5. CALIBRATION
There exist 2 different types of calibration.
5.1. FACTORY CALIBRATION
The factory calibration is set in the instrument.

Calibrated flow
tube
1000
1000 l/h
Master leak
1000 l/h
Note: this calibration does not take into account tube lengths, seal jig restrictions, ...
5.2. MANUAL CALIBRATION
It is possible that the unit the instrument is delivered in or some external elements
(seals, pipes...) result in the factory calibration being unsatisfactory.
In this case a manual calibration taking into account the previously stated elements, can
be carried out by the operator. For this calibration, the calibrated master leak should be
used in the same conditions as the parts to be measured (diameter, length of the pipes).
