OPERATING MODE
Trip function
Total meter
• The meter is fitted with a Total meter which shows the
accumulated the fluid volume released since the meter
was put into operation for the first time. The Total meter
cannot be reset.
• When the meter is in normal status (partial meter) (fig.
10), the Total meter (fig. 13) can be shown by pressing the
SELECT button (fig. 11) twice in a row.
• It is enough to press the SELECT button again (fig. 12) to
return to the partial meter mode (fig. 10).
• The total meter does not take into account the quantities
released during the calibration process.
• The changes in the calibration factor do not affect the
value stored in the total meter.
CALIBRATION
The meter is calibrated in the factory and does not normally
require calibration for the fluids for which is intended (see
technical specifications section). Nevertheless, if using fluids
with high or low viscosity, as well as if working with high
flows or very low flows, calibration may be required.
Calibration may be required after having used the meter
for a long time, especially if working with fluids with dirty
residues. Verify the precision of the meter prior to use and
proceed with calibration if required.

Automatic meter reset
Both the partial meter and the total meter are reset to zero
when reaching the value 99999.

In order to perform the calibration process correctly the
following rules must be adhered to:
1. The calibration can be performed for any volume,
however it is recommended for a minimum of 1 litre. As
a maximum 25 litres can be used.
2. The container used must be calibrated and be completely
empty (prior use of the container can easily leave
behind 0,1 l even if it seems empty). Put the container
upside down for a while, or clean it before starting the
calibration process.
If you would like a truly accurate calibration, you must
use precision scales and know the density of the fluid.
With the density data the volume to be released is
converted (ahem.: 1, 2, 3 ... litres) to mass units.
3. When the fluid is being released you must wait until all
the air contained in it is eliminated. This can take some
time. If precision scales are used the accumulation of air
has no effect.
