The Lumax Electronic Flow Meter features a menu with which the user can select as the main unit measurement: Quarts (Qts), Pints (Pts), Litres (Lit) or Gallons (Gal). The combination of the unit of
measurement of the Partial register and that of the Totals is predefined according to the following table:

Maintenance:
The Lumax Electronic Flow Meter has been designed to require a
minimum amount of maintenance. The only maintenance required are the following:
1. Battery Change
2. Cleaning of the Turbine
1. Battery Replacement:
The Lumax Electronic Flow Meter comes complete with
2 x 1.5 V. Alkaline Batteries (Size AAA). Lumax Electronic Flow Meter features
two low-battery alarm levels:
a.
When the battery charge falls below the first level on the LCD, the fixed battery symbol appears. In this condition,
Flow Meter continues to operate correctly, but the fixed icon warns the user that it is advisable to change the batteries.
b.
If Flow Meter operation continues without changing the batteries, the second battery alarm level will be reached
which will prevent operation. In this condition the battery icon starts to flash and is the only icon that remains
visible on the LCD. To change the Batteries, with reference to the exploded diagram positions, proceed as follows:
• Press RESET to update all the totals
• Loosen the 4 screws on the back cover
• Remove the old Batteries
• Place the new batteries in the same position as the old ones
• Close the cover again, by positioning the rubber protection as a gasket
• Flow Meter will switch on automatically and normal operation can be resumed.
The Flow Meter will display the same Reset Total, the same Total and the same Partial indicated before the Batteries were changed.
After changing the Batteries, the meter does not need calibrating again.
Malfunctions
4. Direct modification of K Factor:
This procedure is especially useful to correct a “mean error” obtainable on the basis of several performed dispensing operations. If normal Flow Meter operation
shows a mean percentage error, this can be corrected by applying to the currently used calibration factor a correction of the same percentage. In this case, the percentage correction of the “USER” K
Factor must be calculated by the operator in the following way:
New K Factor = Old K Factor x (100 - E%)
100
If the meter indicates less than the real dispensed value (negative error) the new calibration factor must be higher than the
old one as shown in the example. The opposite applies if the meter shows more than the real dispensed value (positive error).

Example:

- 0.9 %
Current Calibration Factor
1,000
New “USER” K Factor
1,000 * [(100 – ( - 0,9))/100]=
1,000 * [(100 + 0,9)/100] = 1.009
Action Display
6 SHORT/LONG CAL KEY KEYING
The indicated value changes in the direction indicated by the arrow:
- one unit for every short “MENU” key keying
- continually if the “MENU” key is kept pressed. The speed
increase rises by keeping the key pressed. If the desired
value is exceeded, repeat the operations from point (5).
7 LONG RESET KEY KEYING
Flow Meter is informed that the calibration procedure is
finished. Before performing this operation, make sure
the indicated value is that required.
8 NO OPERATION
At the end of the calculation, the new “USER” K Factor is shown for
a few seconds, after which the restart cycle is repeated to finally
achieve standby condition.
Attention:
From now on, the indicated
factor will become the calibration factor used by the meter and will
continue to remain such even after a battery change.
9. NO OPERATION
The Flow Meter stores the new work calibration factor and
is ready to begin dispensing, using the “USER” K Factor
that has just been calculated.

2 LONG “CAL” KEY KEYING
Flow Meter enters calibration mode, shows “CAL” and displays the
Calibration Factor being used instead of the Partial. The words
“Fact” and “USER” indicate which of the two Factors (factory or user)
is currently being used.
3
LONG RESET KEY KEYING
Flow Meter shows “CAL” and the Partial at zero. Flow Meter is ready
to perform on-site calibration by dispensing.
4
LONG RESET KEY KEYING
We now go on to Direct change of the calibration factor:The word
“Direct” appears together with the Currently used Calibration Factor.
In the bottom left part of the display, an arrow appears (upwards or
downwards) defining the direction (increase or decrease) of change
of the displayed value when subsequent operations 5 or 6 are performed.
5
SHORT RESET KEY KEYING
Arrow direction changes. The operation can be
repeated to alternate the direction of the arrow.

Problem
LCD: No indication contact
Precision Measurement not enough
Reduced or Zero Flow Rate
The meter does not count, but the Flow Rate is correct
Possible Cause
Bad Battery
Wrong K Factor
The meter works below minimum acceptable Flow Rate
Turbine Blocked
Incorrect Installation of Gears after Cleaning
Possible Electronic Card issues
Corrective Action
Check Battery Contacts
Check the K Factor according to the Instructions
Increase the Flow Rate until an acceptable Flow Rate range has been achieved
Clean the Turbine
Repeat the Reassembly Procedure
Contact your Dealer
WARNING!:
Do not discard the old batteries in the environment.
Refer to local disposal regulations.
2. Cleaning:
Only one operation is necessary to clean the Flow Meter.
After removing Flow Meter from the plant where it was
built in, any residual elements can be removed by
washing or mechanically-handling. If this operation
does not restore a smooth rotation of the turbine, it will
have to be replaced.
WARNING!:
Do not use compressed air onto the turbine in order to
avoid its damage because of an excessive rotation

To choose between the 4 available combinations:
• Wait for Flow Meter to go to Standby
• Press the “MENU” and “RESET” keys together and hold for five seconds. The current unit of measure will
begin to flash. Press “RESET” to chose a different unit of measure, then press MENU to confirm.
• Flow Meter will pass through the start cycle and will then be ready to dispense in the set units.
Note:
The Reset table Total and Total registers will be automatically changed to the new unit of
measurement. NO new calibration is required after changing the Unit of Measurement.
