
(Uzero-UStandard1)
depending on
measurement range:
Low (0.05 to 20 mg):
5mV to 200mV
Medium (1 to 100 mg):
20mV to 265mV
High (10 to 1000 mg):
50mV to 315mV
Check cleaning
solution (level and
delivery) and sample
delivery, check
Standard 1 (level and if
correct for
measurement range),
change membrane and
elektrolyte. Error may
occure when sample
has very unusual
properties. In this case
the error can be
switched to "OFF" in
the configuration
menue.

Service state
Drain is blocked
(lime?)
Check drain line. Adapt
cleaning interval to
water hardness.
Reset error manually
SAMPLE1 / SAMPLE2
Continued
measurement
the amount of sample
is not sufficient
(channel1 / channel2)
This occurs as error if
SAMPLE DETECTION
is set to ERROR
Check sample delivery,
make sure that sample
line has no negative
pressure, check
tightness of piston
pump, check overflow
and air valve, check
tightness of system.
Automatic reset when
enough sample is
available or manuell
reset
