
Pressure fields :

P1 field: pressure value upstream the critical orifice,

P2 field: pressure value downstream the critical orifice,

Atm. field: atmospheric pressure.

Temperature fields :

Filter field : temperature at filter level,

Atm. field: external temperature measured by the meteo sensor (if the meteo sensor option is
available).

Flow-rate fields: flow-rate parameters for the current measurement.
Automatic calculation of the flow rate coefficient :

Procedure: it consists in inputting the flow rate values given by the reference flow meter
connected to the analyzer, then to validate this value with the [

] key. The instrument
automatically modifies the flow rate F coefficient, and displays the new flow rate value measured
by the analyzer, which is obtained with the new coefficient.

Operating mode :

Using the [

] key, go to « Calibration » line, then press down the [

] key to activate the input
field of the flow rate value read on the reference flow meter connected to the instrument.

Using the [

], [

] and [

] keys, input the flow rate value, stated in l/min, read on the flow
meter. Validate the input with the F6 [

] key.

Then, the instrument calculates the flow rate span coefficient. : and « F Coef. » is displayed in
the corresponding field.
Validate the calculated coefficient by pressing down the [Memo] key

the new F Coef. is
memorized, its value is updated, and the flow rate measurement is adjusted to the reference
value.
