2 Safety Instructions

2.1 General safety instructions

Please read carefully!
The Titrette® can be used in combination with hazardous materials, work processes and equipment.
However, the operating manual cannot cover all of the safety issues that may occur in doing so. It is
the user's responsibility to ensure compliance with the safety and health regulations and to specify
the corresponding restrictions before use.
1.
Every user must read and understand this operating manual before operation.
2.
Follow the general hazard instructions and safety regulations (e.g., wear protective clothing,
eye protection, and protective gloves).
3.
Observe all specifications provided by reagent manufacturers.
4.
Do not operate the instrument in potentially explosive atmospheres.
5.
Use the instrument only for titrating liquids, with strict regard to the defined limitations of use
and operating limitations.
Comply with the operating exclusions (see Operating Exclusions, p. 53)!
If in doubt, contact the manufacturer or supplier.
6.
Always perform work in a manner that does not endanger yourself or other people. Avoid
splattering. Only use suitable vessels.
7.
Never turn the hand wheels when the titration tube is sealed with the cap.
8.
Never remove the titration tube while the glass cylinder is filled.
9.
Reagents can accumulate in the cap of the titration tube. Therefore, clean regularly.
10.
To avoid tipping over, use a bottle stand for small bottles.
11.
Never carry the instrument by the housing when it is mounted to a reagent bottle. Breakage or
loosening of the instrument from the reagent bottle may lead to personal injury.
12.
Never use force.
13.
Use only original accessories and original replacement parts. Do not make any technical modi-
fications. Do not dismantle the instrument any further than is described in the operating man-
ual!
14.
Always check that the instrument is in proper working condition before use. The user can
come into contact with media if the instrument has been insufficiently cleaned or inspected. If
there is a sign of a potential malfunction (e.g., piston difficult to move, sticking valves or leak-
age), immediately stop titration and consult Troubleshooting, p. 83. Contact the manufac-
turer, if necessary.
15.
The installed 1.5 V micro-batteries are not rechargeable!

2.2 Function

The Titrette® bottle-top burette with electronic digital display is used to titrate aqueous and non-
aqueous titration media (e.g. alcoholic KOH) up to a concentration of max. 1 mol/l. (See Recom-
mended application range, p. 54). Thanks to a high precision measurement system, even the close
tolerances of Class A for glass burettes can be adhered to. The instruments are marked DE-M.
