1. PREFACE
Note The information contained in this addendum is pertinent to T100U
analyzers running software revision Gc4. Some or all of the information
may not be applicable to later revisions of software. The software
revision that your analyzer is running is displayed in the Mode field of the
display any time the analyzer is in SETUP mode.
This addendum is based on the Model T100 Operators Manual (P/N 06807). In most
ways the T100U is identical to the T100 in design and operation; therefore, most of the
basic set up information, operating instructions as well as calibration, maintenance,
troubleshooting and repair methods are found in that manual. This addendum
documents only those areas where the T100U is different in design or operating method
from the T100.
Therefore, this addendum includes instructions and information regarding:
•Additional Test Functions
•Adjusting the PMT HV for “Factory Calibrations”
•Differences in theory of operation
1.1 REFERENCE NUMBERING CONVENTION
Unless otherwise specified, section, figure and table reference numbers referred to
within this text are relative to this manual.
EXAMPLE: “Figure 2-1” refers to the figure within this document labeled as
Figure 2-1.
References to sections, figures and tables in the T100 manual will be labeled as such.
EXAMPLE: “Figure 6-1 of the T100 Operators Manual” (P/N 06807).

2.2 EPA EQUIVALENCY DESIGNATION
Teledyne API’s T100U trace level sulfur dioxide analyzer is designated as a reference
method for SO2measurement, as defined in 40 CFR Part 53, when operated under the
conditions defined for the T100 analyzer (manual PN 06807).
2.3 CE MARK COMPLIANCE
The T100U analyzer emissions and safety compliance are the same as those for the T100
analyzer.

3. GETTING STARTED
3.1 UNPACKING THE T100U
Unpack the T100U as per the directions in Section 3.1 of the T100 Manual, with the
following change: There are two redheaded shipping screws that hold down the
PMT/Sensor assembly and must be removed prior to operation. They are located along
the base of the PMT housing adjacent to the chassis.
3.2 INTERNAL LAYOUTS
Figures 3-1 replaces Figure 3-5 in the T100 manual. The primary difference between
the T100U and T100 layouts is the differences in the PMT Housing, the location of the
PMT preamp PCA and the addition of a Sync Demodulator PCA.

Lamp calibration was performed.
STR. LGT Stray Light ppb The offset due to stray light recorded by the CPU during the last

DRK PMT Dark PMT mV The PMT output reading recorded as the lamp pulses off during
normal measurement.

pulses off during normal measurement.

calibration activity.The slope parameter is used to set the span
calibration point of the analyzer.

4. T100U OPERATING INSTRUCTIONS
Note For the most part the operation instructions for the T100U are the same
as those described in the T100 Manual with the exception that there are
additional test parameters and setup procedures.
4.1 ADDITIONAL TEST PARAMETERS
Please see Section 3.3 of this addendum for details on the additional test parameters.
4.2 STBL MENU: SETUP FOR THE THREE STABILITY
FUNCTIONS
There is an additional submenu on the Secondary Setup Menu in the T100U’s software.
The STBL menu, see Figure 4-1 allows the user to modify the settings for the three
stability calculations that are displayed as Test Functions on the front panel and are
available via the serial data port and that can be logged with the DAS. Test Function
STABIL, CONC1 in the menus below, is equivalent to the standard T100 STABIL
function and is useful when conducting calibrations and other operations in which the
operator has limited time to view the display. CONC2, which is the same as the
STABIL2 test function has been configured so that it calculates stability in the same way
as required by the EPA. STABIL2 is useful when comparing instruments against the
EPA standard but is very slow and difficult to use for calibration or other activities
where the operator must wait for analyzer to settle to the desired value. UVLAMP is
the same as UV STAB on the front panel is a diagnostic that can be used to understand
the stability of the UV lamp.

5. CALIBRATION PROCEDURES
Calibration of the T100U should be performed according to the procedures described in
the T100 Manual. However, delivering span and zero gases for the lower ranges that the
T100U is designed for can be difficult. For best results when calibrating the T100U, wait
one hour for the instrument to stabilize when delivering zero and span gases before
pressing the zero and span buttons. Attention must be paid to the quality of the gasses,
the level of contaminants in the gases as well as the history and conditioning of the gas
delivery components. Only Teflon or glass should be used for any “wetted” surfaces
that the calibration gasses contact. All delivery system components should be
conditioned by running span gas for a minimum of four hours before conducting actual
span calibrations.
