Table 4 Warning list for conductivity sensors (continued)
Warning Description Resolution
TEMP TOO HIGH The measured temperature is >
200 °C Make sure that the sensor is
configured for the correct
temperature element.
TEMP TOO LOW The measured temperature is <
-20 °C
CAL OVERDUE The Cal Reminder time has expired Calibrate the sensor.
NOT CALIBRATED The sensor has not been calibrated Calibrate the sensor.
REPLACE SENSOR The sensor has been in operation >
365 days Calibrate the sensor with a
reference solution and reset the
sensor days. Refer to
Sensor
diagnostic and test menu
on page 19. If the calibration fails,
call technical support.
CAL IN PROGRESS A calibration was started but not
completed Return to calibration.
OUTPUTS ON HOLD During calibration, the outputs were
set to hold for a selected time. The outputs will become active after
the selected time period.
WRONG LINEAR TC The user-defined linear temperature
compensation is out of range The value must be between 0 and
4%/°C; 0 to 200 °C.
WRONG TC TABLE The user-defined temperature
compensation table is out of range The temperature is above or below
the temperature range defined by
the table.
WRNG USER CONC TABLE The concentration measurement is
outside of the range of the user
table Make sure that the user table is set
for the correct measurement range.
WRNG BLT-IN TEMP TABLE The measured temperature is
outside of the range of the built-in
temperature compensation table Make sure that the temperature
compensation is configured
correctly.
WRNG BLT-IN CONC TABLE The concentration measurement is
outside of the range of the built-in
concentration table Make sure that the concentration
measurement is configured for the
correct chemical and range.
