(1) Err1 Temperature compensation computation value out of range
Cause:
When the standard temperature conversion is made to conductivity at 25
؇C, this
instrument performs temperature compensation computation based on the preset
temperature coefficient.
Err1 is displayed in cases where temperature compensation computation is impossible
because the preset temperature coefficient is improper or a solution with a large
temperature coefficient is measured at temperatures lower or higher than 25
؇C.
Corrective action:
* Reset the temperature coefficient to the correct value.
* Measure solution at about 25
؇C.
(2) Err2 Out of temperature measurement range
Cause:
This error occurs if the measurement liquid temperature is outside the range -10 to
120
؇C, or if sensor cables are disconnected.
Note: The liquid temperature should never be outside the range 0 to 80
؇C.
Corrective action:
* Set the liquid temperature to 0 to 80
؇C.
* Replace the sensor. (Refer to Sec. 1.6)
