equipment appropriate to the chemicals that are handled.
Refer to the current safety data sheets (MSDS/SDS) for
safety protocols.

W A R N I N G
Pacemaker precautions. If electromagnetic interference
(EMI) occurs, it can either:
• Stop the stimulating pulses from the pacemaker that
control the rhythm of the heart.
• Cause the pacemaker to supply the pulses irregularly.
• Cause the pacemaker to ignore the rhythm of the heart
and supply pulses at a set interval.
Current research shows that cellular devices are not a
significant health problem for most pacemakers wearers.
However, persons with pacemakers should use precautions
to make sure that their device does not cause a problem.
Keep the device a minimum of 20 cm (7.9 in.) from the user.
CAUTION
Electromagnetic radiation hazard. Make sure that the
antenna is kept at a minimum distance of 20 cm (7.9 in.)
from all personnel in normal use. The antenna cannot be co-
located or operated in conjunction with any other antenna or
transmitters.
6.1 Routine operation
CAUTION
Burn Hazard. Do not put a finger in an opening in the
heating block. Close the protective cover before increasing
the temperature of the heating block, and always keep the
protective cover closed during operation.
CAUTION
Burn Hazard. Sample cells are hot. Wear thermal insulating
material (e.g., gloves or finger cots). Do not remove a
sample cell that is greater than 80 °C. Do not put a sample
cell that is greater than 80 °C in a colorimeter.
CAUTION
Chemical Hazard. If a sample cell breaks, do not let the
liquid touch skin. Use a fume hood as necessary to remove
chemical fumes.
CAUTION
Chemical exposure hazard. Dispose of chemicals and
wastes in accordance with local, regional and national
regulations.
NOTICE
To prevent sample cell and instrument damage, keep the openings in
the heating block dry. Dry the outside of sample cells fully.
NOTICE
To prevent instrument damage, immediately disconnect power if an
accidental spill occurs or a sample cell breaks, then clean the
instrument. Refer to Clean the instrument on page 12.
NOTICE
Do not cover the ventilation slits in the protective cover. The instrument
and sample cells may become too hot and decrease the accuracy of
measurement.
1. Prepare the test sample cells as specified in the analysis procedure.
2. Close the sample cells with the cap.
3. Dry the outside of the sample cells fully.
4. Turn the instrument on and open the protective cover. The last
temperature program(s) selected is shown on the display.
5. If using 16 mm tubes with a heating block with 20 mm openings, put
reducing adapters in the openings.
6. LT 200: Put the test sample cells in the correct heating block and
close the protective cover.
7. Select the correct temperature program (and digestion period if
applicable) using the keys, then push Start. Refer to Stored
