3.1. UNPACKING AND INITIAL SETUP
CAUTION
To avoid personal injury, always use two persons to lift and carry the Model T101.
CAUTION – Avoid Warranty Invalidation
Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small
to be felt by the human nervous system. Damage resulting from failure to use ESD
protection when working with electronic assemblies will void the instrument warranty.
See A Primer on Electro-Static Discharge in this manual for more information on preventing
ESD damage.
Remove dust plugs prior to operating instrument. It is recommended that you store shipping
containers/materials, including shipping screws and dust plugs for the pneumatic ports, for future use
if/when the instrument should be returned to the factory for repair and/or calibration service. See
Warranty section in this manual and shipping procedures on our Website at
http://www.teledyne-api.com under Customer Support > Return Authorization.
1. Inspect the received packages for external shipping damage. If damaged,
please advise the shipper first, then Teledyne API.
2. Included with your analyzer is a printed record (Form number 04551) of
the final performance characterization performed on your instrument at

1. Attach the 1/4" exhaust line to the EXHAUST port of the analyzer and to
the inlet port of the pump.
42
Page 45
Teledyne API – T101 Operation Manual Getting Started
07266B DCN6485
CAUTION
The exhaust from the external pump needs to be vented outside the immediate area or
shelter surrounding the instrument and conform to all safety requirements using a
maximum of 10 meters of 1/4” PTFE tubing.
2. Attach the sample line to the SAMPLE inlet port. Ideally, the pressure of
the sample gas should be equal to ambient atmospheric pressure.
NOTE
Maximum pressure of any gas at the sample inlet should not exceed 0.5 in-Hg above ambient pressure
and ideally should equal ambient atmospheric pressure.
In applications where the sample gas is received from a pressurized manifold, a vent must be provided to
equalize the sample gas with ambient atmospheric pressure before it enters the analy zer. The v ented gas
needs to be routed outside the immediate area or shelter surrounding the instrument.
3. Attach zero air and span gas supply lines as appropriate (see Figures 3-6
& 3.7). For this type of analyzer, zero air and span gas are defined as
follows:
Zero air and span gas inlets should supply their respective gases in excess
of the 700 cc
3
/min demand of the analyzer. Supply and vent lines should
be of sufficient length and diameter to prevent back diffusion and pressure
effects.
SPAN GAS
Span gas is specifically mixed to match the chemical composition of the type of gas being
measured at near full scale of the desired measurement range. In the case of H
measurements made with the Model T101 UV Fluorescence H
recommended that you use a span gas with a H
concentration equal to 90% of the
2S

specifications (also referred to as SRM’s or EPA protocol calibration gases) are
commercially available. Table 3-5 lists specific NIST-SRM reference numbers for various
concentrations of H

2
Some applications, such as EPA monitoring, require a multipoint calibration procedure
where span gases of different concentrations are needed. We recommend using a bottle of
calibrated H
S gas of higher concentration in conjunction with a gas dilution calibrator such
2
as a Teledyne API Model T700. This type of calibrator precisely mixes a high
concentration gas from zero air (both supplied externally) to accurately produce span gas
of the correct concentration. Linearity profiles can be automated with this model and run
unattended over night.

S. If your analyzer is equipped with an
2
IZS or external zero air scrubber option, it is capable of creating zero air.
For analyzers without these options, a zero air generator such as the Teledyne API Model
701 can be used.
Once the appropriate pneumatic connections have been made, check all pneumatic fittings
for leaks using a procedure similar to that defined in Section 9.5.1.

Both supply lines should be vented outside of the analyzer’s enclosure. In order to prevent
back-diffusion and pressure effects, these vent lines should be between 2 and 10 meters in
length.
INTERNAL ZERO/SPAN (IZS) VALVE GAS FLOW
The T101 can be equipped with an internal zero air and span gas generator (IZS). This
option includes a heated enclosure for a permeation tube for containing the calibration gas
under high pressure (not included; H
perm tubes must be ordered from a manufacturer), an external scrubber for producing

zero air and a set of valves for switching between the sample gas inlet and the output of
the zero/span subsystem, functionally very similar to the valves included in the zero/span
valve option.

/min.
NOTE
The instrument can only be fitted with one type of permeation tube at a time. Therefore the IZS option can
only be used to calibrate or check the instrument for one gas, H2S or SO2, but not both.
External Zero Air Scrubber
The IZS option includes an external zero air scrubber assembly that removes all H2S the
zero air source. The scrubber is filled with activated charcoal.
The Permeation Source
Span gas is created when zero air passes over a permeation tube containing liquid H2S
under high pressure, which slowly permeates through a PTFE membrane into the
surrounding air. The speed at which the H
S permeates the membrane is called the
2
effusion rate. The concentration of the span gas is determined by three factors: membrane
size, sample gas temperature, and zero air flow rate
Size of the membrane: The larger the area of the membrane, the more permeation
occurs.
47
Page 50
Getting Started Teledyne API – T101 Operation Manual
07266B DCN6485
Temperature of the H2S: Increasing the temperature of the increases the pressure inside
the tube and therefore increases the effusion rate.
Flow rate of the zero air: If the previous two variables are constant, the permeation rate
of the calibration gas into the zero air stream will be constant. Therefore, a lower flow
rate of zero air produces higher concentrations of H
S. The T101 usually has a constant
2
flow rate and a constant permeation rate; hence, variations in concentration can be
achieved by changing the IZS temperature.
NOTE
The permeation tube is not included in the IZS Option and must be ordered separately.
Permeation Tube Heater
In order to keep the permeation rate constant, the IZS enclosure is heated to a constant
50° C (10° above the maximum operating temperature of the instrument). The IZS heater
is controlled by a precise PID (Proportional/Integral/Derivative) temperature control loop.
A thermistor measures the actual temperature and reports it to the CPU for control
feedback.

3.6.2. INTERFERENCES FOR H2S MEASUREMENTS
It should be noted that the fluorescence method for detecting H2S is subject to
interference from a number of sources. Since the T101 converts H
measures the UV fluorescence of the SO
from other gases that fluoresce in a similar fashion to SO
, the most common source of interference is
2
, when exposed to UV Light
2
such poly-nuclear aromatics (PNA), of which certain hydrocarbons such as meta-xylene
and naphthalene are the most pervasive. The T101 has been successfully tested for its
ability to reject interference from most of these sources.
For a more detailed discussion of this topic, see Section 10.2.6.

4. OPERATING INSTRUCTIONS
The T101 is a micro-computer-controlled analyzer with a dynamic menu interface for
easy and yet powerful and flexible operation. All major operations are controlled from
the front panel touch screen control.
To assist in navigating the system’s software, a series of menu trees can be found in
Appendix A of this manual.
NOTE
The ENTR button may disappear if you select a setting that is invalid or out of the allowable range for that
parameter, such as trying to set the 24-hour clock to 25:00:00. Once you adjust the setting to a n
allowable value, the ENTR button will reappear.
4.1. OVERVIEW OF OPERATING MODES
The T101 software has a variety of operating modes. Most commonly, the analyzer will
be operating in SAMPLE mode. In this mode, a continuous read-out of the H
concentration is displayed on the front panel and output as an analog voltage from rear
panel terminals, calibrations can be performed, and TEST functions and WARNING
messages can be examined.
The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, such as for the DAS system, the reporting
ranges, or the serial (RS-232/RS-485/Ethernet) communication channels. The SET UP
mode is also used for performing various diagnostic tests during troubleshooting.
The Mode field of the front panel display indicates to the user which operating mode the
unit is currently running.
In addition to SAMPLE and SETUP, other modes the analyzer can be operated in are:

If the instrument includes either the zero/span valve option or IZS option, the display will
also include CALZ and CALS buttons. Pressing either of these buttons also puts the
instrument into multipoint calibration mode.
The CALZ button is used to initiate a calibration of the zero point.
The CALS button is used to calibrate the span point of the analyzer. It is
recommended that this span calibration is performed at 90% of full scale
of the analyzer’s currently selected reporting range.
Because of their critical importance and complexity, calibration operations are described
in Section 6 of this manual.
4.3.1. CALIBRATION PASSWORD SECURITY

All three outputs can be configured either at the factory or by the user for full scale
outputs of 0.1 VDC, 1VDC, 5VDC or 10VDC. Additionally A1 and A2 may be equipped
with optional 0-20 mADC current loop drivers and configured for any current output
within that range (e.g. 0-20, 2-20, 4-20, etc.). The user may also adjust the signal level
and scaling of the actual output voltage or current to match the input requirements of the
recorder or data logger (See Sections 4.6.3.3 and 4.6.3.5).

4.4.4.2. Physical Range versus Analog Output Reporting Ranges
The T101 UV Fluorescence H2S Analyzer has two hardware physical ranges that cover
H
S concentrations between 0 and 20,000 ppb. The low range is 0 to 2,000 ppb, while the
2
high range is 0 to 20,000 ppb. The proper physical range is determined by the software to
include the maximum measurement concentration selected by the user. Once properly
calibrated, the analyzer’s front panel will accurately report concentrations along the entire
span of its 0 and 20,000 ppb physical range.
Because, most applications use only a small part of the analyzer’s two physical ranges,
the width of the Model T101’s physical range can create data resolution problems for
most analog recording devices. For example, in an application where the expected
concentration of SO
only 0.25% of the instrument’s 20,000 ppb physical range. Unmodified, the
corresponding output signal would also be recorded across only 0.25% of the range of the
recording device.
The T101 solves this problem by allowing the user to select a scaled reporting range for
the analog outputs that only includes that portion of the physical range relevant to the
specific application. Only the reporting range of the analog outputs is scaled, the physical
range of the analyzer and the readings displayed on the front panel remain unaltered.

The default range mode for the analyzer is single range, in which all analog concentration
outputs are set to the same reporting range. This reporting range can be set to any value
between 5.0 ppb and 20 000 ppb.
While the two outputs always have the same reporting range, the span and scaling of their
electronic signals may also be configured for different differently (e.g., A1 = 0-10 V; A2

4.4.4.5. Independent Range Mode (IND)
Selecting independent range mode allows the A1 and A2 outputs to be configured with
different measurement ranges. The analyzer software calls these two ranges LOW and
HIGH. The LOW range setting corresponds with the analog output labeled A1 on the
rear panel of the instrument. The HIGH range setting corresponds with the A2 output.
While the software names these two ranges LOW and HIGH, they do not have to be
configured that way.

4.4.4.8. Dilution Ratio
The dilution ratio is a software option that allows the user to compensate for any dilution
of the sample gas before it enters the sample inlet.
1. Select reporting range units: Follow the procedure in Section 4.4.4.7.
2. Select the range: Use the procedures in Section 4.4.4.3 – 4.4.4.6.
Make su
that the SPAN value entered is the maximum expected concentration of
the undiluted calibration gas, and
that the span gas is either supplied through the same dilution inlet system
as the sample gas or has an appropriately lower actual concentration.
For example, with a dilution set to 100, a 1 ppm gas can be used to
calibrate a 100 ppm sample gas if the span gas is not routed through the
dilution system. On the other hand, if a 100 ppm span gas is used, it
needs to pass through the same dilution steps as the sample gas.
3. Set the dilution factor as a gain (e.g., a value of 20 means 20 parts
diluent and 1 part of sample gas):

4.4.5. SETUP – PASS: PASSWORD PROTECTION
The menu system provides password protection of the calibration and setup functions to
prevent unauthorized adjustments. When the passwords have been enabled in the PASS
menu item, the system will prompt the user for a password anytime a password-protected
function (e.g., SETUP) is selected. This allows normal operation of the instrument, but
requires the password (101) to access to the menus under SETUP. When PASSWORD is
disabled (SETUP>OFF), any operator can enter the Primary Setup (SETUP) and
Secondary Setup (SETUP>MORE) menus. Whether PASSWORD is enabled or disabled,
a password (default 818) is required to enter the VARS or DIAG menus in the

4.5. SETUP – VARS: USING THE INTERNAL VARIABLES
The T101 has several-user adjustable software variables, which define certain operational
parameters. Usually, these variables are automatically set by the instrument’s firmware,
but can be manually re-defined using the VARS menu. Table Table 4-7 lists variables that
are available within the 818 password protected level.

4.5.1. SETTING THE GAS MEASUREMENT MODE
If the switching valves software is activated, the T101 can be set to one of three gas
measurement modes:
H2S
The sample gas stream is stripped of any ambient SO
chemical scrubber, then passed through a catalytic converter that changes
the H
S present into SO2 which is then measured using the UV
2
Fluorescence method
SO
2
The sample gas stream bypasses the SO2 Scrubber and catalytic converter
allowing the only ambient SO
H

to be measured.

The switching valve alternates the gas stream between the two paths at
regular intervals allowing the instrument to measure both gases.

4.6. SETUP – DIAG: USING THE DIAGNOSTICS
FUNCTIONS
A series of diagnostic tools is grouped together under the SETUPMOREDIAG
menu. As these parameters are dependent on firmware revision (see Menu Tree A-5 in
Appendix A). The individual parameters, however, are explained in more detail in the
following section, indicated in Table 4-8. These tools can be used in a variety of
troubleshooti
maintenance and trouble-shooting sections.
Table 4-8. T101 Diagnostic (DIAG) Functions
DIAGNOSTIC FUNCTION AND MEANING
SIGNAL I/O: Allows observation of all digital and analog signals in the
instrument. Allows certain digital signals such as valves and heaters to be
toggled ON and OFF.
ANALOG OUTPUT: When entered, the analyzer performs an analog
output step test. This can be used to calibrate a chart recorder or to test
the analog output accuracy.
ANALOG I/O CONFIGURATION: Analog input/output parameters are
available for viewing and configuration.
OPTIC TEST When activated, the analyzer performs an optic test, which
turns on an LED located inside the sensor module near the PMT (Fig. 10-
15). This diagnostic tests the response of the PMT without having to
supply span gas.
ELECTRICAL TEST: When activated, the analyzer performs an electric
test, which generates a current intended to simulate the PMT output to
verify the signal handling and conditioning of the PMT preamp board.
LAMP CALIBRATION: The analyzer records the current voltage output
of the UV source reference detector. This value is used by the CPU to
calculate the lamp ration used in determining the H
(see 10.2.2)
PRESSURE CALIBRATION: The analyzer records the current output of
the sample gas pressure sensor. This value is used by the CPU to
compensate the H
FLOW CALIBRATION: This function is used to calibrate the gas flow
output signals of sample gas and ozone supply. These settings are
retained when exiting DIAG.
TEST CHAN OUTPUT: Configures the A4 analog output channel. DIAG TCHN 4.6.9

been installed) and the signal level that matches the input requirements of the
recording device attached to the channel (Section 4.6.3.1).
Calib
rating the output channel. This can be done automatically or manually for each
channel (Sections 4.6.3.2 and 4.6.3.3).
Adding a bip

4.6.3.2. Analog Output Calibration Mode
Analog output calibration should be carried out on first startup of the analyzer (performed
in the factory as part of the configuration process) or whenever recalibration is required.
The analog outputs can be calibrated automatically, either as a group or individually, or
adjusted manually.
In its default mode, the instrument is configured for automatic calibration of all channels,
which is useful for clearing any analog calibration warnings associated with channels that
will not be used or connected to any input or recording device, e.g., datalogger.
Manual calibration should be used for the 0.1V range or in cases where the outputs must
be closely matched to the characteristics of the recording device. Manual calibration
requires the AUTOCAL feature to be disabled.
To calibrate the outputs as a group, activate the ANALOG I/O configuration menu (see
Section 4.6.3), then press:

4.6.3.4. Analog Output Offset Adjust ment
Some analog signal recorders require that the zero signal is significantly different from
the baseline of the recorder in order to record slightly negative readings from noise
around the zero point. This can be achieved in the T101 by defining a zero offset, a small
voltage (e.g., 10% of span), which can be added to the signal of individual output
channels by activating the ANALOG I/O CONFIGURATION MENU (see Section 4.6.3),

4.6.3.5. Current Loop Output Adjustment
92
A current loop option is available and can be installed as a retrofit for each of the analog
outputs of the analyzer. This option converts the DC voltage analog output to a current
signal with 0-20 mA output current. The outputs can be scaled to any set of limits within
that 0-20 mA range. However, most current loop applications call for either 2-20 mA or
4-20 mA range. All current loop outputs have a +5% over-range. Ranges with the lower
limit set to more than 1 mA (e.g., 2-20 or 4-20 mA) also have a -5% under-range.
To switch an analog output from voltage to current loop after installing the current output
printed circuit assembly, follow the instructions in Section 4.6.3.1 and select curr from the
list of opti
on the “Output Range” menu.
ons
Adjusting the signal zero and span values of the current loop output is done by raising or
lowering the voltage of the respective analog output. This proportionally raises or lowers
the current produced by the current loop option.

Similar to the voltage calibration, the software allows this current adjustment to be made
in 100, 10 or 1 count increments. Since the exact current increment per voltage count
varies from output to output and from instrument to instrument, you will need to measure
the change in the current with a current meter placed in series with the output circuit
(Figure 4-5).

If a current meter is not available, an alternative method for calibrating the current loop

4.6.4. OPTIC TEST
The optic test function tests the response of the PMT sensor by turning on an LED located
in the cooling block of the PMT (Fig. 10-15). The analyzer uses the light emitted from the
LED to test its photo-electronic subsystem, including the PMT and the current to voltage
converter on the pre-amplifier board. To make sure that the analyzer measures only the
light coming from the LED, the analyzer should be supplied with zero air. The optic test
should produce a PMT signal of about 2000±1000 mV. To activate the electrical test

4.6.5. ELECTRICAL TEST
The electrical test function creates a current, which substitutes the PMT signal, and feeds
it into the preamplifier board. This signal is generated by circuitry on the pre-amplifier
board itself and tests the filtering and amplification functions of that assembly along with
the A/D converter on the motherboard. It does not test the PMT itself. The electrical test
should produce a PMT signal of about 2000 ±1000 mV.
