Description
Temperature sensor parameters.
Sets the temperature unit (°C or °F) applied to all transmitter temperature
parameters and values.
(Temperature Compensation Type)

Manual
The value in this parameter is used for the referenced temperature
compensation during manual temperature compensation mode
(default value 25 °C (77 °F). Manual is the default parameter if a valid
temperature sensor is not recognized at power-up or when a Run TC
Recognition routine is run (see below).

Auto
Enabled when a temperature sensor is provided with the probe (the
calculation is based on the Nernst equation – see Appendix A.3,
page 98).
Auto is the default parameter if a valid temperature sensor is
recognized at power-up or when a Run TC Recognition routine is run.

Auto Solution
Auto Solution temperature compensation can be selected when a
temperature sensor is connected and is recognized by the device.
This selection provides the ability to include a solution coefficient in
the Nernst equation – see Appendix A.3, page 98.
The value in this parameter is used for temperature compensation during
Manual temperature compensation mode.
Adjustable range –20 to 150 °C (–4 to 302 °F). Default = 25 °C (77 °F).
Enabled when Temp Comp Type = Manual.
Adjustable range –10 to 10. Default = 0 pH / 10 °C (50 °F).
Enabled when Temp. Comp Type = Auto Solution.
Adjustable range –20 to 20. Default = 0 mV / 10 °C (50 °F).
Enabled when Temp. Comp Type = Auto Solution.
Indicates the type of integral temperature sensor detected:

Pt100

Pt1000

Balco 3k
Starts the auto-recognition process for the sensor.
Acceptable types for this process are: Pt100 2-wire, Pt100 3-wire, Pt1000
2-wire, Pt1000 3-wire, Balco 2-wire, Balco 3-wire.
Indicates if the temperature sensor was recognized / not recognized, either
during startup or after execution of the Run TC Recognition function, above.
