Description
(Temperature Compensation Type)
Manual temperature compensation is enabled when the device does not
detect any temperature sensor connection either at power-up or upon
execution of Run TC Recognition. When Temp Comp Type is Manual, the
user configurable Manual Temp value is used for temperature compensation.
Enabled when a temperature sensor is provided with the probe (the
calculation is based on the Nernst equation – see Appendix A.3, page 98).
Enabled when a temperature sensor is detected by the device either at
power-up or when executing the Run TC Recognition routine is run (see
page 64).
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.
Adjustable range –20 to 20. Default = 0 mV / 10 °C (50 °F).
Enabled when Temp. Comp. Type = Auto.
