Transmitter Calibration
The PC application (Windows or Mac) provides transmitter field calibration. You
can calibrate your transmitter as follows:
Although the UWBT-RH transmitter sensor cannot be field
calibrated, you can replace the RH sensor in the field. The
replacement sensor is Omega part number TH-SP.
Thermocouple Model – UWBT-TC:
This is a 3 point calibration. You need to calibrate the input for K type
thermocouple. You can calibrate the device using 4 different engineering units:
Fahrenheit, Kelvin, Celsius and Rankine. In order to change the engineering units
go to the settings screen, select the engineering unit and click save all settings
button. The following steps show sample calibration of UWBT-TC input using
thermocouple simulator and degrees Celsius as an engineering unit:
• Select K-type thermocouple from the “Sensor Settings” screen
• Select the Low Set Point Temperature option. Set the thermocouple input and
the text box to -96°C. Press the Calibrate button.
• Select the High Set Point Temperature option. Set the thermocouple input and
the text box to 1093 °C. Press the Calibrate button.
• Select the Cold junction Temperature option. Measure the ambient temperature
around the thermocouple cold junction, set the thermocouple input to the measured
temperature and enter the value in the text box. Press the Calibrate button.
The unit is now calibrated for all different types of Thermocouple inputs. You can
always go back to Factory calibration by pressing the Restore Defaults button.
