3.4.2.1
molbloc-L Operation
The molbox1+ gases available for use with molbloc-L at the time of this manual
printing are listed in Table 19.
<1inert>
<2flammable>
<1N2> Nitrogen
<1H2>
<2He> Helium
<2O2>
<3Ar> Argon
<3CH4>
<4C2H4> Ethylene
<5C3H8> Propane
<6C2H6> Ethane
<7Butn> Butane
•
<Butn> is used to identify Butane in molbox1+ because the
chemical symbol for Butane (C4H10) has more than the 4
characters
identifications.
•
Mixtures of known gases in known concentrations can be
measured by calculation and use of the ADJ function (see
Section 3.5.3).
OPERATION (molbloc-L Operation)
To specify the gas flowing through molbloc-L,
press [GAS]. The display is:
The gases available are grouped in categories
to facilitate finding a specific gas and as a
reminder to the user when selecting a gas that
may require special precautions in use. There
is a list of gases under each category. For
example, the <1inert> selection displays:
A secondary menu displays when a specifically
calibrated gas is selected. The menu includes:
the name of the gas, calibration name, the
calibrated flow range, the calibration type
(PREM for premium or STD for standard) and
the supported pressure range.
calibrations are available for the selected gas
arrow keys "<>" display after the pressure. Use
the left right arrow keys to select the other
calibrations.
If the selected gas is not specifically calibrated
on the molbloc a secondary menu displays
indicating that the default calibration for the
molbloc will be used to derive the flow of the
selected gas. Press enter to proceed.
Select the desired gas. Pressing [ENTER] returns to the last run screen with
the selected gas active. The selected gas is always displayed in the upper right
hand corner of the MAIN run screen.
