PV V & I Scales Factors “S”
This command returns the floating-point conversion constant for the PV voltage
and current inputs for the specified gain codes. There is a different conversion
constant for each gain code. The integer values returned by the DS-Tracer for
the PV voltage and current values are multiplied by these constants to convert
these values to engineering units. The constants are returned in IEEE single
precision (32 bit) binary format.
Format
“S,n1,n2”
n1 = Voltage gain code 0,1,2, or 3.
n2 = Current gain code 0,1,2, or 3.
Gain Codes
0 = 1
1 = 10
2 = 100
3 = 1000
IEEE 32 bit floating point format:
1 sign bit, 8 bit signed exponent, 23(+1) bit mantissa.
Refer to IEEE documentation for more details.
Example
command “S,0,1”
