1.3 Warning and safety information
®
The TitroLine
7500 KF 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 contained 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 titrator TitroLine
for instance, that work on electrical equipment must only be performed by qualified specialists.
In the case of nonobservance of these provisions the titrator TitroLine

danger: electrical accidents of persons or fire hazard. Moreover, in the case of unauthorised
intervention in the titrator TitroLine
caused damage, the warranty will become void.
Prior to switching the device on it has to be ensured that the operating voltage of the titrator TitroLine® 7500
KF matches the mains voltage. The operating voltage is indicated on the specification plate. Nonobservance of
this provision may result in damage to the titrator TitroLine® 7500 KF or in personal injury or damage to
property.
If it has to be assumed that safe operation is impossible, the titrator TitroLine
operation and secured against inadvertent putting to operation. In this case please switch the titrator TitroLine
7500 KF off, pull plug of the mains cable out of the mains socket, and remove the titrator TitroLine
from the place of work.
Examples for the assumption that a safe operation is no longer possible,

For reasons of safety, the titrator TitroLine
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 titrator TitroLine
7500 KF are experts in the handling of substances used in the environment and in titrator TitroLine
or that they are supervised by specialised persons, respectively.
During all work with titration solutions: ! Please wear protective glasses! !

For the use of liquids with high vapour pressure or (mixture of) substances not being mentioned in chapter 1.1
as allowed substances, the safe and proper operation of the titrator TitroLine
by the user.
When the piston moves upwards within the cylinder, 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 non-
admitted liquids are being used, the materials of the titrator TitroLine
