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 7090% 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.
Teledyne Analytical Instruments

Model 3000TA
Quickstart Guide
4. If using remote calibration feature:
•
Connect zero gas to the ZERO IN port.
•
Connect span gas to the SPAN IN port.
5. Otherwise, calibration gases must be Tee'd into the sample inlet with appropriate
valves.
6. Regulate the sample gas pressure between 2 and 50 psig sufficient to keep the front
panel flowmeter reading in an acceptable range (0.1 to 2.4 SLPM). For nonpressurized sample or very low pressure, (less than 2 psig) vacuum service plumbing
is recommended.
7. If greater sample flow is required for improved response time, install a bypass in the
sampling system upstream of the analyzer input.
8. For optional vacuum application where the sample pressure is at atmospheric or very
low pressure, the instrument should be fitted with the vacuum service option. This
option locates the flow control valve on the exhaust side of the Micro-fuel Cell.
Note: Exhaust connections must be consistent with the hazard level of the constituent
gases. Check Local, State, and Federal laws, and ensure that the exhaust
stream vents to an appropriately controlled area, if required.

Password Protection
If a password is assigned, then setting the following system parameters can be done only
after the password is entered: span and zero settings, alarm setpoints, analysis range definitions,
switching between autoranging and manual override, setting up an auto-cal, and assigning a new
password. However, the instrument can still be used for analysis or for initiating a self-test
without entering the password.
If you have decided not to employ password security, use the default password TETAI. This
password will be displayed automatically by the microprocessor. The operator just presses the
Enter key to be allowed total access to the instrument’s features.
Note: If you use password security, it is advisable to keep a copy of the password in a
separate, safe location.
Entering the Password
To install a new password or change a previously installed password, you must key in and
Enter the old password first. If the default password is in effect, pressing the Enter button will
enter the default TETAI password for you.

Calibration of the Analyzer
The analyzer is calibrated using zero and span gases. This Quickstart Guide describes both
manual and auto mode calibration. You can s switch between the two any time using the
procedures described below.
Any suitable oxygen-free gas can be used for zero gas as long as it is known to be oxygen
free and does not react adversely with the sample system. For span gas, use a known gas
containing oxygen in the range of 70-90% of full scale on the range of interest.
Zero Calibration
Make sure an appropriate zero gas is connected to the sample port. Adjust the gas pressure
until the flowrate as indicated on the front panel flowmeter settles between 0.1 and 2.4 SLPM
(0.2 –5 SCFH).
