Safety
Target group The meter was developed for work in the field and in the laboratory.
Thus, we assume that, as a result of their professional training and
experience, the operators will know the necessary safety precautions
to take when handling chemicals.
The personnel responsible for the commissioning, operation and
maintenance must have the necessary qualifications for this work. If the
personnel do not have the required skills they have to be instructed.
Furthermore, it must be ensured that the personnel read and
completely understand the present operating manual.
Safety instructions Safety instructions point out dangers:
Caution
indicates instructions that must be followed precisely in order to
avoid the possibility of slight injuries or damage to the instrument
or the environment.
Safe operation
Caution
Danger of eye damage by visible and invisible LED radiation. In
the cell shaft of the Turb 430 IR there are light emitting diodes
(LED) of the 1M class. Do not look at the radiation using optical
instruments. With normal, authorized use there is no hazard.
Display and socket field

2Insert the cell so that it is positioned on the bottom of the cell
shaft.
The cell is ready to be measured.
3Align the cell (see below).
1Clean the cell.
2 Insert the cell.
3Align the cell:
Press and hold the <START/ENTER> key.
Slowly and in small steps rotate the cell by one complete
rotation (by 360 °).
After each step wait for a short time until the displayed
measured value is stable.
Turn the cell back to the position with the lowest measured
value.
4 Release the <START/ENTER> key.
Measurement starts. The measured value is displayed.

Note
To keep the drift as low as possible, the time for aligning the cell while
pressing and holding the <START/ENTER> key is limited to 30
seconds. After this time, the meter starts measuring automatically.
Marking a cell To be able to quickly bring a cell into the optimum position, it is helpful
to mark the optimum position of the cell once it is determined. This
shortens each measurement or calibration procedure with this cell
considerably.
The marking can, e. g., be done on a label on the cap of the cell.
Measuring turbidity The outside of the cell always has to be clean, dry, and free of
fingerprints and scratches. Clean the cell before starting to measure.
Only hold the cells by the top or by the black light protection cap.
1Rinse out a clean cell with the sample to be measured:
Pour approximately 10 ml sample into the cell. Close the cell
and rotate it several times before throwing the sample away.
2 Repeat the rinsing procedure twice more.
3Fill the cell with the sample to be measured (approx. 15 ml).
Close the cell with the black light protection cap.
4 Clean the cell.
5Insert the cell.
6 Align the cell:
Marked cell
– Align the marking on the cell cap with the marking on the
cell shaft.
– Press and for a short time hold the <START/ENTER>
key until the measured value is displayed.
Unmarked cell (see page 9)
– Press and hold the <START/ENTER> key.
– Slowly and in small steps rotate the cell by one complete
rotation (by 360 °). After each step wait for a short time
until the displayed measure value is stable.
– Turn the cell back to the position with the lowest
measured value.
7Release the <START/ENTER> key.
Measurement starts. The measured value is displayed.

Maintenance The meter is almost maintenance-free.
The only maintenance task is replacing the batteries or accumulator
pack.
Caution
Make sure the poles of the batteries are the right way round. The
± signs on the batteries must correspond to the ± signs in the
battery compartment.

Cleaning Occasionally wipe the outside of the meter with a damp, lint-free cloth.
Disinfect the housing with isopropanol as required.
Caution
The housing components are made out of synthetic materials
(polyurethane, ABS and PMMA). Thus, avoid contact with acetone
and similar detergents that contain solvents. Remove any
splashes immediately.
Cleaning the cell shaft If liquid is in the cell shaft (e.g. due to a spilled cell), clean the cell shaft
as follows:
Cleaning the cells Cells have to be clean, dry, and free of fingerprints and scratches.
Therefore, clean them regularly:
Note
Scratches in the glass change the optical characteristics of the cell and
falsify the measured value. For this reason, never use scratched cells!
1Open the battery compartment:
– Unscrew the two screws (1) on the underside of the meter,
– Remove the lid of the battery compartment (2).
2 If necessary, take four old batteries out of the battery
compartment.
3Insert four batteries (3) in the battery compartment.
4 Close the battery compartment and fix it with the screws.
1Switch the Turb 430 IR/T off and pull out the power plug.
2 Rinse the cell shaft with distilled water.
1Clean the cells inside and out with hydrochloric acid or
laboratory soap.
2 Rinse out several times with distilled water.
3Let them dry in the air.
4 Only hold the cells by the top or by the light protection cap so
that the optical path is not impaired.
5Before measuring, clean the cell with the enclosed cleaning
cloth.
