D.2 CALIBRATING BY PERCENTAGES
This second example, shown below,
demonstrates that it is also possible to
calibrate your outputs as a percentage. For
instance, you may wish to read directly values
that may be scaled from 0 to 1200. Your voltage
span is scaled from 1 to 5 volts so the range is
approximately 4 Volts. Thus, 1200 divided by 4
equals 300 units per volt. If you equate the
difference as a percentage, the midpoint in
units equals 600, or approximately 3 volts.
With this information in mind, you want to set
zero units equal to 1.00 V and 1200 units to
5.00 V and let the software adjust the span as
you calibrate.
This example assumes that an analog output
channel needs to calibrated to a span of 0 to
1200.
