Oval Gear Enhanced Electronic Meter
Owner's Manual - Model LM51DN - 1/2"
DESCRIPTION
The model LM51DN electronic lube meter is designed
specifically to dispense motor oils (SAE 5...50), gear oils
(SAE 80...240), automatic transmission fluid, antifreeze
(Ethylene Glycol), brake fluid, windshield wiper fluid,
and engine coolant solutions. Modular design, low cost,
lightweight and rugged make the LM51DN the best choice
for overhead reel systems.
The electronic register module contains a microprocessor
board powered by a lithium battery. It can be programmed
to dispense in pints, quarts, liters, or US gallons and
will totalize in liters or US gallons. The meter calibration
factor is determined during factory test. The meter can
be recalibrated in the field for fluids or different viscosity
if required. A 6-digit liquid crystal display, accurate to the
second decimal place, shows the exact amount of fluid
dispensed. The entire register module is protected from
the wear and tear of normal shop use by a rugged, glass
filled, shock resistant, nylon housing.
OPERATION
As fluid passes through the metering chamber by entering
the inlet port, the internal gears rotate, forcing the fluid
to exit through the outlet port. Each rotation of the gear
displaces a given volume of fluid.
The display shows the amount of fluid dispensed since the
last time the reset button was pushed. Pushing the reset
button will reset the display to zero for the next dispense.

To Program the Scale Factor
1. Press TOTAL three times followed by RESET three times
in a time frame of under 2 seconds. The active unit of
measure symbol will flash when you have entered pro-
gramming mode.
2. Press TOTAL to advance to the first digit of the scale factor.
3. The selected digit will blink. Push RESET to change the
value.
4. When the proper value displays, push TOTAL to move
to the next digit.
5. Continue until the correction factor has been entered.
6. To exit the programming mode, press and hold RESET
and TOTAL simultaneously for 3 seconds.
The display will flash three times and then go blank to indicate
the changes have been saved.
