feedback control of the ozone concentration.
As many as 50 independent calibration sequences may be programmed into the M703E, covering time periods
of up to one year. The setup of sequences is simple and intuitive. These sequences may be actuated manually,
automatically, or by a remote signal. The sequences may be uploaded remotely, including remote editing. All
programs are maintained in non-volatile memory.
The M703E design emphasizes fast response, repeatability, overall accuracy and ease of operation. It may be
combined with the Model 701 Zero Air Generator to provide the ultimate in easy to use, precise calibration for
your ozone analyzers.
Some of the exceptional features of your M703E Photometric O3 Calibrator are:
Advanced E Series electronics
Lightweight for transportability

Most PLC’s have internal provisions for limiting the current that the input will draw from an external
device. When connecting to a unit that does not have this feature, an external dropping resistor must be
used to limit the current through the transistor output to less than 50 mA. At 50 mA, the transistor will
drop approximately 1.2V from its collector to emitter.
The status outputs are accessed via a 12-pin connector on the calibrator’s rear panel labeled STATUS. The

3.3. PNENUMATIC CONNECTIONS
Figure 3-9: Basic Pneumatic Setup of M703E
3.3.1. DRY AIR IN
When using the internal zero air pump, a source of dry air should be connected to the port labeled ‘Dry Air In’ on
the rear panel. This air should be supplied at atmospheric pressure. The supplied air should have a dew point
of –20 C or less.
Teledyne API can supply an optional desiccant cartridge that can be used to supply dry air to the M703E.
3.3.2. ZERO AIR IN
An external pressurized source of zero air can be supplied at the ‘Zero Air” port on the rear panel. This is the
standard configuration when the zero air pump is not installed. This zero air should be scrubbed of ozone and
have a dew point of -20 C or less. The pressure of the zero air should be regulated to 20-35 psig.
NOTE
When connecting an external source of zero air to an M703E with an internal zero air pump installed, the
zero air pump should be disabled.
The “ZA_PUMP_ENABLE” VAR (see Section 6.10) should be set to OFF.

3.3.3. OUTPUT MANIFOLD
A four-port output manifold is supplied on the rear panel of the M703E enabling simultaneous testing of up to two
external analyzers. Sample lines for ozone analyzers to be calibrated can be connected directly to this manifold.
To prevent ozone exposure, the bottom port of this manifold is used as a vent and should be connected to a
proper unpressurized vent manifold. It is important that the backpressure at this vent fitting be kept to a
minimum. If a vent line longer than 2 meters (~6 feet) is required, then 3/8” OD tubing should be used.
Any unused ports on this manifold must be capped.
3.3.4. EXHAUST
The port labeled ‘EXHAUST’ contains the exhaust gas from the internal photometer and may contain ozone.
This port should be connected to a proper unpressurized vent manifold to prevent ozone exposure.
3.3.5. MEASURING AN EXTERNAL OZONE SOURCE
The M703E can easily be configured to measure an external source of ozone.
See Section 6.11 for details on operating the M703E in this manner.

3.4.4. FUNCTIONAL CHECK
7. After the calibrator’s components have warmed up for at least 30 minutes, verify that the software
properly supports any hardware options that are installed.
8. Check to make sure that the calibrator is functioning within allowable operating parameters. Appendix C
includes a list of test functions viewable from the calibrator’s front panel as well as their expected values.
These functions are also useful tools for diagnosing problems with your calibrator (see Section7.5.2).
The enclosed Final Test and Validation Data sheet (part number 05760) lists these values before the
instrument left the factory.
To view the current values of these parameters press the following key sequence on the calibrator’s front

9. If your calibrator has an Ethernet card (Option 63) installed and your network is running a dynamic host
configuration protocol (DHCP) software package, the Ethernet option will automatically configure its
interface with your LAN. However, it is a good idea to check these settings to make sure that the DHCP
has successfully downloaded the appropriate network settings from your network server (See Section
7.5.2).
If your network is not running DHCP, you will have to configure the calibrator’s interface manually (See
Section 7.5.2.

3.4.5. OPERATING MODES FOR THE O3 GENERATOR
The O3 generator can be set to operate in three different modes:
3.4.5.1. CNST (CONSTANT)
In this mode, the O3 output of the generator is based on a single, constant, drive voltage. There is no Feedback
loop control by the M703E’s CPU in this mode.
3.4.5.2. REF (REFERENCE)
The O3 control loop will use the reference detector’s measurement of the O3 generator’s UV lamp as input. This
mode does not use the photometer to control the ozone generator.
3.4.5.3. BNCH (BENCH)
The O3 concentration control loop will use the photometer’s O3 measurement as input.
THIS IS THE DEFAULT AND MOST COMMON MODE OF OPERATION.
This setting will be the default mode of the M703E calibrator and will be mused whenever the calibrator is using
the GENERATE AUTO command or the GENERATE sequence step to create a calibration mixture. When
either the GENERATE MAN command or the MANUAL sequence step is active, the local O
(chosen during when the command/step is programmed) will take precedence.

3.4.7. SETTING THE M703E’S OUTPUT FLOW RATE
The output flow rate of the M703E should be adjusted to match the gas flow requirements of the analyzers
connected to the output manifold.
NOTE
The minimum total flow should equal the sum of the flow requirements of all of the instruments to
which the M703E will be supplying calibration gas plus 1 LPM excess flow.
Example: If the M703E is will be expected to supply calibration gas mixtures simultaneously to two
analyzers each requiring 0.8 LPM , the proper Total Flow output should be set at a minimum of:
(0.8 + 0.8) + 1.0= 2.6 LPM
To set the output flow:
1. Open the front panel of the calibrator down by releasing the two snap-in fasteners at the top of the front
panel.
2. Pull out the regulator knob and adjust the regulator until the desired flow is achieved.
The front panel of the M703E displays the approximate output flow based on the measured regulator
pressure, but this flow should be verified with an independent calibrated flow meter attached to the
on of the CAL GAS outlets on the back of the instrument (see Figure 3-2).
3. Push the reg
ulator knob back in to lock.
4. Close the front panel.

6. OPERATING THE M703E CALIBRATOR
The M703E calibrator is a computer-controlled calibrator with a dynamic menu interface for easy and yet
powerful and flexible operation. All major operations are controlled from the front panel display and keyboard
through these user-friendly menus.
To assist in navigating the system’s software, a series of menu trees can be found in Appendix A of this manual.
NOTE
The flowcharts in this chapter depict the manner in which the front panel display/keyboard interface is
used to operate the M703E Photometric Calibrator.
They depict typical representations of the display during the various operations being described.
They are not intended to be exact and may differ slightly from the actual display of your system.
NOTE
When editing values in the software, the ENTR key may disappear if you select a value that is invalid or
out of the allowable range for that parameter (e.g. such as trying to set the 24-hour clock to 25:00:00).
Once you adjust the setting to an allowable value, the ENTR key will re-appear.

6.2. OVERVIEW OF OPERATING MODES
The M703E calibrator software has a variety of operating modes. Most commonly, the calibrator will be
operating in STANDBY mode. In this mode, the calibrator and all of its subsystems are inactive although TEST
functions and WARNING messages are still updated can be examined via the front panel.
The second most important operating mode is SETUP mode. This mode is used for performing certain
configuration operations, such as programming the concentration of source gases, setting up automatic
calibration sequences and configuring the analog / digital inputs and outputs. The SET UP mode is also used
for accessing various diagnostic tests and functions during troubleshooting.

6.5. AUTOMATIC CALIBRATION SEQUENCES
The M703E calibrator can be set up to perform automatic calibration sequences of multiple steps. These
sequences can perform all of the calibration operations available for manual operation and can be set up to be
triggered by using the front panel buttons, the M703E’s internal timer, the external digital control inputs, the RS232 interface, via the optional Ethernet interface or even as sub-processes in another sequence.
6.5.1. SETUP SEQ: PROGRAMMING CALIBRATION
SEQUENCES
A sequence is a database of single or multiple steps where each single step is an instruction that causes the
instrument to perform an operation. These steps are grouped under a user defined SEQUENCE
For each sequence, seven attributes must be programmed. They are:

Some analog signal recorders require that the zero signal be 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

6.9.2. TEST CHANNEL CALIBRATION
TEST CHANNEL calibration needs to be carried out on first startup of the analyzer (performed in the factory as
part of the configuration process) or whenever re-calibration is required. The analog outputs can be calibrated
automatically or adjusted manually.
During automatic calibration, the analyzer tells the output circuitry to generate a zero mV signal and high-scale
point signal (usually about 90% of chosen analog signal scale) then measures actual signal of the output. Any
error at zero or high-scale is corrected with a slope and offset.
Automatic calibration can be performed via the
located inside
CHANNEL
TEST_CHANNEL submenu. By default, the analyzer is configured so that calibration of TEST
can be initiated with the AOUTS CALIBRATION command.

with data loggers located central data analysis facility is possible to collect and buffer data between the various
calibrators, analyzers and metrological equipment remotely located at an air monitoring station.
Because LEADS was originally developed for use with TNRCC using Dasibi 5008 calibrators, the LEADS
version of the M703E includes support for Dasibi “Dot” serial data commands and operational “LEVEL’s”.
NOTE
For more information on the LEADS system, please go to http://www.meteostar.com/.
6.12.2. DOT COMMANDS
The Dasibi “Dot” commands form a text-based (ASCII) data protocol that is transmitted between a control
computer (XENO data logger in this case) and a calibrator or ambient gas analyzer over an RS-232 connection.
The details of the protocol are beyond the scope of this document, but in its simplest form the protocol is based
on a two or three digit integer preceded by a control-A and a period (.) and then followed by a “!” and a two digit
checksum.
EXAMPLE:
^A.xxx!nn
For further information on dot commands, please contact T-API customer service.
An M703E equipped with LEADS software can be simultaneously operated over the same COM port using
standard Teledyne Instruments’ serial data commands and is compatible with APIcom versions 3.7.3 and later
which include an added feature that allows a user to edit, upload and download level tables.

6.12.3. LEVELS
A LEVEL is a combination of several parameters:
An ID number for the LEVEL
An action, (e.g. GENERATE, STANDBY)
A target concentration value
An output flow rate (if applicable)
Configuration for one or both of two status output blocks.
Up to twenty levels can be defined and used with the M703E using a range of ID numbers from 0-98. Level 99
is reserved for standby. Are not time based and do not include characteristics such as start time or duration,
therefore a single LEVEL can not switch between different concentration levels and flow rates. Separate flow
and concentration outputs must be programmed into separate LEVELs which are then individually started and
stopped either by an operator at the calibrator’s front panel or through a serial data operation over the RS-232 or
Ethernet ports.
