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 ON/RESET and SELECT
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 SELECT button (fig. 17) successively until displaying the
required unit (fig. 18).
Press ON/RESET (fig. 19) to start the calibration process (fig. 20).

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 ON/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 ON/RESET
button increases the value by 0.1 litres and each press of the
SELECT button (fig. 24) reduces this value by 0.1 litres (fig. 25).

Once the real value released is set (fig. 25) press the ON/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 SELECT
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.
