CALIBRATION PROCEDURE
The flow rates on your pumps can be calibrated in situ in order to take the specific characteristics of the
installation into account, such as the actual operating pressure, the product to be dosed, the stroke setting, etc.
The
cc
stored in memory during calibration are used for displaying the
ml/min
.
Three calibration modes can be used: Automatic, Manual, and Default.
WARNING:
When the calibration function is accessed the equipment is reconfigured as follows:
The strokes and impulses recorded in 1:n, n:1, and 1:c modes with the
memory function active, are zeroed
External impulses coming from the counter are not managed and so the
calculation of the frequency of external impulses is zeroed. On exiting
calibration the first impulse will be handled as the start of a new series of
impulses.
While in any operating mode, from the display mode (pump ready to dose) the Calibration menu can be accessed
as follows:
- Push
the
Cal
key and hold it down. Cal appears on the screen for a few seconds, and
then the main calibration menu will open (
ml/min
icon flashing).

Select the relevant calibration mode using the

key.

Automatic Mode (Aut) (see Fig. 29)
To carry out calibration a capacity graduated container is required of a resolution that is adequate for the
presumed flow rate of the pump in its working conditions. Indicative values can be found in
Table 1
.
Having selected “Aut” mode, push the Cal key to activate the preset strokes, which will be done at maximum
frequency.
Once the strokes have been completed the display will show the cc value for the previous calibration or the
default setting. Use the
▲
or
▼
keys to set the quantity of product dosed during calibration in
cc
. This value
can be set between 0,1 and 999,9 cc.
Press the
Cal
key to save the settings and to return to display mode. The pump returns to its status before
calibration.
