The current calibration is good.
The stabilization time during calibration expired.
The calibration failed.
The calibration value is above the upper limit.
The cell constant K is out of range for the current calibration.
The reading during calibration was unstable.
The configuration was changed—floating point type.
The configuration was changed—text type.
The configuration was changed—integer value type.
The configuration was reset to the default options.
The power was turned on.
The analog to digital conversion failed (hardware failure).

Start of calibration for conductivity
Resolution
Calibrate the sensor.
Replace the sensor. Reset the Sensor days
counter on the Diagnostics/Test > Reset
menu (or Diagnostics/Test > Counter menu.
Return to calibration.
The outputs will become active after the
selected time period. As an alternative,
remove and then supply power to the
controller.
The value must be between 0 and 4%/°C; 0 to
200 °C.
The temperature is above or below the
temperature range defined by the table.
