TPS Aqua-D Manuale utente
Congratulations !
You have purchased the latest in Handheld, Waterproof Dissolved
Oxygen - Temperature instrumentation. This manual is for both the
Aqua-D, which uses the TPS ED1 sensor, and for the Aqua-DY, which
uses the YSI Dissolved Oxygen sensor. For simplicity, we refer only to
“Aqua-D” throughout the manual.
The Aqua-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 Aqua-D. It also contains a full listing of all of the items
that you should have received with your Aqua-D. 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
Aqua-D, 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.

¬Display
24 character alpha-numeric display. Can show any of the following
combinations of readouts (see section 2).
% Saturation +
Temperature Salinity-corrected ppM
(mg/L) + Temperature
Salinity Correction
Value (in ppK) Temperature only
A unique “Large Digit” mode nearly doubles the size of the digits
(section 2).
User-friendly prompts and error messages are also provided.
-Used to calibrate all parameters. See sections 3, 4and 5.
®Used to select % Saturation, ppM, Manual Salinity or Temperature
modes. See section 2.
¯Switches the Aqua-D on and off.
Hold this key for 3 seconds to invoke Battery Saver mode. See
section 6.
°and ±
These keys toggle the Aqua-D between Large Display mode and
Dual Display mode. See section 2.
NOTE: The digits in Large Display mode are made by combining the
two rows of the display. This results in a small gap
approximately half way up the digits.

2. Operating Modes
Press the key to select the desired operating mode. The sequence is
shown in the following table…
% Saturation Mode 100.0%S
25.0oc
Dissolved Oxygen data in % Saturation units is shown on the top line and
Temperature data is shown on the bottom line.
Select this mode to calibrate the % Saturation readout.
Press or to toggle between dual readout or large digit readout.
↓↓
ppM Mode 8.24ppMS
25.0oc
Dissolved Oxygen data in ppM (mg/L) units is shown on the top line and
Temperature data is shown on the bottom line.
Select this mode to calibrate the ppM readout.
The “S” is shown after the “ppM” units when the Salinity correction value is
set to greater than 0.0ppK (see section 5).
Press or to toggle between dual readout or large digit readout.
↓↓
Salinity Mode 36.0ppK
The Salinity correction value only is shown on the top line.
Select this mode to set the Salinity correction value.

Operating modes, continued…
Temperature Mode 25.0oc
Temperature data only is shown on the top line.
Select this mode to calibrate Temperature.
Press or to toggle between regular readout or large digit readout.

Back to % Saturation mode
Note: The decimal point is replaced by a ” ∗∗ “ if a Dissolved Oxygen or
Temperature calibration has failed (see sections 3and 4), if the unit is
initialised (see section 7), or if the unit has lost its factory calibration (see
section 9.1).
