Calibration - Grundfos DME 2 Notice D'installation Et D'entretien

6. Calibration

It is important that the pump is calibrated after instal-
lation to ensure that the correct value (gph, ml/h or
l/h) appears in the display.
The calibration can be carried out in three different
ways:
• Direct calibration (recommended).
The dosed quantity of 100 strokes is measured
directly. See section 6.1.
• Indirect calibration.
A calibration factor selected from a table is used
for the specific installation. This method can be
used if it is not possible to carry out a direct cali-
bration. Indirect calibration will never be as accu-
rate as direct calibration. See section 6.2.
• Check calibration. See section 6.3.
