SETUP AND INSTALL
Mount the Analyzer
The Model 3000TA is for indoor use in a general purpose area. It is NOT for hazardous
environments of any type. It is designed for flush panel mounting. Use the four mounting holes—
one in each corner of the rigid frame to panel mount the instrument.
Gas Connections
Note: Do not remove plastic caps on VCR fittings, unless you are ready to make
connections.
The analyzer is equipped with 1/4 inch tube fittings, and 6 mm adapters are supplied for
metric system installations.
You will need:
• Zero gas — regulated supply of oxygen free gas.
• Span gas — regulated supply of a standard gas typically containing oxygen at 70-
90% of the full scale value on the range of interest.
• Purge gas — oxygen free inert gas for purging if applicable.
• Sample gas — regulated supply of sample gas available to the analyzer.
Make your gas connections to the analyzer as follows:
1. Install the flow restrictor that shipped with your instrument:
• For positive pressure applications, install the restrictor with the blue dot to the
SAMPLE IN port. The small circular orifice should face away from the back of
the unit. Remove the sticker after installing.
• For low pressure applications (less than 5 psig), connect the restrictor without the
blue dot to the SAMPLE IN port.
• For vacuum service (5-10 in Hg), install the restrictor without the blue dot to the
EXHAUST port.
2. Connect your sample gas to the SAMPLE IN port.
3. Connect a vent line to EXHAUST OUT port.
