M703E Calibrator Operator’s Manual Safety Messages
SAFETY MESSAGES
Your safety and the safety of others are 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 M703E
Photometric O3 Calibrator. The definition of these symbols is described below:
GENERAL SAFETY HAZARD: Refer to the instructions for details on the specific
hazard.
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 M703E Photometric O3 Calibrator should only be used for the purpose and in the manner described
in this manual. If you use the M703E in a manner other than that for which it was intended,
unpredictable behavior could ensue with possible hazardous consequences.
NOTE
Technical Assistance regarding the use and maintenance of the
M703E or any other Teledyne Instruments product
can be obtained by:

M703E Calibrator Operator’s Manual Introduction
1. INTRODUCTION
1.1. M703E CALIBRATOR OVERVIEW
The Model 703E is a microprocessor-based ozone calibrator for calibration of ambient ozone analyzers, such as
the T-API M400E. The M703E features an internal ozone photometer that provides very accurate closed loop
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
Optional Ethernet connectivity
12 independent timers for sequences
Nested sequences (up to 5 levels)
Internal ozone generator and photometer allows use as primary or transfer standard

1. Inspect the received packages for external shipping damage. If damaged, please advise the shipper
first, then Teledyne Instruments.
2. Included with your calibrator is a printed record of the final performance characterization performed on
your instrument at the factory. This record, titled Final Test and Validation Data Sheet
important quality assurance and calibration record for this instrument. It should be placed in the quality
records file for this instrument.
3. Carefully remove the top cover of the calibrator and check for internal shipping damage.
Remove the set-screw located in the top, center of the Front panel.

(P/N 05760) is an
Remove the 2 screws fastening the top cover to the unit (one per side towards the rear).
Slide the cover backwards until it clears the calibrator’s front bezel.
Lift the cover straight up.
NOTE
Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small to be felt by the
human nervous system. Failure to use ESD protection when working with electronic assemblies will
void the instrument warranty.
See Chapter 12 for more information on preventing ESD damage.
CAUTION
NEVER DISCONNECT ELECTRONIC CIRCUIT BOARDS, WIRING HARNESSES OR
4. Inspect the interior of the instrument to make sure all circuit boards and other components are in good
shape and properly seated.
5. Check the connectors of the various internal wiring harnesses and pneumatic hoses to make sure they
are firmly and properly seated.

3.2. ELECTRICAL CONNECTIONS
3.2.1. POWER CONNECTION
Verify the correct line voltage and frequency configuration on the serial number tag on the rear panel of the
M703E.
Attach the power cord to the calibrator and plug it into a power outlet capable of carrying at least 10 A current at
your AC voltage and that it is equipped with a functioning earth ground.
CAUTION
HIGH VOLTAGES ARE PRESENT INSIDE THE CALIBRATORS CASE
POWER CONNECTION MUST HAVE FUNCTIONING GROUND CONNECTION.
DO NOT DEFEAT THE GROUND WIRE ON POWER PLUG.
TURN OFF CALIBRATOR POWER BEFORE DISCONNECTING OR
CONNECTING ELECTRICAL SUBASSEMBLIES.
CAUTION
DO NOT LOOK AT THE PHOTOMETER UV LAMP.
UV LIGHT CAN CAUSE EYE DAMAGE.
ALWAYS WEAR GLASSES MADE FROM SAFETY UV FILTERING GLASS
(PLASTIC GLASSES WILL NOT DO).
3.2.2. ANALOG OUTPUT TEST CHANNEL CONNECTIONS
The M703E is equipped with an analog output channel accessible through a connector on the back panel of the
instrument. The standard configuration for this output is 0-5 VDC. It can be set by the user to output one of a
variety of diagnostic test functions (see Section 6.9.)
To acce
connections on the rear panel of the calibrator.
ss these
signals attach a strip chart recorder and/or data-logger to the appropriate analog output
Pin-outs for the analog output connector at the rear panel of the instrument are:

Getting Started M703E Calibrator Operator’s Manual
3.2.3. CONNECTING THE STATUS OUTPUTS
The status outputs report calibrator conditions via optically isolated NPN transistors, which sink up to 50 mA of
DC current. These outputs can be used interface with devices that accept logic-level digital inputs, such as
programmable logic controllers (PLC’s). Each Status bit is an open collector output that can withstand up to 40
VDC. All of the emitters of these transistors are tied together and available at D.
NOTE
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
function of each pin is defined in Table 3-1.
