Resolution
Make sure that the display format is set for
the correct measurement range.
Make sure that the sensor is configured for
the correct cell constant.
Make sure that the sensor is held in air during
zero calibration and is not located near radio
frequency or electromagnetic interference.
Make sure that the cable is shielded by metal
conduit.
Make sure that the sensor is configured for
the correct temperature element.
Calibrate the sensor.
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.
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.
Make sure that the user table is set for the
correct measurement range.
Make sure that the temperature
compensation is configured correctly.
Make sure that the concentration
measurement is configured for the correct
chemical and range.
