INSTRUCTION NAME: AINSQR (analog input square root)
DESCRIPTION: This instruction sets the SVA output equal to the square root of the value, in
engineering units, of the analog input at the channel specified by operand 1. The engineering units
used to convert the input are specified by values in operand 2. The square root operation retains
the sign of the analog input value after taking the square root of the analog input. The low
engineering units value can have a suppressed or elevated value. For example, this allow
bi-directional flow and elevated flow measurements. In an elevated flow measurement, the range
may be from 500 GPM (4 mA) to 1000 GPM (20 mA). In a bi-directional flow measurement, the
engineering units range from -200 GPM (4 mA) to 400 GPM (20 mA). Note that the use of this
function depends upon the hardware configuration.
The SVD output is 0 if the analog input value is between -2 and 102 percent of span. If the analog
input value is outside this range, the SVD output is 1.
