NB: If it is not possible to carry out
calibration of the barometric sensor
for lack of measuring equipment, it is
possible to set the instrument in
manual configuration to correct the
atmospheric pressure. As a result,
when starting the test, the
instrument will display a screen for
entering the barometric pressure
using the keyboard.
Display mode allows displaying the current calibration points and reading the atmospheric
pressure in real time.
When entering the calibration points, the instrument waits for stabilisation of the
measurement (variation below 0.3 mB) and calculates and average of five consecutive
acquisitions.
In order to perform a calibration which is sufficiently accurate, the two calibration points
must be a minimum of 100 mB apart.

gauge used as the reference
T-junction connecting the sensor of the
instrument under calibration and the
absolute standard reference pressure
gauge to the pump.
