This operating manual contains basic instructions to
be followed in the commissioning, operation and
maintenance of the meter. Consequently, all
responsible personnel must read this operating
manual before working with the meter.
The operating manual must always be available in the
vicinity of the meter.
Authorized use
The photometer is authorized exclusively for
analyzing substances in water and aqueous solutions
using round cells or rectangular cells (special optical
glass).
Observe the technical specifications of the cells
according to chapter TECHNICAL DATA, in the
FUNCTIONAL DESCRIPTION document [on CD-ROM].
Any other use is considered unauthorized.
General instructions
The photometer is constructed and tested according
to the EN 61010-1 safety regulations for electronic
measuring instruments. It left the factory in a safe and
secure technical condition.
The smooth functioning and operational safety of the
photometer can only be guaranteed under the climatic
conditions specified in chapter TECHNICAL DATA, in the
FUNCTIONAL DESCRIPTION document [on CD-ROM] of
this operating manual.
Opening the photometer or adjustment, maintenance
and repair work must only be performed by personnel
authorized by the manufacturer.
The only exceptions to this are the activities described
in chapter MAINTENANCE, CLEANING, DISPOSAL. Non-
compliance results in the loss of warranty claims.
Follow the points listed below when operating the
photometer:
Follow local safety and accident prevention
regulations.
Observe the enclosed instructions concerning
reagents and accessories.
Observe the regulations when dealing with
dangerous substances.
Follow the operating instructions at the workplace.
Use only original spare parts.
Labeling of notes
indicates notes that you must read – for
your own safety, the safety of others and to
protect your meter from being damaged.
indicates notes that draw your attention to
special features.
Dangers of disregarding the safety instructions
Disregarding the safety instructions can adversely
affect the safety of both the user and the environment
as well as the equipment.
Non-compliance with the safety instructions will result
in the loss of any warranty claims.
Qualification of the personnel
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
ba77048e01 02/2014 7
Technical state of the meter
It is the responsibility of the operator to continuously
observe the overall technical condition (externally
recognizable deficits and damage as well as
alterations to the operational behavior) of the meter.
If safe operation is no longer possible, the equipment
must be taken out of service and secured against
inadvertent operation.
Safe operation is no longer possible if
the equipment has been damaged in transport
the equipment has been stored under adverse
conditions for a lengthy period of time
the equipment is visibly damaged
the equipment no longer operates as prescribed.
If you are in any doubt, please contact the supplier of
the photometer.

Commissioning
8ba77048e01 02/2014
– To switch on the photometer, open the cover.
The photometer performs a check (Self-Check) of the
entire system and then switches automatically to the
concentration measuring mode.
Self-check of the photometer
Automatic change to the measuring mode,
concentration

The photometer operates at an environmental
temperature of +5 °C to +40 °C. During transport from
cold to warm surroundings, condensation can form
resulting in the malfunction of the meter.
Before putting the photometer into service, wait until it
has adapted to the new environmental conditions
(see also chapter TECHNICAL DATA, in the FUNCTIONAL
DESCRIPTION document [on CD-ROM]).
Preparing the photometer
– Place the photometer on a hard, flat surface and
protect it against intensive light and heat.
Line operation
– Plug the original power pack into the socket on the
photometer
– Plug the power pack into the line socket
– Switch on the photometer (open the cover).
Battery operation
– Charge the battery for approx. 5 hours before the
initial commissioning. To do this:
Plug the original power pack into the socket on
the photometer
Plug the power pack into the line socket and
then the battery will be charged.
During battery operation or when the meter is at a
standstill for longer periods of time, the battery runs
down. This can result in your photometer no longer
being ready for operation.
When the following symbol is displayed, charge the
battery:

– Insert the round cell with barcode into the round cell
shaft until it clicks into place.
Align the line mark to the notch of the photometer.
The photometer reads the barcode of the round cell
and automatically selects the relevant method.
The measured value appears on the display.
If the select method menu is displayed, align the
line mark of the round cell or AutoSelector to the
notch of the photometer.

Align the line mark to the notch of the photometer.
The photometer reads the barcode and automatically
selects the relevant method.
– Insert the rectangular cell (vertically, to the right of
the slot). The measurement starts automatically.
Observe the position mark at the cell shaft.
If the select method menu is displayed, insert the
corresponding AutoSelector into the round cell
shaft.
If the "cell type" query appears,
select the relevant rectangular cell (10 mm, 20
mm, 50 mm) with 3or 28,

Zero adjustment
ba77048e01 02/2014 11
5
Zero adjustment is necessary
after changing the lamp
after the error message, PhotoCheck (AQA1)
occurs
on initial commissioning
if the photometer was mechanically stressed, e.g.
percussion, transport
if the ambient temperature changed by more than
5 °C since the last zero adjustment
at least every six months.
When performing the zero adjustment with a round
cell observe the following points:
Only use a clean, scratch-free round cell with
distilled water. A prepared zero cell is provided with
your photometer. In addition, a prepared zero cell
is contained in the scope of delivery of the
PhotoCheck (article 14693).
If the round cell is visibly contaminated, or at least
every 24 months, clean and refill it (minimum filling
level 20 mm). Then check the cell for scratches.
When performing the zero adjustment with a
rectangular cell observe the following points:
With rectangular cells, the adjustment must be
made using the same cell type (manufacturer) as
for the measurement. This is important because
glass of different manufacturers has different
absorption behavior. When changing the cell type
always repeat the zero adjustment with the new
type.
Clean the rectangular cell before performing the
zero adjustment and fill it with distilled water
(minimum filling level 20 mm).
For measurement, always insert rectangular cells
in the cell shaft with the same orientation as during
the zero adjustment (e.g. cell labeling always on
the left side).

Cleaning - Actions to take if a cell is broken
Do not rotate the photometer to pour out
the liquid!
The photometer has a draining mechanism under the
cell shaft that, when operated correctly, prevents any
liquid coming into contact with electronic components.
– Switch off the photometer (close the cover) and
disconnect it from the line power
– Let the liquid drain off
– Carefully remove any pieces of glass,
e.g. using
tweezers
– Carefully clean the cell shaft with a damp, lint-free
cloth
– Let the cell shaft dry

– Perform a photometer monitoring (see section
PHOTOMETER MONITORING (AQA1), in the
FUNCTIONAL DESCRIPTION document [on CD-
ROM]).

Maintenance, cleaning, disposal

The measuring instrument is sent out in a protective
transport packing.
We recommend: Keep the packing material in case you
have to send the measuring instrument back for service.
The original packing prevents the measuring instrument
from being damaged during transport.
Dispose of the measuring instrument as electronic
waste at an appropriate collection point. It is illegal to
dispose of it in household refuse.
Within the European Union, the batteries are removed
at a specialized treatment center at the instrument's end
of life. The instruments are taken to one of those
specialized treatment centers via the recycling system
set up for this purpose.
