Calibration of Analog Output:
Follow the following steps to calibrate the analog output against the end device
1. Go to the calibration menu, select analog output, and then select method. Full calibration will
cause the flow computer to output the minimum possible signal 4 mA. Enter the live output
value reading in the end device i.e. 4 mA and click OK button. Now the flow computer will
output full scale 20 mA. Enter the live output i.e. 20 then click OK button.
2. Now verify the output against the calibration device .
Multi-Variable Transmitters (Model 205)
– DP and Pressure
Calibrations are performed under

. . Select inputs to be calibrated, and then select full,
single, offset calibration method.

1. Induce live value for pressure or DP.
2. Select Multivariable DP or pressure.
3. Select offset calibration method, enter offset, and click OK button.
4. Now read induce live values to verify the calibration.

1. Induce live value for pressure or DP.
2. Select Multivariable DP or pressure
3. Select full calibration method
4. Induce the low range signal, enter the first point, and then click OK button.
5. Induce the high range signal, enter the second point, and then click OK button.
6. Now verify the live reading against the flow computer reading .

1. Select Multivariable DP or pressure
2. Select Reset calibration method
3. Now verify the live reading against the flow computer reading
While doing calibration before downloading any of the calibrated values, it is a good practice to verify that
the SFC332L close reading to the induced value.
The DP reading must be re-calibrated for the zero offset after applying line pressure.
