9.1 Battery

The battery is exchangeable in all meters of the LM OG-A series while
opening the cover on the front of the register. A new programmation is
not necessary as the programmation does not get lost. Battery type of
approved meter LM OG-A: Lithium CR ½ AA
A battery symbol is warning when battery change is necessary.

9.2 RESET

The display of the batch register memory can be put to ZERO by pushing the RESET
button. A reset is not possible during a batch process. Resetting of the totalizer is
only possible through internal programming.

9.3 Interruption of batch process

By releasing the meter trigger, the batch process is interrupted. When pulled again,
the batch process will be continued at the very point where it was interrupted, unless
the RESET button has been pushed in the meantime. The display will remain
unchanged during the interruption. If the batch process is interrupted by external
source – e. g. failure of a transfer pump – the procedure is the same.

9.4 Functional control

In normal operation, the register board totalizes flow in the lube meter by sensing
reed switch actions, as described below. The batch display may be reset to zero by
momentarily pressing the RESET button on the front panel. This action will set the
batch accumulator to zero and cause the register to enter a selftest mode, as
described below. For the self test, it is necessary that the display is activated with all
numerics set to "8" and all other indicators set to "on" for a period of 0,8 seconds. If
flow or reed switch action takes place during the self test period, the resultant pulses
are processed as normal flow accumulations. This accumulation of flow can only be
reset by pressing the RESET button, or by reprogramming the register for a different
unit of measure. During the self test period, the meter will compare the double
redundant storage of the correction factor, the unit of measure and direction of
rotation. If two or more values do not correspond, the register will show a series of
dashes (- - - -) and will become inoperative.
If flow sensing or reed switch action is present at any time and it is not preceded by a
pressing of the RESET button, the flow accumulations will be added to the value
already present in the batch accumulator.

9.5 Totalizer (LM OG-A)

Pressing the TOTAL button will cause the accumulator memory value to be displayed,
for as long as the button is being pressed, but only as long as no volume pulses are
coming in (see also calibration or correction factor). The factory programmed
correction factor results from accuracy testing of bare meter with the mounted
electronic register:
