Cause
Solution
Reset warning
Warming up
Instrument is warming
up sample tubing after
start (de-frosting)
If there is a risk that
the sample tubes are
frozen, a warning is
displayed
As far as possible, wait
until end of the
warm-up phase
(except if certain there
is no frost), to cancel
place instrument in
Maintenance mode
and start the
measurement again
Automatic
Cooling down
Fan 100 % , standstill
until cool enough
Instrument is cooling
down after start using
ventilation, if it was
heated excessively
Wait until instrument
has cooled down
enough
Reset, automatically
as soon as cool
Analyzer is too cold.
Measurement
Interior of instrument is
cooler than 15 °C
(59 °F)
Close instrument door,
if necessary check
heating
Reset, automatically
as soon as warmer
Analyzer is too hot.
Measurement, but no
more air cleaning
At very high internal
temperature, the air
cleaning of the filter
modules is disabled so
as to generate less
heat. internal temp =
target temp of cuvette
Change/clean air filter,
check air ducts for
blockage, check
enclosure fan, is
ambient temperature
allowed? If necessary
increase electrode
temperature
Reset, automatically
as soon as cool
Cuvette is too cool.
Continued
measurement
The cuvette is not
being heated
adequately 2 min after
sample change:
temp. = ((target temp.
of cuvette) –1 °C
(34 °F))
Close instrument door,
check/fit cuvette
insulation. Attention: If
this warning occurs
during the calibration,
there is a risk of
incorrect
measurements, for this
reason close door
during calibration!
Automatic
Electrode slope
Continued
measurement
The warning occurs if
the electrode slope is
not in the range of
–55mV to –67mV
Change membrane
and electrolyte, if there
is still a problem, check
standards and
chemistry, check flow
rate. If all OK, but
warning still present, fit
new electrode
Automatic
Filter modules are
contaminated
Continued
measurement
Filter modules soiled
Clean filter modules
soon
Automatic
Maintenance mode
Maintenance mode
The instrument is in
the Maintenance mode
or is switching to this
state
–
Automatic when the
Maintenance mode is
left
Reagent level
Continued
measurement
Amount of reagent has
dropped below
warning level set
Check reagent level
and replace if
necessary, then reset
reagent level. The
level is indicated
mathematically and
can only function
reliably if the counter is
only reset when the
solution is changed
