Turb 430 IR/T Safety
2 Safety
This operating manual contains basic instructions that you must follow
during the commissioning, operation and maintenance of the meter.
Consequently, all responsible personnel must read this operating
manual carefully before working with the meter. The operating manual
must always be available within the vicinity of the meter.
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 in this operating manual are indicated by the
warning symbol (triangle) in the left column. The signal word (e.g.
"Caution") indicates the level of danger:
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.

Safety Turb 430 IR/T
2.1 Authorized use
This meter is authorized exclusively for carrying out turbidity
measurements in the field and laboratory.
The technical specifications as given in chapter 7 T
ECHNICAL DATA must
be observed. Only the operation and running of the meter according to
the instructions given in this operating manual is authorized. Any other
use is considered to be unauthorized.
2.2 General safety instructions
This instrument is built and inspected according to the relevant
guidelines and norms for electronic measuring instruments (see
chapter 7 T
It left the factory in a safe and secure technical condition.
Opening the photometer or adjustment, maintenance and repair work
must only be performed by specialist personnel authorized by the
manufacturer.
The only exceptions to this are the activities described in chapter
5M
AINTENANCE, CLEANING, DISPOSAL. Non-compliance results in the
loss of warranty claims.
Follow the points listed below when operating the photometer:
ECHNICAL DATA).
Function and
operational safety
! Follow the local safety and accident prevention regulations
! Observe the enclosed instructions of reagents and accessories
! Observe the regulations when dealing with dangerous substances
! Follow the operating instructions at the workplace
! Use only original spare parts.
The smooth functioning and operational safety of the meter can only be
guaranteed if the generally applicable safety measures and the specific
safety instructions in this operating manual are followed during
operation.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 7 T
ECHNICAL DATA.
If the instrument was transported from a cold environment to a warm
environment, the formation of condensate can lead to the faulty
functioning of the instrument. In this event, wait until the temperature of
the instrument reaches room temperature before putting the instrument
back into operation.

ba75507e03 07/2006
Turb 430 IR/T Safety
Safe operation 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 instrument must be taken out
of service and secured against inadvertent operation!
Safe operation is no longer possible if the meter:
! has been damaged in transport
! has been stored under adverse conditions for a lengthy period of
time
! is visibly damaged
! no longer operates as described in this manual.
If you are in any doubt, please contact the supplier of the instrument.
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.
Obligations of the
purchaser
The purchaser of this meter must ensure that the following laws and
guidelines are observed when using dangerous substances:
! EEC directives for protective labor legislation
! National protective labor legislation
! Safety regulations
! Safety datasheets of the chemical manufacturers.
