Before Putting Into Operation - Mato DIGIMET E35 Mode D'emploi

Operating Instructions / English

1. Before putting into operation

Please check that the technical data of the installation match with those of the lube meter, for example
connections, pressure, flow range and medium. Once the meter has been installed, please make sure
that no air, pressure shocks or particles can damage the meter. Please check all connections to
leakage. After the installation we recommend to do several transactions into an approved tank. Should
the use of different oil viscosities show discrepancies by the error limit, this can immediately be
corrected at the site. This avoids to remove or exchange the meter. In case of pretested meters can
corrections be carried out by technicians or officials of the National Weights and Measure Laboratory.
2. Details of unit operation
2.1 Battery
The battery is exchangeable in all meters of the DIGIMET E35 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: Lithium CR 123A. A battery symbol is warning when battery change is necessary.
2.2 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.
2.3 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 pus-
hed 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.
2.4 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.
