METER OVERVIEW
The Electronic Preset Meter RF2 (EPM RF2) is equipped with RF (radio frequency)
communications to communicate with a uid management system keypad to get authoriza-
tion and dispense information. This is referred to in the manual as the RF Mode.
The meter can also be run as a standard EPM. This is referred to in the manual as the EPM
Mode. This is intended for start-up purposes or when the uid management system is not in
use.
Once a work order has been entered at the keypad, the operator simply pushes the button
on the meter to start communications between the meter and the keypad. The meter
receives authorization from the keypad to unlock and the dispense batch quantity. When
the trigger is pulled the pre-set dispense batch quantity dispenses.
The meter automatically shuts off when the dispense batch quantity has been reached.
A “Top Off” feature allows additional uid to be dispensed and tracked after the batch quan-
tity has been dispensed.
Upon completion of the dispense, the operator presses the button. The meter then
locks, prohibiting any unauthorized dispense of uid and the dispense quantity is sent to
the keypad.
Meter Buttons
Used to enter the dispense Batch quantity when in
the EPM Mode. These buttons are NOT used in RF

METER INSTALLATION
Relieve System Pressure
1. Turn off the power supply to the pump
or close the shutoff valve.
2. Dispense any uid in the system into a
waste container by opening the
meter(s).
3. Open all bleed-type master air valves
and uid meter(s) in the system.
4. Leave the meter(s) open until ready to
pressurize the system.
Grounding
1. Grounding reduces the risk of static
sparking. Ground all system components
according to local, state, and federal
codes. Consult the pump user’s manual
and other system components to ground
the following:
2. Pump: follow manufacturer’s
recommendations
3. Air and Fluid Hoses: use only grounded
hoses
4. Air Compressor: follow manufacturers
recommendations
5. Fluid Supply Container: follow the local
code
Pressurized Equipment
This equipment stays pressurized until the
pressure is manually relieved. To reduce the
risk of injury from uid spray from the meter
follow the Pressure Relief Procedures when
you:
• Are instructed to relieve pressure
• Stop dispensing
• Check, clean, or service any system
equipment
• Clean or install nozzles
Explosion and Fire
Movement of uids through the dispensing
system creates static electricity. Static
electricity can cause volatile fumes result-
ing in an explosion and re. The dispensing
system must be grounded.

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 uids with different viscosities.
If the uid has a lower viscosity, more uid 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 specied units. The reading is then always correct.
For an approximate Scale Factor for uids of different viscosities, consult the charts on the
next page.
NOTE: The meter’s original Scale Factor was written on the trigger when it was calibrated
at the factory. It may have been revised after eld installation. Use the Scale Factor show-
ing on the display, not on the trigger.
Changing the Scale Factor changes the accuracy of the meter, potentially causing it to
overll or under ll. This has the potential to cause a mechanical breakdown.
To view the current Scale Factor:
1. Press and hold the button and the button at the same time.
Absolute Scale Factor
For absolute Scale Factor, perform 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 “To view the current
Scale Factor”, above.
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 section of this manual.
NOTE: Use the Scale Factor showing on the display, not on the trigger.
