Teledyne API Model 100A SO2Analyzer Instruction Manual, 02164, Rev. G
1 HOW TO USE THIS MANUAL
The Model 100A has been designed with serviceability, reliability and ease of operation in mind.
The M100A's microprocessor continually checks operating parameters such as temperature,
flow, and critical voltages. The instruments modular design uses captive screws to facilitate
repair and ease of access. If you encounter any difficulty refer to Section 9 General
Troubleshooting Hints.
We recognize that the need for information in this manual changes as time passes. When the
instrument first arrives, it is necessary to get it up and running quickly and verify its correct
operation. As time passes, more detailed information is often required on special configurations,
calibration alternatives and other operational details. Finally there is the need for periodic
maintenance and to quickly troubleshoot problems to assure maximum uptime and data integrity.
To address these needs, we have created three indexes to the information inside. They are:
Table of Contents:
Outlines the contents of the manual in the order the information is presented. This is a good
overview of the topics covered in the manual. There is also a list of Tables and a list of Figures.
Index to M100A Front Panel Menus:
The Menu Index (Figure 5-1 and Figure 5-2, and Table 5-2) briefly describes the front panel
menus and refers you to other sections of the manual that have a detailed explanation of each
menu selection.
Troubleshooting Section 9
The Troubleshooting Section, outlined in the Table of contents, allows you to diagnose and repair
the instrument based on variables in the TEST menu, the results of DIAGNOSTIC tests, and
performance faults such as excessive noise or drift. The troubleshooting section also explains the
operation, adjustment, diagnosis and testing of each instrument subsystem.
If you are unpacking the instrument for the first time, please refer to Getting Started in
Section 2.

1.1 Safety Messages
Your safety and the safety of others is very important. We have provided many important safety
messages in this manual. Please read these messages carefully.
A safety message alerts you to potential hazards that could hurt you or others. Each safety
message is associated with a safety alert symbol. These symbols are found in the manual and
inside the instrument. The definition of these symbols is described below:
GENERAL WARNING/CAUTION: Refer to the instructions for details on the
specific danger.
CAUTION: Hot Surface Warning
CAUTION: Electrical Shock Hazard
Technician Symbol: All operations marked with this symbol are to be performed
by qualified maintenance personnel only.
CAUTION
The analyzer should only be used for the purpose
and in the manner described in this manual.
If you use the analyzer in a manner other than that for which
it was intended, unpredictable behavior could ensue with
possibly hazardous consequences.

2 GETTING STARTED
2.1 Installation
CAUTION
To avoid personal injury, always use two persons to
lift and carry the Model 100A.
8. Verify that there is no apparent shipping damage. If damage has occurred please advise shipper
first, then Teledyne API.
1. Before operation it is necessary to remove the shipping hold-down screws. Remove the
instrument cover, then refer to Figure 2-1 for screw location.
Note:
Save the shipping screws and re-install them whenever the unit is shipped to another location.
2. While the instrument cover is removed, please check the voltage and frequency label on
the cover of the power supply module and compare that to your local power before plugging
in the M100A.
9. Check for internal shipping damage, and generally inspect the interior of the instrument to make
sure all circuit boards and other components are in good shape.
3. Replace the instrument cover.
4. When installing the M100A, allow at least 4” (10 cm) clearance at the back and at least
1” (2.5 cm) clearance at each side for proper venting.
2.2 Electrical and Pneumatic Connections
10. Refer to Figure 2-2 to locate the rear panel electrical and pneumatic connections.
11. The pressure of the sample gas at the inlet port should be at atmospheric pressure (Refer to Figure
2-3 and Figure 7-1 for pneumatic system connection).
1. Connect the analyzer exhaust to a suitable vent at atmospheric pressure. (See Figure 2-3
for exhaust line venting recommendations.)
2-1

Teledyne API Model 100A SO2Analyzer Instruction Manual, 02164, Rev. G
2. If desired, attach the analog output connections to a strip chart recorder and/or
datalogger. Refer to Figure 9-3 for jumper settings for the desired analog output voltage
range. Factory default setting is 0-5VDC.
3. Connect the power cord to the correct voltage line, then turn to Section 2.3 Initial
Operation.
CAUTION
High voltages present inside case.
DO NOT LOOK AT THE UV LAMP, UV LIGHT
COULD CASE EYE DAMAGE.
ALWAYS USE SAFETY GLASSES
(PLASTIC GLASSES WILL NOT DO).
Connect the exhaust fitting on the rear panel to a
suitable vent outside of the room.
CAUTION
DO NOT OPERATE WITH COVER OFF.
Before operation check for correct line voltage and
frequency on Serial Number Sticker.
Do not plug in the power cord if the voltage or
frequency is incorrect.
Do not operate without proper chassis grounding.
Do not defeat the ground wire on power plug.
Turn off analyzer power before disconnecting or
connecting eletrical subassemblies.
Always replace shipping screws when transporting the Analyzer.

2.3 Initial Operation
12. Turn on the instrument power.
1. The display should immediately light, displaying the instrument type (M100A) and the
CPU memory configuration. If you are unfamiliar with the M100A, we recommend that you
read the overview Section 4 before proceeding. A diagram of the software menu trees is in
Figure 5-1 and Figure 5-2.
13. The M100A requires about 60 minutes for all internal components to come up to temperature.
2. While waiting for instrument temperatures to come up, you can check for correct
operation by using some of the M100A's diagnostic and test features.
3. Examine the TEST functions by comparing the values listed in Table 2-1 to those in the
display. Remember that as the instrument warms up the values may change until they reach
their final values. If you would like to know more about the meaning and utility of each
TEST function refer to Table 9-1. Table 2-1 also contains the list of options. Section 6 covers
setting up the options.
4. When the instrument is warmed up, re-check the TEST functions against Table 2-1. All
of the readings should compare closely with those in the Table. If they do not, see Section
9.1.1.
NOTE
Do not calibrate the analyzer within 60 minutes after the power reset.
2-6

Teledyne API Model 100A SO2Analyzer Instruction Manual, 02164, Rev. G
The next task is to calibrate the analyzer. There are several ways to do a calibration; they are
summarized in Table 7-1. For a preliminary checkout we recommend calibration with zero air and
span gas coming in through the sample port. The procedure is:
Step 1 - Enter the expected SO2span gas concentration
Step Number Action Comment
1. Press CAL-CONC This key sequence causes the M100A to prompt for the
expected SO2concentration. Enter the SO2span concentration
value by pressing the key under each digit until the expected
value is set.
2. Press ENTR ENTR stores the expected SO2span value. This value will be
used in the internal formulas to compute subsequent SO2
concentration values.
3. Press EXIT Returns instrument to SAMPLE mode.
4. Press SETUP-
RNGE-SET
If necessary you may want to change ranges. Normally the
instrument is shipped with range set at 500 ppb.
5. Press EXIT Returns the instrument to SAMPLE mode.
2-7

Teledyne API Model 100A SO2Analyzer Instruction Manual, 02164, Rev. G
Step 2 - Calibrate the instrument:
Zero/Span Calibration Procedure
Step Number Action Comment
1. Input Zero gas Allow Zero gas to enter the sample port on the rear of the
instrument.
2. Press CAL The M100A enters the calibrate mode from sample mode.
3. Wait 10 min Wait for reading to stabilize at the zero value. (If you wait less
than 10 minutes the final zero value may drift.)
4. Press ZERO The ZERO button will be displayed.
5. Press ENTR Pressing ENTR actually changes the calculation equations and
zeroes the instrument.
6. Press EXIT M100A returns to the CAL menu. Now switch gas streams to
span gas.
7. Wait 10 min Wait for reading to stabilize at the span value. (If you wait less
than 10 minutes the final span value may drift.)
8. Press SPAN The SPAN button should be displayed. If it is not, check the
Troubleshooting Section 9.2.8 for instructions on how to
proceed. In certain circumstances at low span gas
concentrations (<100ppb), both the ZERO and SPAN buttons
will appear.
9. Press ENTR Pressing ENTR actually changes the calculation equations so
that the concentration displayed is the same as the expected
span concentration you entered above, thus spanning the
