7.1 Maintenance and servicing
The MRS 120-3 moisture analyzer must be treated carefully and
cleaned regularly. This is a precision instrument
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 MRS 120-3 moisture
analyzer again until you have had it checked by a KERN service
engineer.
The connection ports on the back of the instrument may not come
into contact with liquids.
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.
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.
Regular maintenance of the MRS 120-3 moisture analyzer by your
KERN service agent will guarantee unrestricted functioning and
reliability over many years and will extend the lifespan of the
instrument.
