● Never use the instrument in an explosive atmosphere especially
when making current measurements.
#
CAUTION
● Before making measurements check that the range selector
switch is at a proper range position. Make sure to remove the
tips of the test leads from the circuit under test when changing
the measuring range during measurements.
● Do not apply voltage to the current or resistance ranges. It may
result in a fuse blow or instrument damage.
● Make certain to set the range selector switch to the OFF position
after every use.
● It is recommended that the range selector switch should be set
to the 250mA DC position to protect the instrument against the
possible shock or vibration in transit.
Note: Take good care not to make voltage measurements with
the range selector switch at the 250mA DC position. The
fuse may blow or instrument get damaged.
● Do not expose the instrument to the direct sun, extreme
temperature and humidity or dew fall for a long period. Also, care
must be taken not to give a shock to the instrument by dropping
or inadequate handling.
● Since the meter cover has been given an anti-static treatment
do not rub it strongly with a dry cloth. Where anti-static charges
are present on the meter window after it has been used for a
long period of time, causing the meter pointer to deflect in an
abnormal way, coat its surface with anti-static chemicals for
plastics or wipe it with a dilute solution of anti-static fluid as a
temporary measure.
