2. General
AQUA-CHECK 2 is a highly sensitive photometer for the precise
determination of substance concentrations in water and is used in the
following areas:
- Aquariums and ponds
- Fish breeding and aqua cultures
- Swimming pools
Reference reagents for photometric measurements are required for
this, and can be bought in retail outlets.
Please always wear safety glasses (normal glasses are not safety
glasses, as they are open at the side) when using the respective
reagents.
Read these operating instructions carefully before you use.
Please observe the usual safety precautions when handling
chemicals. Use of the photometer with reagents (chemicals) is not
permitted for people under 16 years. Please also ensure that the
photometer is not accessible for children under 3 years, as it contains
small parts that could be swallowed.
The measurement device is spray water protected.
Only immerse the measurement component (measuring tube) into
the water. Do not immerse the device (apart for the measuring tube)
into or under water.

2.1 Proper intended use
The AQUA-CHECK 2 Photometer is ONLY used for determining
8 parameters, which are present in aqueous solutions and in the
temperature range from +5°C to +40°C.
Aqueous solutions are all types of water, such as those in aqua
cultures, fresh and sea water aquariums, pond systems and
swimming pools. Wrong uses could, for example, include:
Non-aqueous mixtures and ammable liquids, use as a tool, temperatures that are too high >40°C.
2.2 Product monitoring
Please inform us if any faults or problems occur when using
the Photometer, in particular if they result in any kind of accident.

3. Operating
3.1 Battery
After you have removed the battery from the
protective sleeve included, insert it into the battery slot.
Open the cover on the rear side of the housing with a coin.
Place the battery with the +- pole up (showing to the
opening) into the slot and press it into the battery
holder with a rod or suchlike (no metal), until it clicks in.
Then screw the cover back on. You must ensure here that
the rubber ring on the opening lies completely in the slot.
Any possible water penetration that could destroy the electronics
can then be prevented. Then turn the device around and conrm
with the "OK" button.
The following appears in the display:
You have inserted the battery properly. If the display does not
show any message, the battery has been inserted incorrectly or
the battery is discharged.
If the battery is discharged, the following message appears:
"Please change battery".
Only use CR 2032 batteries; others can cause faults.

3.2 Preparing measurement
You require two test tubes to measure a parameter. Both test
tubes are vertical and are lled to the mark with test water. The
difference between reference tubes and measuring tubes is
important in the following.
The recesses/holes in the measuring device's delivered
packaging are suitable for rm and steady storage.
If indicators are used or the measurement, you perform the
actions in acc. with the indicator instructions before the
measurement. Please ensure here that you wear safety
glasses and observe the safety notes for handling hazardous
substances.
3.3 Operating
Button for switching on and off.
You switch between the individual parameters by pressing the
"Select" button.
The order is as follows: Ammonia, nitrite, nitrate, phosphate,
copper, silicon, chlorine, pH value.
Pressing the "OK" button again conrms the selected test.
After selecting and conrming the parameter to be measured,
the device automatically determines the length of the
measuring tube.
With the "Please extend measuring tube!" message the
measuring tube must be carefully pulled out by
hand until it engages.
Pulling out further would destroy the measurement device!
7
With the "Please slide in measuring tube!" message
you push the measuring tube in carefully with your hand
until it stops.
Ensure that there is nothing stuck in the measurement
openings. This could damage the optics.
"Ready for reference" appears when the measuring tube
is in the right position.
To homogenize the test water for the measurement and to
prevent air bubbles from forming on the lens, insert the
measuring tube into the reference tube (tube 1) and stir the
liquid lightly.
Pressing the "OK" button starts the measurement process
again.
The 3 seconds wait time is announced with the
"Please wait ..." prompt, which appears on the
"Ready for measurement" display.
To homogenize the test water and the respective indicator for
the measurement and to prevent air bubbles from forming on
the lens, insert the measuring tube into the test tube (tube 2)
and stir the liquid lightly.

process.
The measured value is shown after three seconds.
3.4 Cleaning after the measurement
You should rinse the measurement components and the lenses
in particular with distilled water after every measurement.
The lens can, if required, also be cleaned with a fuzz-free
cloth or a cotton bud.
No components must be removed for cleaning.
Insert the cotton bud on the side through the cut-outs of the
measuring tube and rub the lens clean on the bottom without
applying pressure. The end of the transparent rod can also be
cleaned.
3.5 Switching the device off
If the "OK" button is pressed longer than 3 seconds, the
device switches off completely and measurements already made
are lost.
Automatic device switch-off
If the device is not used for 6 minutes, it switches off automatically. Measured values are lost!
