Rules
For
Safe Operation
. .warning
To avoid possible electric shock
or
personal
injury
,
and
to
avoid possible damage to the Meter or to the equipment
under test, adhere to the following rules:
Before using the Meter inspec t the case. Do not use the
Meter
if it is damaged or the case
(or part of
the case) is
removed. Look for cracks
or
missing plastic. Pa y
attention to the insulation around the connectors.
Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace
damaged
test leads with identical model number
or
electrical specifications before using the
Meter.
Do
not apply more than the rated voltage, as marked on
the Meter, between the terminals or between any
terminal and grounding.
The rotary switch should be placed in the right position
and
no any changeover
of
range shall be made
during
measurement
is conducted to
prevent damage
of the
Meter.
When the Meter working at an effective voltage over 60V
in DC or 30V
rms
in AC, special
care
should be
taken
for
-
there
is
danger of
electric shock.
Use the proper terminals, function, and
range
for your
measurements.
Do
not use or store the Meter in an environment of high
temperature,
humidit
y, explosive, inflammable and
strong magnetic field . The performance of the
Meter
may deteriorate after dampened.
When using the test leads, keep your fingers behind the
finger guards.
Disconnect circuit power
and
discharge all high-voltage
capacitors
before testing resistance, continuity, diodes,
current,
or capacitance.
Before measuring current, check the Meter's
fu
ses and
turn off power to the circuit before connecting the
Meter
to the circuit.
Replace the battery as soon as the
battery
indicator
11
Q

appears. With a low battery, the Meter might
produc
e
false readings that can lead to electric shock and
personal injury.
Remove test lead, t.

cable
and
test clip from the Me
ter and turn the Meter
power off before opening the Meter case.
When
servicing
the Meter
, use only
the same
model
number
or identical electrical specifications replacement
parts.
The internal circuit of the Meter
shall
not
be
altered
at
will to avoid
damage of
the
Met
er
and
any accident.
oft cloth
and
mild detergent shonld be used to clean the
surface of the Meter
when servicing. No
abrasive and
solvent should be used to prevent the surface
of
the Meter
from corrosion
damage and
accident.
The
Meter is suitable for indoor use.
Under the environment
with high +/-4kV) electrostatic
discharge
,
the
Me
ter ma
y
not
be
operated as normal
condition.
The user ma
y
require resetting the Meter.
Please take out the
batter
y when it is not being used for a
prolonged period to avoid damages to
the
Meter.
Please constantly check the battery as it may leak when it
has been using for some time, replace the battery as soon
as leaking appears. A leaking battery will
damag
e the Meter.
