Maintenance and servicing
The moisture analyser must be treated carefully and cleaned regularly.
This is a precision instrument.
Regularly dismantle the weighing pan and the weighing pan holder and
remove any dirt or dust from under the weighing pan and on the
balance housing with a soft brush or a soft, lint-free cloth, moistened
with a mild soap solution.
The balance pan and the holder can be cleaned under running water.
Take care to ensure that both parts are completely dry before they are
re-installed on the balance.
Regular maintenance of the moisture analyser by your Precisa service
DANGER
To facilitate maintenance work, the instrument must be
disconnected from the power supply. Also ensure that the
instrument cannot be reconnected to the power supply during the
work by anyone else.
Take care during cleaning that no liquid gets into the instrument. If
you spill any liquid onto the instrument, unplug it from the
electrical supply immediately. Do not operate the moisture
analyser again until you have had it checked by a Precisa service
engineer.
The connection ports on the back of the instrument may not come
into contact with liquids.
CAUTION
Never use solvents, acids, alkalis, paint thinners, scouring
powders or other aggressive or corrosive chemicals for cleaning
since these substances attack the surfaces of the instrument
housing and can cause damage.
