capacitance
at

files;
when
measuring
large
capacitance,
the
reading
takes
a
few
seconds
to
stabilize,
which
is
normal
when
measuring
large
capacitance.

Input
current
greater

mA
between
the
input
port
"COM"
and
"10

the
meter
will
display
the
current
value
with
large
de-component
on
the
LCD
according
to
the
magnitude
of
the
AC
/
DC
component.
Note:
1, Before the instrument is connected in series to the circuit to be tested, the power in
the circuit should be turned off first;
2, Maximum input current is 10 A( depending on the red meter pen insertion position),
too much current will burn out the internal fuse, be careful, each measurement time must
not be more than 10 seconds, too much current or too long measurement time will make
the instrument circuit heating, or even damage the instrument;
3. Do not connect the meter pen test pin parallel to any circuit when the red meter
pen is inserted in the "10 A" port, this will damage the fuse and meter.
4. After all the measurement operations are completed, the power supply should be
turned
off
first
and
then
the
connection
between
the
meter
pen
and
the
measured
circuit
should be disconnected.
