CALIBRATION Through DOS Program
Analog Input 4-20mA or 1-5 volt signal:
Calibrations are performed under
I/O | Calibration
. Use the arrow keys to scroll to
Calibration
and press < ENTER> . After you press < ENTER> the screen should show
COMMUNICATION STATUS:OK
.

For simple offset type calibration simply induce the signal into the analog input and make sure the flow
computer is reading it. After you verify that the flow computer recognized the analog input press <F8>.
The screen will freeze. Scroll down to the analog input you are calibrating and enter the correct mA
reading. Then press <
ENTER> followed by <F3> to download. The screen will stay in the freeze mode. To
bring the live readings press <F2> and then the flow computer will display the new calibrated readings.
The offset type calibration is mainly used when a small offset adjustment needs to be changed in the full-
scale reading. The offset will apply to the zero and span.

To perform full calibration be prepared to induce zero and span type signal.
1. Induce the low end signal i.e. 4mA in the analog input.
2. Press <F8> and scroll down to the reading then press <ALT><R>(alternate key and the letter
R simultaneously). Then immediately enter the analog input value i.e. 4mA. Follow that by
<
ENTER>
and pressing the <F3> function key to download data.
3. Now be ready to enter the full-scale value. Simply induce the analog signal and then enter
the value i.e. 20mA, and then download by pressing <
ENTER>
then <F3> function key.
4. Induce live values to verify the calibration .
