The CALYS 150 displays in the window details of the selected configuration using the following icons:
: to show loop power supply off
: to show loop power supply on
: to show square law scale
: to show HART compatibility.
When the values measured are near the lower limit of the range (0 mA or 4 mA) a small variation in the values
measured translates into a more significant variation for the converted values (in %) because of the square law
nature of the scaling.
