3.12 Temperature and Pressure Parameter Values
All parameters that indicate a temperature or pressure can be expressed in degrees Celsius/bar or
Fahrenheit/PSI, according to parameter Ec41 that sets the unit of measurement.
Modifying the Ec41 parameter from Celsius/bar to Fahrenheit/PSI and vice versa does not involve
an automatic update of the parameters from one unit of measurement to the other. Therefore, the
operator must check all the parameters concerning temperature and pressure in order to modify them
accordingly.
In particular, by modifying the Ec41 parameter from °C/bar to °F/PSI:
• the value of the temperature and pressure parameters are multiplied by 10 (with no
decimal).
Modifying the Ec41 parameter from °F/PSI to °C/bar:
• the value of the temperature and pressure parameters are divided by 10 (with a decimal).
When the instrument is switched on, the parameters are verified and modified if they are out of
the specified range of values.
