3.1.1. To begin calibrating the injection
pump, press the Select Key from the
home screen to open the Main Menu
3.1.2. Navigate to the Calibration Menu and
press the Select Key
3.1.3. Select the Injection Pump Calibration
Menu
3.1.4. To calibrate, follow the directions
displayed. The verometer level
should be filled to approximately 50%
before
starting the calibration
procedure. The verometer level is
displayed for reference. If the
verometer level is lower, return to the
Home Screen and manually begin a
verometer fill by pressing the Left
Arrow Key. The fill process will stop
automatically.
3.1.5. Return to the injection pump calibration screen. When opening this menu, the ACC
position will adjust to the 100% capacity position and can be seen on the micrometer
between the ACC and injection pump.
Wait for the ACC to cease adjusting before
starting the calibration procedure.
3.1.6. Using the navigation keys, navigate to the Pipeline Pressure and enter the typical
pipeline pressure. Press the Select Key to enter the value.
3.1.7. Navigate to the Start Calibration icon at the bottom of the screen. Press the Select
Key to start the calibration procedure. The injection pump will inject odorant against
the current back pressure for 30 to 40 seconds and calculate the Max Pump Capacity.
Once calibration is complete, select the Apply Calibration button, and the Calibrated
indicator box will be filled with a check mark. The Max Pump Capacity value will be
mirrored to the Odorization Parameters menu for easy reference.
3.2 - Analog Flow Input Calibration, 1-5 VDC / 4-20 mA
Important: Many factors affect the signal between the signal source and the
NJEX ZEO system. Elements of the signal electrical system such as the gauge
and length of the wire, isolation barrier, grounding, transient voltages, and the
condition of the signal generated by the flow device can affect the signal and how that
signal is received by the NJEX System. To truly calibrate the NJEX System to the signal,
use only the flow equipment that will be part of the odorization system such as a flow
computer, RTU, PLC, pulse index drive, or differential pressure transducer
.
3.2.1. To begin calibrating the analog flow input, press the Select Key from the home screen
to open the Main Menu
3.2.2. Navigate to the Calibration Menu and press the Select Key
3.2.3. Select the Flow Signal Menu
