Fibox 4 & Fibox 4 trace Operation
4.4.1 Temperature Compensation
Use the navigation buttons to move to the Temperature box and select the temperature
compensation mode. With Auto the measurement temperature is determined with the Pt100
sensor. Connect the Pt100 temperature sensor to the respective connector on the transmitter
top panel. Make sure the temperature sensor is in close vicinity to the oxygen sensor or in an
environment with the same temperature as the oxygen sensor. Automatically measured
temperature values can be displayed in °C, °F, or K. Change the settings to the desired unit in
the lower right corner of the
Temperature box.
Select Manual if the temperature at the oxygen sensor during measurement is known and
constant throughout the measurement. Temperature values can be inserted in °C, °F, or K, in
a range from -99 °C to 199 °C. Values will automatically be recalculated in the respective unit.
Switch to the desired temperature unit and change the temperature value in the input field to
the measurement temperature.
4.4.2 Pressure Compensation
Use the navigation buttons to move to the Pressure box. With Auto selected, the integrated
pressure sensor of the Fibox 4 / Fibox 4 trace will measure the atmospheric pressure and
