Switch the unit on using the [ON/OFF] key.
The display shows the following:
Select the required test using the [MODE] key.
Scroll Memory (SM)
To avoid unnecessary scrolling for the required test method, the in-
strument memorizes the last method used before being switched off.
When the instrument is switched on again, the scroll list comes up with
the last used test method first.
The display shows the following:
Fill a clean vial with the water sample up to the 10 ml mark, screw
the cap on and place the vial in the sample chamber making sure that
the marks are aligned.
Press the [ZERO/TEST] key (see OTZ).
The "Method" symbol flashes for approx. 8 seconds.
The display shows the following:
After zero calibration is completed, remove the vial from the sample
chamber. The characteristic coloration appears after the addition of
the reagents.
Replace the cap on the vial and place in the sample chamber making
sure that the marks are aligned.
Press the [ZERO/TEST] key.
(For Countdown/reaction period see page 11)
The "Method" symbol flashes for approx. 3 seconds.
The result appears in the display.
The result is saved automatically.
Repeating the test:
Press the [ZERO/TEST] key again.
OTZ (One Time Zero):
The zero setting is held in memory until the instrument is switched
off. It is not necessary to perform a new zero each time, if the water
samples under test are from the same body of water and the conditions
of testing are the same.
The zero setting can be repeated each time if necessary.
Repeating the zero:
Press the [ZERO/TEST] key for 2 seconds.

1Prt – Transmitting stored data (to Printer or PC)
The IRIM (infrared interface modul) uses modern infrared technology to
transmit measurement data from the photometer to one of 3 optional
interfaces. These interfaces can be used to connect to a PC, a USB
printer1) or alternatively a serial printer2).
1) USB printer: HP Deskjet 6940 ; 2) All ASCII printer with serial interface
can be used. (or equivalent printer with HP PCL 3 to HP PCL 5)
Note: To print data, or to transmit to a PC, the optional IRIM (Infrared
Interface Module) is required.
The IRIM Module and the connected printer/PC must be ready. Press
the [MODE] key to start the transmitting, the instrument displays
“PrtG” (Printing) for approx. 1 second followed by the number of the
first data set and its transmission. All data sets will be transmitted one
after the other. After finishing the instrument switches to test mode.

Guidelines for photometric measurements
1. Vials, caps and stirring rods should be cleaned thoroughly after each analysis to prevent
interference. Even minor reagent residues can cause errors in the test result.
2. The outside of the vial must be clean and dry before starting the analysis. Clean the
outside of the vials with a towel to remove fingerprints or other marks.
3. Zero calibration and test must be carried out with the same vial as there may be slight
differences in optical performance between vials.
4. The vials must be positioned in the sample chamber for zeroing and test with the mark
on the vial aligned with the mark on the instrument.
5. Always perform zeroing and test with the vial cap tightly closed. Only use the cap with
a sealing ring.
6. Bubbles on the inside wall of the vial lead to incorrect measurements. To prevent this,
remove the bubbles by swirling the vial before performing the test.
7. Avoid spillage of water into the sample chamber because this can lead to incorrect test
results.
8. Contamination of the transparent cell chamber can result in wrong readings. Check at
regular intervals and – if necessary – clean the transparent cell chamber using a moist
cloth or cotton buds.
9. Large temperature differences between the instrument and the environment can lead
to errors – e.g. due to the formation of condensation in the cell chamber or on the vial.
10. To avoid errors caused by stray light do not use the instrument in bright sunlight.
11. The reagents must be added in the correct sequence.
Method notes
• Prior to measurement ensure that the sample is suitable for analysis (no major interferences)
and does not require any preparation i.e. pH adjustment, filtration etc.
• Different Refill Packs available on request.
• Reagents are designed for use in chemical analysis only and should be kept well out of
the reach of children.
• Ensure proper disposal of reagent solutions.
• Material Safety Data Sheets are available on request

sample.
Close the vial tightly with the cap and invert several times to mix the
contents (20 sec.).

are aligned.
Press the [ZERO/TEST] key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/l free Chlorine.
b) total Chlorine
Remove the vial from the sample chamber.
Rinse the vial and the cap several times and then fill the vial with 10 ml
of water sample (Note 2 and 3).
Add the contents of one Chlorine Total-DPD/F10 Powder Pack
(blue color marking ) straight from the foil into the water
sample.
Close the vial tightly with the cap and invert several times to mix the
contents (20 sec.).
Place the vial in the sample chamber making sure that the marks
are aligned.
Wait for a reaction period of 3 minutes.

> 2 – 3 mg/l: ± 0.20 mg/l
> 3 – 3.5 mg/l: ± 0.30 mg/l
Notes:
1. Vial cleaning:
As many household cleaners (e.g. dishwasher detergent) contain reducing substances,
the subsequent determination of Chlorine may show lower results. To avoid any meas-
urement errors, only use glassware free of Chlorine demand.
Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) for
one hour, then rinse all glassware thoroughly with deionised water.
2. For individual testing of free and total Chlorine, the use of different sets of glassware is
recommended (EN ISO 7393-2, 5.3).
3. Do not use the same sample vial for free and total chlorine without thoroughly rinsing
the vial between the two different tests.
4. Preparing the sample:
When preparing the sample, the lost of Chlorine, e.g. by pipetting or shaking, must be
avoided. The analysis must take place immediately after taking the sample.
5. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagents
therefore contain a buffer for the pH adjustment.
Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before
the reagent is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).
6. Exceeding the measuring range:
Concentrations above 2 mg/l Chlorine can lead to results showing 0 mg/l. In this case,
the water sample must be diluted with water free of Chlorine and the measurement
repeated.
7. Oxidising agents such as Bromine, Ozone etc. interfere as they react in the same way as
Chlorine.
