TPS smartCHEM-Titro User manual

Congratulations !
The smartCHEM-Titro is an advanced, high quality pH, mV & Temperature instrument. It
features the ability to directly connect to a Schott Universal burette for Automatic Titration
applications.
Despite its impressive list of features, the smartCHEM-Titro is a breeze to operate. This manual
has been designed to help you get started, and also contains some handy application tips. If at any
stage you require assistance, please contact either your local TPS representative or the TPS factory
in Brisbane.
The manual is divided into the following sections:
1. Table of Contents
Each major section of the handbook is clearly listed. Sub-sections have also been included to
enable you to find the information you need at a glance.
2. Introduction
The introduction has a diagram and explanation of the display and controls of the
smartCHEM-Titro. It also contains a full listing of all of the items that you should have
received with the unit. Please take the time to read this section, as it explains some of items that
are mentioned in subsequent sections.
3. Main Section
The main section of the handbook provides complete details of the smartCHEM-Titro,
including operating modes, calibration, troubleshooting, specifications, and warranty terms.
4. Appendices
Appendices containing background information and application notes are provided at the back
of this manual.

menu one level at a time, and as an “escape” key to quit functions such as calibration, data entry etc.
Press the to function keys to select desired options within the menu system.
Additionally, these keys perform the following function directly in normal measurement mode…
: Press to start the Automatic Titration (section 3.4).
: Press to start and stop the Automatic Stability Function. See section 8.
1.4 One-Touch Keys
: Press to manually record readings into the Logger. See section 12.1.
: Press to transmit current reading plus date and time to the RS232 port. See section 13.2.
: Press to start and stop Automatic Datalogging. See section 12.2.
: Press to accept default values or those entered on the Numeric Keypad.
1.5 Numeric Keypad
Used to enter values during set-up and calibration. A decimal point is provided.
1.6 Delete Key
Press to make corrections to values entered on the Numeric Keypad.
1.7 240 x 64 Dot Graphic Display
Graphic display with large, clear digits and letters. Features a user-friendly menu and context-
sensitive help system. pH/mV/Relative mV, Temperature, Dosed mL and Time simultaneously.
