Square-root Computation of PVs
The square-root function is used in the case such as when the differential pressure
signal of a restriction flowmeter such as an orifice or a nozzle is converted to a flow
signal. You can also set the low-signal cutoff point for the square-root computation.
Square-root computation ON/OFF setting: ON or OFF (the initial value is 1.0%)
Selectable range of the low-signal cutoff of the analog input: 0.0 to 5.0% (the initial value
is OFF)

PV Range Conversion (only during loop control with PV switching)
The PV range conversion is a function used to determine the PV range of the control
function when the measurement range of the two input signal is different for the loop
control with PV switching. For example, if the input range of the first input is 0 °C to 500
°C and the input range of the second input is 300 °C to 1000 °C, the PV range
conversion is used to convert the PV range of the control function to 0 °C to 1000 °C.
