1. Select which output type to be calibrated; mA or Voltage
2. This will prompt a warning to verify calibration wants to be
done, click Next.
3. Enter in low reading from input device that FAC is being
calibrated to (Figure 14)
a. Ex. If EDGE is being calibrated to a multimeter,
enter in reading from multimeter to Current

7. Calibration is now complete
Linearizer
The linearizer function is designed to correct for
devices that will vary in a nonlinear way as a device
changes in flow/frequency. It can take nonlinear input
and change it to a more linear analog output.
Ex. Looking at a meter that has a range of 0.5-2 GPM. If at
0.5 GPM (=100HZ) it has a K-factor of 1800, at 1.5 GPM
(=200Hz) it has a K-factor of 1850, and at 2.0 GPM
(=300Hz) it has a K-factor of 1900. Using a linearizer would
ensure the most accurate results over the full range of flow.
To access the Linearizer Table, click on the Setup tab,
followed by Linearizer Table. This will bring up the
table as pictured (Figure 15). Enable the linearizer
function by clicking the Enable Linearizer box at the bottom left of the window. The values in
the table cannot be modified. Rows can only be Added or Removed to change the table.
