!
The moisture analyser is used to analyse the moisture content of materials.
This instrument must be used exclusively for this purpose. Any other usage
may cause a risk to personnel, damage to the instrument or other material
damage.
!
The moisture analyser should be used mainly for the drying of aqueous
substances.
!
The moisture analyser may not be used in a hazardous area.
!
Do not use the moisture analyser in an explosive environment.
!
The operation and maintenance of the moisture analyser is restricted to
trained competent specialist staff.
!
Carefully read this operation manual before setup and commissioning, even if
you are already familiar with KERN instruments.
!
Never make any modifications or design changes to the equipment
whatsoever. Always use original spare parts and accessories.
!
Make sure that liquids cannot pen
etrate the interior of the device, the terminals
at the rear of the device and the connected peripherals (such as printer, PC).
If you spill liquid on the device, disconnect it immediately.
Afterwards do not operate the moisture meter and have it checked by a
competent KERN stockist before any further use.
Hazards during and after measuring
!
Ensure correct installation of all components, see chap. 7.3
!
Careful when removing the sample. The sample itself, the sample dish and the
heating unit may be very hot.
!
Use the sample retainer at all times as it allows safe working and prevents
burns.
!
Individual parts of the case (e. g. the ventilation grids) may heat up
considerably during operation.

14 DAB-BA-e-1813
The moisture analyser operates using heat!
+Maintain sufficient space in the environment of the instrument to
prevent heat build-up (distance from the instrument 20cm,
upwards 1m).
+The heat extractor of the sample must never be covered, blocked,
taped up or altered in any other way.
+Never place combustible materials on, under or next to the
instrument, as the environment of the instrument heats up to a
high temperature.
+Careful when removing the sample. The sample itself, the sample
dish and the heating unit may be very hot.
Fire or explosion
+Explosive, easily flammable samples and samples that go into a
chemical reaction when subjected to heat, may not be analysed
with the moisture analyser.
+If in doubt, conduct a risk analysis.
+Select a drying temperature for samples of this kind that is low
enough to prevent ignition or explosion.
+Wear safety goggles.
Substances that contain toxic or corrosive ingredients,
produce toxic gases when drying, cause irritation (eyes, skin,
airways), induce nausea or result in death
+Sample materials emitting toxic substances must be dried with a
special extraction system in place. Create an environment that
prevents the inhalation of vapours hazardous to health.
Substances that liberate corrosive gases when heated up (such as
acids)
+In that case, work with smaller sample amounts as the liberated
gases may condense on cooler casing parts and later cause
corrosion.
