6.3.2 Remedies for error codes
When an error code is displayed, take necessary actions in accordance with the table below.
Error code Causes or possibilities Remedies
E-21
(Temperature
sensor
disconnected)
Resistance error between T and T of the
sensor.
The sensor is defective when the resistance value
is within the range of 1 kΩ to 1.3 kΩ.
Replace it with a new one.
Wrong wiring of the sensor cable or junction
cable
Check if the wiring is open between T and T.
E-22
(Temperature
sensor short-circuit)
Resistance error between T and T of the
sensor
Refer to the section on E-21.
Wrong wiring of the sensor cable or junction
cable
Check if the wiring is short-circuited between T
and T.
E-23
(Out of temperature
compensation
range error)
Measured liquid temperature error
(110°C or more)
Lower the temperature of the measured liquid to
within the working temperature range of the
sensor.
Resistance error between T and T of the
sensor
Refer to the section on E-21.
E-24
(Out of temperature
compensation
range error)
Measured liquid temperature error
(0°C or less)
Lower the temperature of the measured liquid to
within the working temperature range of the
sensor.
Resistance error between T and T of the
sensor
Refer to the section on E-21.
E-90
E-91
E-92
(System error)
System error in the instrument
Turn the power OFF and turn it ON again.
If the system error persists even after restarting
the instrument, contact
HORIBA Advanced
Techn o

AdoF
Improper setting for temperature
compensation
Check the parameters related to the cell constant
and temperature compensation. Especially check
to see if whether the calculation method for
temperature compensation has been set to “PurE”
for the measurement range other than 2
µS/cm.
(When the deionized water characteristics has
been set for solutions other than deionized water,
measurements cannot be made correctly.)
