TPS smartCHEM-D User manual

Congratulations !
The smartCHEM-Dis an advanced, high quality Dissolved Oxygen, Conductivity, TDS and
Temperature meter.
Despite its impressive list of features, the smartCHEM-D 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-D. 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-D, including
operating modes, calibration, troubleshooting, specifications, and warranty terms.

1. Introduction
1.1 smartCHEM-D Display and Controls
1.2 smartCHEM-D Rear Panel Connectors
Turn the retaining nut clockwise until it clicks into place when plugging in plastic
connectors. This is essential to produce a waterproof seal.
Always replace the waterproof cap when a connector is not in use to maintain
waterproof integrity.

1.4 One-touch Keys
:Press to manually record readings into the Logger. See section 11.1.
:Press to transmit current reading plus date and time to the RS232 port. See section 12.2.
:Press to start and stop Automatic Datalogging. See section 11.2.
: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. Shows Dissolved Oxygen, Conductivity/TDS, Temperature, Date and Time
simultaneously.
Backlight can be set to On, Off or Energy Saver modes. See section 8.
