2. LCD DISPLAY

Page 3of 8
The “LCD” of the meter features two numerical registers and various indications displayed to the users as
below:
INDICATIONS
Partial register (5 figures with moving comma from 0.1 to 99999)
Indicate the volume dispensed since the reset button was last pressed.
Indication of battery charge
Indication of calibration mode
Indication of resetting present total to Zero
Total register
Indication of flow rate mode
Indication of unit of measurement of partial: L= Liters
GAL = Gallons
PT = Pints
QT = Quarts
3. OPERATIONAL BUTTONS
The turbine digital meter features two buttons (MENU and RESET) which individually perform two main
functions and other secondary functions together.
The main functions performed are:

Fig. 3

Page 5of 8
Carefully follow the procedure indicated below.
FORMULA
Example:
Actual value 20.75
Display value 18.96
Current correction factor 1.000
Proper correction factor 1.000×(20.75/18.96)=1.000×1.094=1.094
1
Wait for the meter to go to standby.
2
Reset the resettable total as outlined previously in
Fig. 3.
3
Press the MENU key. Keep it pressed until screen
displays an image similar to the image shown. The
first digit of the top display will flash to indicate the
meter is in correction factor modification mode.
4
Press the RESET key to choose the desired digit
from 0 to 9. Press the MENU key to start the next
digit. Each digit of the correction factor can be
changed individually.
5
Make sure the correction factor is correct, and then
press the MENU key. Keep it pressed until reaching
quit calibration mode; the factor is automatically
saved. The meter returns to standby.
Proper correction factor = current correction factor × (actual value/ display value)

Page 6of 8
MODIFY THE CORRECTION FACTOR IN FIELD
Carefully follow the procedure indicated below.
1
Wait for the meter to go to standby.
2
Reset the resettable total as previously outlined in
Fig. 3.
3
Start dispensing into a measuring glass.
Stop dispensing when over 5 liters of volume is
reached, then check the actual dispensed value. The
volume that is displayed on the LCD is the Display
Value, not the Actual Value, which may be slightly
higher. For example, in the figure on the right, the
Display Value is 18.96 while the Actual Value is
20.75.
4
Press the MENU key. Keep it pressed until the
screen appears similar to the figure on the right, with
a digit flashing in the far left zone. Press the RESET
key to choose the correct digit from 0 to 9. Press the
MENU key to go the next digit and repeat the
process so that the Actual Value can be input.
5
Make sure the correction factor accurate, and then
press the MENU key. Keep it pressed until
calibration is finished and the factor is saved. The
meter will then return to standby.
