BGA244 Binary Gas Analyzer
Installation and Configuration
Plan your installation, including mounting and gas tubing connections. Depending on
your application, this can be as simple as setting the BGA244 on a bench and connecting
flexible tubing or may involve hard mounting the unit and forming metal tubing. Be sure
to clean out gas lines prior to connecting them to the BGA244 to avoid contamination.
Refer to Chapter 2 (Installation Guide) of the User Manual if you have any questions
regarding these procedures as improper installation can damage the unit.
1.
Mount the BGA244 as appropriate to your application.
2.
Connect the gas tubing to the gas ports following the appropriate procedure for
the specific gas fittings. Either gas port can be used for input or output.
3.
Connect either USB power or +24 V
DC
. If using USB power, be certain that the
USB device and cable are sufficient to power the device. Refer to Power
(Chapter 2 of the User Manual) for more information. The splash screen and
“About” page should appear as described in Quick Test.
4.
Configure the BGA244. Note that it may be easier to configure the unit prior to
installing it into your system, especially if access is restricted. See Chapter 3
(Operation Guide) of the User Manual
for more information on each of the
following steps.
a.
Set the Instrument Mode:
There are 3 choices: Binary Gas Analyzer, Gas Purity Analyzer or Physical
Measurements.
b.
Select the Gases: [HOME] [SETUP] [SELECT GAS]. Set the Primary Gas
and Secondary Gas (note that a Secondary Gas is not required for the
Gas Purity Mode). Press [SELECT GAS] to open the gas selection window.
Type the first few characters of its name, formula or CAS number, then
press [ENTER] to open a list of gases that match that string. Select the
desired gas from that list.
c.
Configure the Pressure: [HOME] [SETUP] [PRESSURE]. There are two
ways to enter pressure information to the BGA244. See Pressure
(Chapter 3 in the User Manual) for information. You can use the
following procedure assuming you are operating at a known, static
pressure.
Press [ENTER USER PRESSURE] to open the User pressure window. Enter
the pressure and select gauge or absolute units. Enter the ambient
pressure if using gauge units.
d.
Set the Meter Scale and Limits: [HOME] [METER SCALE] and
[HOME] [LIMITS] appropriately. (For the Binary Gas and Gas Purity
Analyzers only).
5.
Flow gas through the system. The BGA244 should display the selected gases and
concentration, purity or physical measurements of the gas.
