Safety
This Operating Instructions Manual contains fundamental information that should be observed in
connection with the installation, start-up, operation and maintenance of the instrument in connection
with the sensor. Therefore, it is absolutely vital for the user to read this manual completly prior to
working with it.
The symbol
„General Warning“ indicates special warnings in the manual.
User qualification
The device has been designed for analytical measurements. It is assumed that the user/operator and
the maintenance personnel have the proper professional skills and experience to know the specific
properties of analytical measuring systems, master the safe handling of chemicals, for example, in the
maintenance of electrodes/sensors, and can assess any dangers and risks resulting thereof. The user
must ensure that the national legislation and procedures concerning the maintenance of industrial
health and safety standards, the accident preventions and the handling of chemicals are observed.
Installation and getting started
The perfect functioning and operational safety of the instrument can only be maintained under the
climatic conditions specified in the
chapter
„Specifications“ of this manual. When the instrument is
moved from cold to warm surroundings, condensate may occur and interfere with the functioning of the
instrument. In such case, the user should wait until the temperature of the instrument has adapted to
the ambient temperature before using the instrument again.
Use the sensor and interface cables recommended by the manufacturer only. For the sensors and ac-
cessories, the instructions and regulations given in the respective operating instructions manuals and
specification sheets will apply. The instrument can only be operated with the battery specified in the
chapter
„Specifications”.
Be careful when connecting other instruments (e. g. via interface). Connections with external instru-
ments may cause not permissible potentials inside the instrument (e. g. connections between GND and
earth). These potentials may result in operational influences or malfunctions in the instrument itself or
the external devices connected.
Proper usage
The device and the sensor are intended for measuring and documentation of analysis parameters.
Taking into consideration the specifications, operating and using the unit for this application is the
proper usage. Any application beyond this and individual modifications or extensions are improper and
will lead to loss of entitlement to the warranty. When connecting the unit with electro-chemical sensors,
always take into account their life and natural wear as this may result in malfunctioning of the
measuring system and the regulation or control associated therewith. The user must take suitable
measures to limit harmful effects of such malfunctioning.
General safety instructions
The complete device has been manufactured and tested in accordance with the relevant guidelines and
standards for electronic measuring equipment. It has left the factory in technically unobjectionable
condition.
The perfect functioning and operational safety of the instrument and the accompanying components will
only be ensured if the user observes the normal safety precautions as well as the specific safety guide-
lines stated in the present manual and in the relevant operating instruction manuals of the components
contain replaceable components (exception of the battery) and must be opened for repair by proprietary
workshops only. If there is reason to assume that the instrument can no longer be employed without a
risk, it must be set aside and appropriately marked to prevent further use. The safety of the user may be
endangered, e. g. if the instrument or one of its components:
shows visible damage
no longer operates as specified
has been stored over a longer period under unsuitable conditions
has been subjected to difficult conditions during transport
If in doubt, please contact your supplier and sent back the instrument to the manufacturer for repair and mainte-
nance.
