Installation of the burette

Note the following points so that the instrument will operate perfectly and have a long
service life.
• Place the instrument firmly on an even surface. Do not push any objects under the
instrument.
• The ambient temperature must be 15 to 40 °C (60 to 104 °F).
• The relative humidity should be less than 80%; moisture should not condense on the
instrument.
• A minimum clearance of 15 cm (5.9 in.) must be ensured above and on all sides of the
device; this allows the air to circulate and prevents overheating of the electric parts.
The dosage arm of the stepper motor must be able to move freely.
• Do not operate or store the instrument in extremely dusty, humid or wet locations.
• Make sure that no liquids enter the instrument and immediately wipe away any liquids
that contact the instrument.
• Protect the instrument against vibrations, direct sunlight, corrosive gases as well as
strong magnetic and/or electric fields.
• Only use genuine replacement parts and accessories.
The instrument must be serviced by the manufacturer's service department at the
prescribed intervals.
The burette dispenses the titrant, a Sodium Hydroxide (NaOH) base that, depending on
the area of application, is either 0.1 M or 0.5 M.
The burette comprises the syringe, stepper motor and valve. The stepper motor and valve
are already installed in the TitraLab; the syringe has to be installed by the user.
Risk of injury to pinch points and cuts
Make sure that the titrator is never used/operated without the syringe cover.
Make sure that the system is only assembled by qualified and trained personnel.
Warning against system damage
Make sure that the syringe is never operated without the attachment sleeve.
Only use genuine replacement parts and accessories.
The instrument must be serviced by the manufacturer's service department at the prescribed
intervals.
Note: Make sure that you do not misplace the attachment sleeve for the syringe. It is not provided
with a new syringe.
1. Push the syringe piston into the syringe body.
Slide the attachment sleeve fully onto the syringe so that the narrow end points
toward the piston.
2. Remove the syringe cover by unscrewing it.
