4-2 DC/AC Voltage Measurements
WARNING
Maximum Input Voltage at DC/AC Voltage Range is 600V
AC/DC. Do not attempt to take any voltage measurement
that may exceed to avoid electrical shock hazard and/or
damage to this instrument.
(1) Connect red test lead to “ V
Ω
” terminal and black test lead to
“ COM ” terminal.
(2) Set Range Switch to
V
or
V
range.
(3) Connect the test leads IN PARALLEL to the circuit being
measured.
(4) Read the Voltage value on LCD.
4-3 DC/AC Current Measurement
WARNING
Continuous measurements can be applied in 10A Range.
less that 30 seconds per measurements can be applied in
20A Range.
(1) Connect red test lead to the “mA/uA“ Terminal for Current
measurements up to 320mA. (For measuring Current between
320mA to 20A, Connect red test lead to “20A” terminal. )
Connect black test lead to “COM” terminal.
(2) Set Range Switch to desired A range. and press AC/DC switch
to DC/AC function.
(3) Cut the power to the circuit to be tested and Connect the
instrument IN SERIES with the circuit with the black test lead on
the negative “
－
” side and the red lead on the positive “
＋
“ side
being measured.
(4) Apply power and read the Current value on LCD.

4-4 Diode Tests
WARNING
Before taking any in-circuit measurement, remove power from
the circuit being tested and discharge all capacitors in the circuit.
(1) Connect red test lead to the " V
Ω
" terminal and black test lead to
the " COM" terminal.
(2) Set range switch to the diode test "
" position and press
／
button to
function.
(3) Connect the red test lead to the anode side and black test lead to
the cathode side of the diode being tested.
(4) Read forward voltage (Vf) Value on LCD.
(5) If the polarity of test leads are reversed with diode polarity (3), the
digital reading should nearly equal to the reading in the open
circuit condition. This can be used for distinguishing anode and
cathode poles of a diode.
4-5 Resistance Measurement
WARNING
Before taking any in-circuit resistance measurement, remove
power from the test circuit being tested and discharge all
Capacitors.
(1) Connect red test lead to “ V
Ω
“terminal and black test lead to
“ COM” terminal.
(2) Set Range Switch to
Ω
range.
(3) Connect test lead to the circuit being measured and read the
resistance Value on LCD.
