Operation
Never operate the meter with the black plastic
cover removed. The cover protects the meter from
damage due to impact. Meters are factory sealed
to keep moisture and dirt out. See the
Service
section before you service the meter.
CAUTION
To prevent line contamination, which can cause
equipment malfunction or damage, flush the lines
before you install this equipment in the system.
CAUTION
To Activate the Digital Display
Press the
RESET
key pad to clear the meter before
starting a new dispense cycle. This is the best way to
activate the meter, because it also clears the quantity
of the last dispense cycle.
The digital display can also be activated by pressing
the
TOTAL
key pad or by running fluid through the
meter. See Fig. 2.
NOTE:
The digital display of the meter goes blank
after approximately two minutes of non-use.
Function of TOTAL
When the digital display is blank, press and release the
TOTAL
key pad to display the quantity of the last
dispense cycle. See Fig. 3.
To see the accumulated total of fluid dispensed
through the meter, press and hold the
TOTAL
key pad.
The accumulated total is shown in gallons for the
gallon/quart/pint meter, and in liters for liter meter. The
meter can accumulate a running total of up to 19,999
gallons (or liters) dispensed before returning to zero.
See Fig. 4.
Function of RESET
Press the
RESET
key pad to clear the quantity of the
last dispense cycle and return the digital display to all
zeros. See Fig. 2.
To Change the Measurement Units
(gallon/quart/pint meter only)
The meter is factory-set to dispense in quarts. To
change the measurement units, press and hold the
RESET
key pad until the measurement unit on the
right side of the digital display is flashing. Then press
the
TOTAL
key pad until the desired measurement unit
is shown. Release both key pads. See Fig. 5.
To be sure the proper amount of fluid is dispensed,
always use the same measurement unit for a
particular fluid.Units should be changed only by
authorized employees.
CAUTION
To Verify the Accuracy of an Electronic
Meter
1.
Use a clean, calibrated container. If using a single
container, be sure to clean it after each dispense.
2.
Have pump air pressure at the lowest possible
setting for dispensing fluid.
3.
Put the tip of the nozzle at the bottom of the
calibrated container.
4.
If the tip of the dispense valve does not reach the
bottom of the calibrated container, use a length of
plastic tubing over the tip of the nozzle to ensure
liquid enters the container from the bottom.
5.
Trigger the gun slowly so the fluid immediately
covers the tip of the dispense valve.
6.
Dispense 1 quart of fluid according to the metered
display on the dispense valve.
7.
Allow product to sit for 20 minutes, then compare
the actual, physical measurement in the calibrated
container to the measurement displayed on the
meter.
NOTE:
The procedure above will determine if the
meter is accurately dispensing the product and mini-
mize testing errors. Some variance may occur depend-
ing on the viscosity of the fluid. If this procedure deter-
mines that the meter is not accurate, recalibrate the
meter as described in the service manual or replace
the meter or the electronics as necessary.
