10. Programming and use of LM OG-A (CND)
LM OG-A (CND)
The units of measure and the correction factor can be programmed. A
momentary contact programming button is located on the bottom of the
register, which is accessible only when the register has been removed
from the meter. Removing the register from the meter requires the
removal of a sealed register mounting screw. This seal has to be
restamped by the Office of Weights and Measures. Activating the
programming button (by pressing it for 3 seconds) will immediately
force the register into the program mode. Any reed switch activity during the program
mode will cause the register to exit from the program mode.
Programming procedure LM OG-A (CND)
a) Upon initial activation of the board mounted program button, the register
will display for example:
- Correction factor = 1,0000 LM OG
- Unit of measure L
The programmable correction factor has a range of 0,0000 to 9,9999. The decimal
point is always located after the first digit. When “litres” is programmed or selected as
the unit of measure, the decimal point will immediately change to a comma and will
remain so as long as “litres” is the selected or programmed unit of measure. (Default
values are 0,0000, “clockwise” and “QT”, if no values have been programmed
previously).
b) The unit of measure indicator in the display will immediately begin flashing at 0,3
second rate, all other display action being constant, indicating that the unit of
measure is available for change. With each depression of the RESET button, the unit
of measure indicator will step through its individual four values in sequence, which are
(QT) – GAL – L – PT.
c) Depressing the TOTAL button will store the presently displayed data as the current
value for the new setting.
d) Any depression of the RESET button will increment the first or left most digit of the
correction factor. Depressing the TOTAL button will store the presently displayed
value as the current value.
e) This depression of the TOTAL button in step d) will initiate flashing action of the next
successive digit in the correction factor and allow it to be scrolled with the RESET
button. All other digits will remain constant. This successive programming action will
be continued for the remaining four digits of the correction factor. The four right most
digits of the correction factor will be allowed to assume the full range of values from
zero (0) to nine (9). Each depression of the TOTAL button will store the value present
on the display as the current value for that digit.
f) Successive depressions of the TOTAL button will continue to enable flashing and
scrolling of the digits or unit of measure in sequence. The action will continue even if
a particular unit of measure or correction digit has already been selected by a
previous action.
g) If no scrolling by the RESET button is undertaken between depressions of the TOTAL
button, then the present value of a digit or unit of measure as displayed will be utilized
as the current value for the digit or unit of measure.
