It must also configure the reference program with the master parameters.
¾ Calibration pressure.
¾ Master flow.
¾ Atmospheric pressure of the calibration.
¾ Calibration temperature.
¾ Drift.
The drift is calculated between the first and the last master jet measurement (reference
cycle realization). If it's higher than the programmed level, a error message appears.
Only a manual acquit can be possible ("Drift acquit" special cycle).
) Select the option and adjust settings if necessary.
2.1.3. 4) Automatic mode
This function launches the test cycle automatically, it therefore avoids the need for a
pressing of the cycle start by the operator. The cycling of this test is on is own part.
The automatic function allows launching a test cycle as the part to be tested to the
measurement circuit connection. The start cycle is made when the test pressure is
between the minimum and the maximum levels.
In the case of use of the personalized measurements units (CAL) it's
imperative to make a learning cycle before starting a test cycle. The learning error
can generate an instrument blocking mode.
) Select the option and adjust settings if necessary.
2.1.3. 5) Units
This function allows the operator to choose the units system required: SI, international
metric unit system, USA, Anglo-Saxon international units system (inches, feet) and
CAL, the operator personalized unit system (this system requires the carrying out of a
learning cycle.
) Select the option and adjust settings if necessary.
2.1.3. 6) Filtering
This function ensures the slowing or the acceleration the sampling speed, by carrying
out an average over the measurement time set, making the reading of the measurement
more user friendly.
) Select the option and adjust settings if necessary.
2.1.3. 7) Standard conditions
The "Standard conditions" function allows the returning of the results measured by the
instrument to defined atmospheric conditions.
The measurements depend on the ambient temperature and atmospheric pressure.
When the function is activated, the instrument recalculates the flow results according to
the atmospheric conditions inputted. Therefore the results of the measurements will not
take into account the ambient variations.
To confirm this function, an asterisk is displayed after "FLOW".
) Select the option and adjust settings if necessary.
