Teledyne API T703/T703U Calibrator Operation Manual Introduction

07223C DCN6572

1. INTRODUCTION

This manual provides information and operation instructions for the Model T703 and the Model T703U calibrators. For simplicity the information and instructions in this manual refer to both models except where the Model T703U diverges in technical or operational aspects, in which case the T703U is clearly defined.

1.1. T703/T703U CALIBRATOR OVERVIEW

The Model T703 and the T703U are microprocessor controlled ozone calibrators for calibration of precision ambient ozone instruments, such as the TAPI T400. They feature an internal ozone photometer that provides very accurate closed loop feedback control of the ozone concentration. However, the T703U is capable of generating ozone in a low range (fractional mode), for ultra-low ozone production.

As many as 50 independent calibration sequences may be programmed into the T703/T703U, 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 T703/T703U 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 instruments.

Some of the exceptional features of your T703/T703U Photometric O

 Advanced T-Series electronics  LCD Graphical User Interface with capacitive touch screen  Bi directional RS-232 and 10/100Base-T Ethernet, optional USB and RS-485, ports

for remote operation

 Front panel USB ports for peripheral devices  12 independent timers for sequences  Nested sequences (up to 5 levels)  Internal ozone generator and photometer allows use as primary or transfer standard  UV Lamp Feedback modes: current control; reference detector control; photometer

control

 Lightweight for transportability  T703U: ultra-low ozone production down to 3ppb

Calibrator are:

3. GETTING STARTED

3.1. UNPACKING AND INITIAL SETUP

CAUTION

THE T703 WEIGHS ABOUT 16.1 KG (35.5 POUNDS) WITHOUT OPTIONS

INSTALLED. TO AVOID PERSONAL INJURY, WE RECOMMEND USING TWO

PERSONS TO LIFT AND CARRY THE CALIBRATOR.

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.

CAUTION – Avoid Damage to the Instrument

Do not operate the instrument without first removing dust plugs from pneumatic ports.

NOTE

It is recommended that you store shipping containers/materials 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.

WARNING!

NEVER DISCONNECT ELECTRONIC CIRCUIT BOARDS, WIRING HARNESSES

OR ELECTRONIC SUBASSEMBLIES WHILE THE UNIT IS UNDER POWER.

1. Inspect the received packages for external shipping damage. If damaged, please advise the shipper first, then Teledyne API.

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 (P/N 05760) is an 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.

Getting Started Teledyne API T703/T703U Calibrator Operation Manual

07223C DCN6572

 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.

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.

6. Verify that all of the optional hardware ordered with the unit has been installed. These are checked on the paperwork accompanying the calibrator.

VENTILATION CLEARANCE: Whether the calibrator is set up on a bench or

installed into an instrument rack, be sure to leave sufficient ventilation clearance.

AREA MINIMUM REQUIRED CLEARANCE

Back of the instrument 10 cm / 4 inches

Sides of the instrument 2.5 cm / 1 inch

Above and below the instrument. 2.5 cm / 1 inch

3.1.1. FRONT, REAR, AND INTERNAL CALIBRATOR DESCRIPTION

Figure 3-1 shows the location of the front panel components. Figure 3-2 shows the display screen, which is described in Table 3-1.

Figure 3-2: Display Screen and Touch Control

The front panel liquid crystal display (LCD) screen includes touch control. Upon calibrator start-up, the LCD shows a splash screen and other initialization indicators before the main display appears.

CAUTION – Avoid Damaging Touchscreen

Do not use hard-surfaced instruments such as pens to operate the touch screen buttons.

Table 3-1: Display Screen and Touch Control Description

Field Description/Function

LEDs indicating the states of the calibrator:

Name Color State Definition

Unit is operating in STANDBY mode.

Active Green off

Target/ Actual Gas concentrations, Cal gas MFC and Diluent MFC values with unit of measure

Mode Displays the name of the calibrator’s current operating mode (default is STANDBY at initial startup).

Param

Touchscreen control: row of eight buttons with dynamic, context sensitive labels; buttons are blank when inactive/inapplicable.

Auto Timer Yellow off

Fault Red blinking

Displays a variety of informational messages such as warning messages, operational data, test function values and response messages during interactive tasks.

This LED is lit when the instrument is actively producing calibration gas (GENERATE mode).

This LED is lit only when the calibrator is performing an automatic calibration sequence.

The calibrator is warming up and therefore many of its subsystems are not yet operating within their optimum ranges. Various warning messages may appear in the Param field.

Figure 3-3 shows how the front panel display is mapped to the menu charts that are illustrated throughout this manual.
