Photometric Analyzer Part II: Analysis Unit
Part II: 2-3 Teledyne Analytical Instruments
2.2.7 Draining the System
In liquid analysis systems, the system drain manifold must terminate in a
safe area as the sample may be poisonous or corrosive.
2.3 Testing the System
Before plugging the instrument into the power source:
• Check the integrity and accuracy of the fluid connections. Make
sure there are no leaks.
• Check the integrity and accuracy of the electrical connections.
Make sure there are no exposed conductors
• Check that sample pressure is between 3 and 40 psig, according
to the requirements of your process.
NOTE: Special designed systems may require checks under vacuum
or high pressure (consult manual addendum).
Power up the system, and test it by performing the following
operations:
1. Repeat the Self-Diagnostic Test, section 3.3.4, part I
2.4 Calibration
2.4.1 Calibration Fluids
Zero and span fluids must be made by the chemistry lab or certified zero
and span gas bought from a gas supplier. The zero fluid must be the major
component of the sample, free from the component of interest.
The span fluid must be the major component of the sample mixed with
a small amount of the component of interest. The concentration must be 80 to
95% of the range or the widest range of the instrument (if the instrument provides
more than one range).
2.4.2 Calibration
Refer to Section 3.3.8 section I of the manual to determine how to
manipulate the mode setting. Two calibration methods are available.
1. Calibration with zero and span fluids.
