Warning and safety information

The TITRONIC

universal

Piston Burette corresponds to protection class II. It was manufactured and

tested according to DIN EN 61 010, Part 1, Protective Measures for Electronic Measurement Devices and
has left the factory in an impeccable condition as concerns safety technology. In order to maintain this
condition and to ensure safe operation, the user should observe the notes and warning information con-
tained in the present operating instructions. Development and production is done within a system which
meets the requirements laid down in the DIN EN ISO 9001 standard.

For reasons of safety, the TITRONIC

universal

Piston Burette must be opened by authorised persons

only; this means, for instance, that work on electrical equipment must only be performed by qualified spe-
cialists.

In the case of nonobservance of these provisions the TITRONIC

universal

Piston Burette may

constitute a danger: electrical accidents of persons or fire hazard. Moreover, in the case of unau-
thorised intervention in the TITRONIC

universal

Piston Burette as well as in the case of negli-

gently or deliberately caused damage, the warranty will become void.

Prior to switching the device on it has to be ensured that the operating voltage of the TITRONIC

universal

Piston Burette matches the mains voltage. The operating voltage is indicated on the specification plate.
Nonobservance of this provision may result in damage to the TITRONIC

universal

Piston Burette or in

personal injury or damage to property.

If it has to be assumed that safe operation is impossible, the TITRONIC

universal

Piston Burette has to

be put out of operation and secured against inadvertent putting to operation. In this case please switch the
TITRONIC

universal

Piston Burette off, pull plug of the mains cable out of the mains socket, and remove

the TITRONIC

universal

Piston Burette from the place of work.

Examples for the assumption that a safe operation is no longer possible,

the package is damaged,

the TITRONIC

universal

Piston Burette shows visible damages,

the TITRONIC

universal

Piston Burette does not function properly,

liquid has penetrated into the casing.

The TITRONIC

universal

Piston Burette must not be stored or operated in humid rooms.

For reasons of safety, the TITRONIC

universal

Piston Burette must only be used for the range of appli-

cation described in the present operating instructions.

In the case of deviations from the intended proper use of the device, it is up to the user to evaluate the
occurring risks.

The relevant regulations regarding the handling of the substances used have to be observed:

The Decree on Hazardous Matters, the Chemicals Act, and the rules and information of the chemicals
trade. It has to be ensured on the side of the user that the persons entrusted with the use of the
TITRONIC

universal

Piston Burette are experts in the handling of substances used in the environment

and in the TITRONIC

universal

Piston Burette, or that they are supervised by specialised persons,

respectively.

During all work with titration solutions:

Please wear protective glasses!

When the piston moves upwards within the cylinder, owing to the design of the system, a microfilm of
dosing liquid or titration solution will always remain adhered to the inner wall of the cylinder, but this has no
influence on the dosing accuracy. This small residue of liquid, however, may evaporate and thus penetrate
into the zone underneath the piston, and if inadmitted liquids are being used, the materials of the
TITRONIC

universal

Piston Burette may be dissolved or corroded (please refer also to "Maintenance and

Care").

The TITRONIC

universal

Piston Burette is equipped with integrated circuits (EPROMs). X rays or other

high-energy radiation may penetrate through the device’s casing and delete the program.

Please note also the corresponding operating instructions for the devices to be connected.
