●
The temperature display is blinking.
The temperature display does not change from 25ºC.
The temperature measurement exceeds the
measurement range.
Measurement range: -10 – 100.0ºC
Cause How to solve problem
The temperature
of the sample
solution
exceeds the
measurement
range. Check the temperature of the
sample solution and change to a
sample solution that has a
temperature within the
measurement range.
The thermistor
connection
within the
electrode is
severed or
shorted. Measure the resistance of the
temperature sensor connector. If it
is 50 k
Ω
or more at room
temperature, replace the electrode.
The electrode
connector is not
attached
properly. Attach the electrode connector
properly, so that the O-ring on the
temperature connector disappears
from sight.
The main unit of
the meter may
be defective. In Temperature Display Calibration
mode (See “
●
Temperature zero
adjustment [item No. 02]” page 46),
check whether or not the “Minus”
display appears, regardless of
whether or not there is a tempera-
ture connector.
There is a
problem with the
setting for the
temperature
display
calibration mode
(see page 46). Initialize the settings (see page 49).
