The Analog Output arrived at above should be a number from 0000-4095 which
drives a D/A converter for a 4 - 20 mAmp and a 0 - 5 volt output on Pins 7 and 8 of the 9
Pin connector. Therefore the gain factor can be estimated by re-arranging the analog
output equation as follows:
GAIN = (512)(Analog Out)
Variable Value
If the desired max output of the system is achieved at 5V or 20 mAmp - this is equivalent
to an Analog Out value of 4095 and the above equation would read:
GAIN = (512)(4095)
Variable Value
The "Variable Value" is the true flow rate or volume capability of the system
measured at the analog value discussed above and will therefore depend upon the
ANALOG RULE selected. The Analog Rule is discussed further on the next page.
NOTE: The value entered ignores the decimal point position.
For Example:
In Ratio Mode (06)
If Ideal Ratio = 5.00...........................................................................Variable Value = 500
If Ideal Ratio = 10.00.........................................................................Variable Value = 1000
In Flow Mode (00-02)
If Flow Rate = 80.0 cc/m ..................................................................Variable Value = 800
" " " = 200.0 cc/m ......................................................................Variable Value = 2000
" " " = 5.25 GPM .......................................................................Variable Value = 525
In Flow Mode (03-05)
If Total Flow = 10.00 Gal.................................................................Variable Value = 1000
