b� If the meter registered less than
the quantity in the container, turn
the calibration screw clockwise�
If the meter registered more
t h a n t h e a m o u n t i n t h e
container, turn the calibration
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 nylon washer and calibra-
tion screw cover�
The meter’s strainer should be cleaned
at regular intervals, especially when low
flow is detected.
Clean or Replace Strainer
1� Remove the nuts and bolts at the
inlet fitting� Remove the fitting,
O-ring, and strainer�
2�
Using a fine brush, clean the
strainer� Replace the strainer as
necessary�
3� Wipe clean the inlet, housing, and

The large meter display represents the
Batch Total for each fuel delivery� Before
dispensing, reset the Batch Total to zero
by turning the knob. (Figure 3)
The small display represents the
Cumulative Total of all fuel deliveries
and cannot be reset�
CALIBRATION
The meter is accurately calibrated at
the factory for use with kerosene grade
(JET A)
� Due to differences in viscosity
and flowrates, the meter may require
recalibration to measure other fuels or
to adjust for inaccuracies�
1� Purge air from the meter and fuel
system by dispensing fuel into a
container until a full flow occurs.
Close the nozzle�
2� Reset the meter counter to zero by
turning the reset knob. (Figure 3)
3� Pump into 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 flow rate is
used� When topping off the calibra-
tion 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
meter 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 nylon washer. (Figure 4)
