Figure 6-7. Thermocouple Model Calibration
RTD Model – UWBT-RTD:
This is a two point calibration. You can calibrate the device using 4 different
engineering units: Fahrenheit, Kelvin, Celsius and Rankine. Below example uses
degrees Celsius as an Engineering unit. In order to change the engineering units
go to the settings screen, select the engineering unit and click save all settings
button. You need to calibrate the input for a Pt100 European curve. Using a
precision decade box:
• Select Pt100 and European Curve from the “Sensor Settings” screen
• Select the Low Set Point Temperature option. Set the decade box to 48
Ω
and
the text box to -130°C. Press the Calibrate button.
• Select the High Set Point Temperature option. Set the decade box to 389
Ω
and
the text box to 845°C. Press the Calibrate button.
To calibrate for a PT1000 RTD European Curve, using a precision decade box:
• Select Pt1000 and European Curve from the “Sensor Settings” screen.
• Select the Low Set Point Temperature option. Set the decade box to 480
Ω
and
the text box to -130°C. Press the Calibrate button.
• Select the High Set Point Temperature option. Set the decade box to 3890
Ω
and the text box to 845°C. Press the Calibrate button
The unit is now calibrated for all different types of RTD inputs. You can always
go back to Factory calibration by pressing the Restore Defaults button.
