Auto: In automatic temperature compensation, the analyzer meas-
ures the temperature using an RTD (resistance temperature device)
in the sensor. The analyzer then uses the measured temperature to
calculate the membrane permeability correction and oxygen solubili-
ty factor.
Manual: In manual temperature compensation, the analyzer uses the
temperature entered by the user to calculate the membrane perme-
ability correction and oxygen solubility factor. It does NOT use the
actual process temperature. Do NOT use manual temperature com-
pensation unless the difference between the calibration and meas-
urement temperatures is less than 2°C.
Manual temperature compensation is useful if the sensor RTD
has failed and a replacement sensor is not available.
If Manual temperature compensation is selected, be sure to enter the
desired temperature.
