CALIBRATION
CALIBRATION CAPACITY
After the calibration process you will obtain precision within the
range of ±0.5% with the meter. If the meter exceeds this range it
could be due to the following:
• Unsuitable container used for the calibration.

CALIBRATION PROCEDURES

The calibration process is semi-automatic. To start the process, the
meter must be in partial meter mode (fig. 14) and is accessed by
simultaneously pressing the buttons RESET and TOTAL/TRIP for
3 seconds (fig. 15). After releasing the buttons the current
calibration factor is shown on the meter (fig. 16).

If the screen does not show the correct measuring unit (fig. 16)
press the TOTAL/TRIP button (fig. 17) successively until displaying
the required unit (fig. 18).
Press RESET (fig. 19) to start the calibration process (fig. 20).
TOTAL / TRIP

It now starts to release the desired volume into the container.
Remember that you must release at least 1 litre to perform a good
calibration. In the example shown in the figures it is assumed that
2 litres are released according to the reading on the calibrated
container and that the meter records 2.1 litres (fig. 21).

• The container is not empty before the calibration.
• Air in the fluid which has not been completely removed.
• The values are not properly introduced into the calibration
process.
To administer the real quantity released (which is that measured in
the calibrated container or scales), press the RESET button for 1
second (fig. 22). The digits start to flash (fig. 23) indicating that the
value shown can be modified. Each press of the RESET button
increases the value by 0.1 litres and each press of the TOTAL/
TRIP button (fig. 24) reduces this value by 0.1 litres (fig. 25).

Once the real value released is set (fig. 25) press the RESET
button for 1 second (fig. 26). The meter shows the new stored
calibration factor (fig. 27) and then exits the calibration process.
The screen shows the partial meter with the units set during the
calibration process (fig. 28).
If, during any phase of the calibration process, you wish to exit
without saving the changes made you must press the TOTAL/TRIP
button for 1 second. Likewise, if 30 seconds of inactivity elapse
during the process, the meter switches off automatically and exits
the calibration process without storing the data.
