3. Fill a graduated calibration container to a
specified quantity. For the greatest
accuracy, be sure the container is placed on
a level surface and a consistent flowrate is
used. When topping off the calibration
container, use a quick-open and quick-close
method until the mark is reached.
4. Compare the meter display to the quantity
in the container. If the display does not
register the quantity on the container, adjust
the meter by performing the following:
a. Gain access to the recessed calibration
screw by turning the calibration screw cover
and seal counterclockwise. Remove the
cover and seal. (Figure 5)
b. If the meter registered less than the
quantity in the container, turn the calibration
screw clockwise. If the meter display read
more than the amount in the container,
turn the screw counterclockwise.
5. Empty the calibration container and repeat
steps 2 to 4 until the meter registers the
quantity in the container.
6. Install the calibration screw cover and seal.
