quaprobe® Lite Instruction Manual 10401-00976 Rev F
1. Introduction
This manual covers the setup, operation, calibration and maintenance of the Aquaprobe®
AP-Lite V4.00+, Aquameter® V6.00+ Meter, AquaLink V4.00+ PC software and associated
Aquaprobe® accessories. If your Aquaprobe® or Aquameter® are running earlier software,
the functionality may differ from that shown in this manual. In this case, contact Aquaread
for an earlier version of this manual or return your equipment for software upgrade.
2. What’s in the Box?
The AP-Lite is supplied with the following:
Sleeve End Cap.
One mounting nut (pre-fitted).
Getting started card for quick reference.
Pot of Silicone Grease
To complete your system, you will need an Aquameter® (AM- 00) an Optical Electrode of
your choice and an Aquaprobe® Extension Cable, which should be purchased separately.
2.1. About the Aquameter®
The Aquameter® is designed to be used outdoors and is rated to IP67, that is to say it is
waterproof but it is not designed for submersion. In order to prevent accidental dunking or
loss, a lanyard is supplied.
Please note that the socket on the Aquameter® is only waterproof when the
associated plug is fitted. Without the plug fitted, water can enter the socket. Damage
caused by water ingress through the socket is not covered by your warranty.
You may notice a small hole on the rear of the unit near the top. This is a waterproof vent
for the internal barometric sensor. Do not poke anything in this hole! Doing so will cause
major damage to the vent’s waterproof membrane and invalidate your warranty.
The lanyard supplied with the Aquameter® may, at first, appear to be a little long. This is
intentional. In order to keep the Meter out of the way whilst your hands are full, the lanyard
has been made long enough to wear round your neck and over your shoulder so the Meter
sits on your hip.
The extra length also allows the meter to be held in a comfortable position in front of you
during normal use. In order to prevent you being dragged into the water in the event of the
Probe cable becoming snagged, the lanyard includes a quick-release clip.
2.2. AP-Lite Minimum and Maximum Insertion Levels
The AP-Lite is designed to be fully submerged in water and is rated to IP68, that is to say, it
is rated for continual immersion to a depth of 30 meters, and short term immersion to 100
meters.
Temperature is measured in the AP-Lite by a sensor located in the blue socket block. The
recommended minimum level of insertion is therefore the blue line half way up the Probe.
The Probe will operate with just the lower row of holes in the Sleeve covered, but the
temperature measurement response will be slower as the temperature of the liquid being
measures will take a short time to conduct to the socket block via the Probe's Sleeve.

quaprobe® Lite Instruction Manual 10401-00976 Rev F
2.3. About the Probe Sleeve and nd Cap
Please refer to the diagram and photograph below when reading the following important
information.
All Aquaread® Optical Electrodes are incredibly sensitive. For example, the Turbidity
electrode is capable of measuring between 0 and 3000NTU with an internal resolution of
greater than 0.1NTU. This means that the electrode is able to detect changes in turbidity
that are less than 0.003% of the full range! The other optical electrodes have a similar level
of sensitivity.
It follows, therefore, that in order to provide stable, repeatable readings, the environment in
which the measurements are made must be completely stable and repeatable.
The AP-Lite is constructed with a
matt black aluminium sleeve and
end cap that enclose the sensing
electrode and provide a closed,
constant condition, non reflective
measurement chamber.
This is essential for the correct
calibration and operation of all types
of optical electrodes.
In order to obtain consistent
results, the measurement
chamber created within the AP-
Lite must remain physically
constant during both calibration
and measurement.
Both the Sleeve and Sleeve nd
Cap must be fitted during
calibration and measurement
including when using the AP-Lite
with the optional Flow Through
Cell (Flowcell).
If the optical electrode is calibrated under one set of conditions then used to measure under
another set of conditions, the readings will naturally be erroneous, especially at low
concentrations.
A perfect example of this is calibrating with the end cap removed then measuring with the
end cap fitted (or vice-versa). By changing the physical characteristics of the measurement
chamber, you also change the calibration and response of the electrode.
© 2015 quaread® Ltd. www.aquaread.com Page 7 of 72

quaprobe® Lite Instruction Manual 10401-00976 Rev F
Another particular problem when trying to measure very low
concentrations is air in the form of both visible and
microscopic bubbles. These act like tiny prisms and can
refract and reflect both the excitation light and the return
signal being measured.
The photograph to the right was taken in a calibration tube
after fresh water was poured in. The bubbles are clearly
visible in the light beam.
2.4. Top Tips for successful measurements using optical electrodes
Always keep the measurement chamber and electrode lenses clean.
Always fit the sleeve and end cap during both calibration and measurement.
Always allow the readings to settle completely during both calibration and
measurement.
Always try to eliminate air bubbles by agitating the Probe after insertion both during
calibration and measurement. On the AP-7000, activate the self-cleaning mechanism to
clear bubbles.
Always calibrate and zero the electrode as close to your sample temperature as
possible. This is especially important with the Ref-Oil electrode.
Always zero the electrode just prior to use in clean water (bottled still mineral water is
ideal). This is also especially important with the Ref-Oil electrode.
2.5. About Fluorescent Measurement
All Optical Electrodes, with the exception of the Turbidity Electrode, employ fluorescent
measurement techniques. Interference from microbiological species and compounds which
fluoresce at similar wavelengths and differences in fluorescence caused by temperature,
ambient light and turbidity can all cause inaccuracies.
Fluorescence measurement is ideal for researchers who are interested in detecting the
presence or absence of a specific substance in reasonable concentrations and measuring
relative fluorescence changes that can be used as an indication of increasing or decreasing
concentrations.
Fluorescence measurement techniques are not ideal for quantitative measurement and it is
therefore impossible to specify an absolute accuracy.
In order to obtain accurate results, data obtained with a fluorescent electrode in the
field must be post-calibrated with data from standard laboratory analysis of grab
samples acquired during the study.

3. Battery Installation and Care
The Aquameter® requires five AA size batteries. To install the batteries, loosen the two
screws on the centreline of the rear of the meter and remove the battery compartment lid.
Following the battery polarity markings inside the battery compartment, insert five AA cells
then replace the compartment lid and tighten the screws.
3.1. Choice of Battery Type
Alkaline or rechargeable batteries may be used, but never mix battery types in the meter. If
you choose to use rechargeable batteries, we recommend nergizer 500mAh (or greater)
Nickel-Metal Hydride cells, which are widely available.
If the Meter is to be out of use for a long period, remove the batteries to prevent damage
due to possible leakage.
3.2. Battery Life
A set of fresh alkaline cells will give over 0 hours use in the AM- 00 GPS Aquameter®. A
fully charged set of 500mAh NiMH cells will give up to 40 hours use in the AM- 00 GPS
Aquameter®.
3.3. Battery Charging
During the charging process, batteries generate heat and vent gasses, and must never be
charged inside a sealed unit. Because the Aquameter® is a sealed unit, we do not allow
charging in-situ. Batteries must be removed and charged with a suitable battery charger
outside the Meter. We recommend the use of one of the nergizer range of NiMH chargers.
3.4. Battery Condition Icon
On the main Aquameter® screens, a battery condition icon is displayed in the top left
corner. The icon shows full when the batteries are fresh, and gradually empties as the
batteries are used. When the batteries need replacing, the empty battery icon will flash on
and off. If you ignore this, the Meter will automatically switch itself off when the battery
voltage becomes too low for reliable operation.
When using rechargeable batteries, the battery icon will not show completely full, even with
freshly charged cells. This is due to the fact that rechargeable batteries are only rated at
1. V per cell compared to 1.5V per cell for alkaline batteries. This indication does not affect
battery life. The icon will simply sit at the ¾ full mark for a longer period of time.
3.5. Battery Saver Functions
The Aquameter® is designed to switch off automatically if you do not touch any of the keys
for 30 minutes. The only exception to this is if you have activated the Automatic Data
Logging feature. In this case, the Meter will continue to operate until either the memory is
full or the batteries go flat.
The display on the Aquameter® incorporates a white backlight to improve visibility in low-
light conditions. As on a mobile phone, the backlight switches on each time a key is
pressed, and stays on at full brightness for 15 seconds. After 15 seconds, the backlight will
fade to half brightness. After a further 15 seconds the backlight will switch off.
During normal operation, if you want to activate the backlight without changing the Meter
function, simply press the SC or OK key.

4. Overview of the Operating System
The operating software in the Aquameter® has been designed for simple, intuitive use.
Similarly, a great deal of development work has been put into simplifying and automating
the calibration procedures in the Aquameter® in order to allow normal field operatives (as
opposed to trained lab technicians) to achieve quick and accurate results.
If you are used to operating a mobile phone or programming audio/visual equipment using
a remote control, you should feel at home with the familiar up/down left/right arrow shaped
navigation keys and central OK key.
The tree structure behind the M NU key should also be very familiar. Each item on the
menu leads to a sub menu and then either onto further menus or final choices. Each
branch of the menu system is navigated using the arrow keys. At each point, selections can
be made by either pressing the OK key or the right arrow key.
To reverse along a branch of the menu system, use the SC (escape) key or left arrow
key. After a short time, you should be able to navigate around the entire menu system at
speed using just the four arrow keys. If, at any time, you leave the Meter in one of the sub-
menu screens, it will automatically back out to the main operating screen after 15 seconds.
4.1. Initial Switch On, Language and Clock Setup
To switch the meter on or off, briefly press the red key. Do not hold it down. The meter
contains a clock and is capable of operating in several different languages. When switching
on for the first time, you must select an operating language and set the clock. The first
screen you will see is the Language Selection Screen.
 English
Francais
Deutsch
Espanol
To select a language, move the cursor down the list using the down arrow key. To enter
your selection, press the OK key or the right arrow key.
The next screen to be displayed is the Time & Date Setting Screen.
Time & Date
 Time:15:46:37
Date:15/Jun/12
To set the time and date, use the arrow keys to move the cursor around the screen. Use
the up and down arrow keys to adjust values. When the time and date are correct, press
the OK key. Don’t worry if you make a mistake first time round. You can easily get back to
these screens later through the M NU key.
