Measuring
capacitance
&
In
order
to
avoid
any
damage
to
instrument
or
measured
equipment,
before
measuring
capacitance,
cut
off
all
power
supplies
of
the
circuit
being
measured
and
fully
discharge
all
high-voltage
capacitors.
Use
DC
voltage
to
confirm
the
capacitor
is
discharged.
The capacitance
ranges
of
the
instrument
are namely
10.000nF,
100
.00nF, 1000.
0nF,
10.000µF, 100.00µF
and
1000.
0µF,
lOmF,
lOOmF
.
Measure capacitance:
1. Turn
the
rotary switch
to
_
-I
I-gear
.
2.
Connect
the
black
test
pen
and
the
red
test
pen
to
COM
input
socket
and
-11-
input
socket
.
3. Use
both
ends
of
the
test
pen
to
measure
the
capacitance
of
the
capacitor
to
be
measured,
and
read
the
measured
value from
the
LCD
display.
Note:
(1) When measuring large capacitance, a period
time
is
required
to
achieve a stable reading.
(2)
When measuring capacitance with polarity,
note
the
corresponding
polarity,
to
avoid
any
damage
to
the
instrument.
3.2.6 Measuring frequency
&
It
·
is
not allowed to measure any voltage higher
than 250V
DC
or
AC
rms, to avoid electric shock
and/or
damaged instrument.
Measure frequency:
1.
Turn
the
rotary switch
to
HZ%,
and
press "Hz%" key
to
switch
between
HZ
and
% function.
2.
Connect
the
black
test
pen
and
the
red
test
pen
to
COM
input
socket
and
Hz
input
socket.
3. Use
both
ends
of
the
test
pen
to
measure
the
frequency
of
the
circuit
to
be
tested
.
4. Read
the
measured
frequency
from
the
LCD
display.
3.2.7 Mea~uring
current
& When the open-circuit voltage to the ground exceeds
250V, do not measure
the
current on the circuit.
If
the
fuse
is
burnt during measurement, you are likely
to
damage the instrument or hurt yourself.
In order to avoid any damage to the instrument
or the measured equipment, before measuring current,
please check the fuse
of
the instrument first. During
measurement,
use
correct input socket, function gear
and range. When the test pen
is
inserted onto the
current input socket, do not bridge the other end
of
the
test pen
to
any circuit in parallel.
