4. Measuring
4.1. Basic Rules for Photometric Determinations
The precision and repeatability of a photometric determination depends greatly on the operator's technique. Please observe the following rules:
Always use clean utensils
Residues from previous measurements can falsify the results. All
utensils such as syringes, cuvettes or similar and the cuvette cap
must be rinsed with clean water after each measurement. Rinse the
cuvette with the sample 2 to 3 times before each measurement.
Position cuvettes correctly
Cuvettes must always be positioned in the same way. Keep the cuvette free of fingerprints and dry the outside of the cuvette before
inserting it into the cuvette adapter.
Wipe off condensation
If condensation occurs on the cuvette (cold sample in a warm environment), wipe it off and carry out the measurement as quickly as
possible.
Observe proper sampling
Take the water samples about 10 cm below the water surface and
about 50 cm from the edge of the pool. Allow as little time as possible to elapse between taking the sample and making the measurement.
Observe proper dosing and mixing
Use the 10 ml syringe for exact dosing of the sample. Rinse the syringe several times with the sample. When filling the syringe, make
sure that there are no air bubbles and that the volume is 10 ml.
The order in which sample and reagents are added to the cuvette
varies from method to method. If the reagents are added to the cuvette after the sample, special care must be taken to ensure that
the sample and the reagents mix well. For this purpose, carefully
turn the closed cuvette over, but do not shake it.
10 A-96.730.101 / 100519
Page 13
Chematest 30
Measuring
Observe reaction times
With most methods, the measurement can be carried out immediately after the reagents have been added and mixed with the sample. If a reaction time is required, this is indicated to the user on the
screen.
4.2. How To Use Reagents
Whenever possible, Swan supplies reagents in liquid form, as used
in professional laboratories. We believe that the disadvantage of
shorter shelf life is more than compensated for by the ease of use
compared to tablets or powders.
The OXYCON-DPD reagent is delivered in two small bottles to increase shelf life. One contains DPD as powder (DPD 1a), the other
contains the solvent (DPD 1b). Before use, fill the contents of DPD
1b into DPD 1a, close the bottle with the drop counter and shake
firmly until the DPD powder has completely dissolved. Write the
mixing date on the bottle. The prepared reagent can be stored at
room temperature for 2 months.
The reagents OXYCON START and OXYCON 2 have a shelf life of
at least 6 months. They will last a year if handled carefully and
stored at 5 °C. With the blister pack, all reagents can be taken out
of the case at once and placed in the refrigerator.
To dispense the necessary number of drops, hold the bottle at a 45°
angle. Before proceeding with the measurement, make sure that
the reagents are well mixed with the sample.
The Chematest 30 is calibrated against Swan's OXYCON reagents.
Accuracy may suffer severely, when reagents from other sources
are used.

4.3. Notes on Individual Methods
Free chlorine When free chlorine is determined in the presence of cyanuric acid,
two forms of chlorine are measured: free chlorine and chlorine
bound to cyanuric acid. To determine the disinfection capacity of
the water, the concentration of cyanuric acid must also be measured and the result of the chlorine determination must be corrected as follows:
Cyanuric acid 20 mg/l 30 mg/l 50 mg/l 70 mg/l
Percentage of free
chlorine in the measured value
50% 43% 26% 19%
Combined
chlorine
Ozone Ozone decomposes in a very short time and is usually only present
The method catalogue of the Chematest 30 contains two options
for measuring combined chlorine: with one cuvette or with two cuvettes. Apart from the fact that one or two cuvettes are used, the
two methods are identical. Measuring with only one cuvette is faster and requires less reagents. However, some standards require
measurement with two cuvettes. The selection of the method
should be based on the site-specific requirements.
in traces. It is essential to rinse the cuvette three times with the
ozone-containing water before filling in the actual sample. Carry out
the further steps as quickly as possible, but work meticulously.

4.4. Performing a Photometric Measurement
WARNING
Health hazard
For safe handling of the reagents, you must read and understand the corresponding Material Safety Data Sheets (MSDS).
These can be downloaded from www.swan.ch.
Explanation of
photometric
measurements
Starting a
measurement
The basic procedure is largely the same for all photometric measurements and is briefly outlined below. A photometric measurement consists of the following steps:
Step 1: Zero measurement
Step 2: The actual measurement
Step 3: Display and storage of the measured results. For de-
tails on the result screen, see example on 15.
The methods differ mainly in the following points:
Different reagents are required depending on the method.
Some methods require a reaction time. If this is the case for
the selected method, this will be indicated on the screen
during the measurement.
Some methods (e.g. combined chlorine) perform two different
measurements in a row and calculate the required values
from them.
To start a measurement, select the corresponding method from the
main screen. If it is not available there, select it from the method
catalogue.
The measurement itself is menu-driven. Follow the instructions on
the screen.

6.1. Photometer Verification
The verification kit contains two reference cuvettes (labeled “Low”
and “High”) with certified reference absorptions of approximately
0.3 and 1.5 and an additional cuvette for zero point determination.
The exact values are specified in the enclosed calibration certificate. The absorption values of the reference cuvettes simulate approximately 1 ppm and 4.5 ppm of free chlorine.

history
Prior to performing the first verification and after each recertification, the reference values for the cuvettes “Low” and “High” need to
be set in menu <Settings>\<Sensors> \ <Photometer>. The reference values are specified in the enclosed calibration certificate.
Before each use, check the expiration date on the calibration certificate. If the expiration date has passed, send the verification kit to
Swan for recertification.
To start a verification, navigate to <Menu>/<Maintenance>/
<Verification>/ <Photometer>. Select cuvette “Low” and follow the
instructions on the screen. Repeat the same procedure with the cuvette “High”.
Can be reviewed in <Menu>/<Data Storage>/<Ver. History>.
Up to 32 verifications are memorized. Then the oldest verification is
deleted to save the newest one (circular buffer).

If the fields ID and User contain the text "<Empty>", the assignment
of the attributes to the measurement was skipped by the user or deactivated under 4.2 Identification, p. 25.
Up to 2700 measurements are memorized. Then the oldest measurement is deleted to save the newest one (circular buffer).
1.2 Verification History
Photometer Displays previous photometer verifications. Each record includes
the following data:

3.1 Simulation
For test purposes a measurement can be made with one or both
LEDs on. The results are displayed as raw values in volts. In case
of problems in the field, Swan Support may ask for these values.
LED Green Performs a test measurement with the green LED on.
LED IR Performs a test measurement with the IR LED on.
Both LEDs Performs three consecutive measurements:
