3.2 Calibration of the measuring system
If the HDA eco has been installed in a TECALEMIT pump system and/or a dispensing
station, a calibration of the entire system has already been performed at the factory.
If a different flow meter is installed, calibration should be performed.
Only by doing so can it be ensured that the pulses generated by the flow meter are
processed correctly by the HDA eco, and that the measurement and display results
correspond to the volume dispensed.
The following steps have to succeed for the calibration:
Step 1:
Enter the pulse value of the used flow meter as in sector 0 is described. If the exact
value is unknown it can be estimated
Step 2:
Make a delivery into a satisfactorily accurate vessel or undertaken by means of a ref-
erence meter.
Step 3:
The pulse value is calculated as follows:

Example:
A 20 litre measurement vessel is filled; the meter only indicates 19,7 litres. The old
pulse value is 53,95. The new pulse value is calculated as follows:

Step 4:
As last step enter the pulse valuenew as in sector 0 described.
When the last step is succeeded, the measuring system is calibrated.
