SAFETY
IMPROPER GROUNDING, POOR VENTILATION, OPEN FLAMES OR SPARKS CAN CAUSE A HAZARDOUS CONDITION AND
RESULT IN AN EXPLOSION OR FIRE AND CAUSE SERIOUS INJURY.
• Be sure the fluid system is properly grounded. See your pump instruction manual for details.
• If there is static sparking or if you feel an electric shock while using the meter, stop dispensing immediately. Identify and
correct the problem before continuing.
• Provide fresh air ventilation. This will avoid the buildup of fumes from the fluid being dispensed.
• Do not smoke while dispensing flammable fluids.
• Keep the dispensing area free of debris including solvents, rags and spilled gasoline.

Meter Installation
METER INSTALLATION
Relieve System Pressure
THIS EQUIPMENT STAYS PRESSURIZED UNTIL THE PRESSURE IS MANUALLY RELIEVED.
1. Turn o the power supply to the pump or close the shuto valve.
2. Dispense any uid in the system into a waste container by opening the meter.
3. Open all bleed-type master air valves and uid meter in the system.
4. Leave the meter open until ready to pressurize the system.
To reduce the risk of injury from fluid spray from the meter, follow this procedure when you:
• Are instructed to relieve pressure.
• Stop dispensing.
• Check, clean or service any system equipment.
• Clean or install nozzles.
Grounding
MOVEMENT OF FLUIDS THROUGH THE DISPENSING SYSTEM CREATES STATIC ELECTRICITY. STATIC ELECTRICITY CAN
CAUSE VOLATILE FUMES RESULTING IN AN EXPLOSION AND FIRE. THE DISPENSING SYSTEM MUST BE GROUNDED.
Grounding reduces the risk of static sparking. Ground all system components according to local, state and federal codes.
Consult the pump user manual and other system components to ground the following:
• Pump: follow manufacturer's recommendations
• Air and Fluid Hoses: use only grounded hoses
• Air Compressor: follow manufacturers recommendations
• Fluid Supply Container: follow the local code
Flushing Procedure
IF THIS INSTALLATION IS NEW OR IF THE FLUID IN THE LINES IS CONTAMINATED, FLUSH THE SYSTEM BEFORE
INSTALLING THE METER(S).
OTE:N If the system has multiple dispense positions, begin at the position farthest from the pump and move towards
the pump.
1. Close uid dispense valves at every position.
2. Once the main uid outlet valve at the pump is closed and the air pressure to the pump motor is properly adjusted, the air
valve is opened.
3. Slowly open the main uid valve.
4. Place the hose end in a waste container. Make sure the hose is secure so no uid leaks during ushing.
5. Slowly open the dispense valve and allow enough uid to pass through it to ensure that the system is clean.
6. Close the valve and repeat for all dispense positions.

Meter Installation
3. Tighten completely with an open ended, adjustable, wrench. See Figure 4.
Figure 4: Use wrench to tighten
OTE:N The threaded end of the meter always has female threads. The metal end of the hose must have male threads. The
inlet and outlet swivel connections are either 1/2" NPT or 1/2" BSPP, depending on meter model.
Attach Nozzle to Meter
1. On the opposite end, apply Loctite® 243 sealant, or equivalent, to the end of the nozzle. Thread the nozzle onto the meter.
See Figure 5.
2. Screw it in tightly with an open-ended, adjustable, wrench. See Figure 6.

English units. See "Change Unit of Measure" on page 11.
OTAL to display Accumulated Total, after holding for three seconds the display changes to
Figure 9: Re-settable total display
Emergency Override
In case of an emergency or to interrupt a batch, the meter is equipped with an Emergency Override which closes the valve,
immediately stopping fluid flow.
1. Press O to activate the Emergency Override.
2. After an Emergency Override, batching can continue by pulling up on the trigger.
Error Codes
The meter has one error code that may display:
SF0 (Scale Factor 0) The Scale Factor setting for the meter is set to 0.000.
The code provides an indication, at the meter, that there is an error in communication between the meter and keypad. To
correct the error, input a valid Scale Factor for the meter follow the instructions in "Change Scale Factor" on page 11. All other
error codes are for factory purposes only. To clear the meter, press RESET.
SERVICE
Low Battery
When the batteries need to be changed a progression of warnings appears on the meter screen. First, the Low Battery icon will
appear on the display, this means that the batteries are getting low, and should be changed. When the icon begins to flash,
the battery power is too low, and meter functions are disabled.

Calculate Scale Factor
CALCULATE SCALE FACTOR
A Scale Factor is a number used to adjust meter accuracy. The Scale Factor is set at the factory using motor oil with a viscosity
of 10W. The primary use for Scale Factor recalibration is to batch fluids with different viscosities. If the fluid has a lower
viscosity, more fluid can slip past the meter gears without being detected. Changing the Scale Factor adjusts the meter to
compensate for the loss. The meter multiplies each pulse by the Scale Factor number to correct the accuracy when it converts
to the specified units. For an approximate Scale Factor for fluids of different viscosities, see "Chart of Approximate Scale Factors"
on page 13.
OTE:N The meter’s original Scale Factor was written on the trigger when it was calibrated at the factory. It may have been
revised after field installation. Use the Scale Factor showing on the display, not on the trigger.
CHANGING THE SCALE FACTOR WILL CHANGE THE ACCURACY OF THE METER, POTENTIALLY CAUSING IT TO OVERFILL
OR UNDER FILL. THIS HAS THE POTENTIAL TO CAUSE A MECHANICAL BREAKDOWN.
To view the current scale factor, press and hold TOTAL and AUTO simultaneously.
Absolute Scale Factor
For absolute scale factor, preform this test:
1. Run a measured amount of uid through the meter.
2. If the meter delivers 4.20 quarts and the display shows only 4.00 quarts, then the Scale Factor needs to be adjusted.
3. Divide what the meter delivered (4.20) by what the display shows (4.00). You get an error factor of (1.05).
4. The existing Scale Factor is 1.0123, as shown in steps 1 and 2 in "Verify Changes".
5. To calculate a new factor: 1.0123 (existing Scale Factor) x 1.05 (error factor) = 1.0629 (new Scale Factor).
6. Enter that number as described in the "Change Scale Factor" on page 11.
OTE:N Use the Scale Factor shown on the display, not on the trigger.
