General maintenance
Besides the hazards mentioned above, dirt or moisture in
the terminals can also distort the readings. The cleaning
procedure is outlined below:
1 Turn the instrument off and remove the test leads.
2 Turn the instrument over and shake out any dirt that may
have accumulated in the terminals.
3 Wipe the case with a damp cloth and mild detergent — do
not use abrasives or solvents containing benzine, benzene,
toluene, xylene, acetone or similar chemicals. Also, do not
spray cleaner liquid directly onto the instrument, because
it may seep into the case and cause damage. Wipe the
contacts in each terminal with a clean swab moistened in
alcohol.
4 Make sure the instrument has dried completely before
using it.
CAUTION
Repairs or services which are not covered in this manual should only
be performed by qualified personnel.
WARNING
Make sure that the terminal connections are correct for a particular
measurement before making any measurement. To avoid damaging the
instrument, do not exceed the rated input limit.
WARNING
To avoid electrical shock or damage to the instrument, prevent water
from getting inside the case.
