exit this mode and “ MAX ” / ” MIN ” symbol disappear on display. This button do not effect on
diode and continuity test function, capacitance measurement, frequency measurement.
2.2 Check the 9-volt battery.
If the battery is weak, a “
" symbol will appear on the left of the display. It means that the
battery should be replaced.
2.3 DC and AC Voltage measurement
1)Connect the black test lead to "
COM
" socket and red test leads to the "
VOLT
" socket.
2)Set the selector switch to “
VOLT DC
” or “
VOLT AC
” position to select DCV or ACV measuring
mode.
3)Connect the probes across the source or load under measurement.
2.4 DC and AC Current measurement
1)Connect the black test lead to "
COM
" socket and red test leads to the "
µA
/
mA
" socket.
2)For measurement up to 600mA. Set the selector switch to “
AC/DC µA
” or “
AC/DC mA
”
position and press
SELECT
button to select DC or AC current measuring mode.
3)For current measurement from 600mA to 10A, connect the red test lead to "
10A
" socket. Set
selector switch to “
AC/DC 10A
” position and press
SELECT
button to select DC or ACA
measuring mode.
4)Connect the probes across the source or load under measurement.
Note: Not to measure a current in a circuit with voltage more than 250V.
2.5 Resistance measurement
1) Connect the black test lead to "
COM
" socket and red test leads to the "
Ohm
" socket.
2) Set the selector switch to "
Ohm
/ / / /
CAP
" position, and press
SELECT
button to
select resistance measuring mode.
3) Connect the probes across circuit to be tested.
Caution: Ensure that the circuit to be tested is "dead".
Max. input over-load: 250V RMS. and<10sec.
2.6 Diode, continuity test
1) Connect the black test lead to "
COM
" socket and red test leads to the "
/
" socket.
2) Set the selector switch to "
Ohm /
/
/ CAP
" position and press
SELECT
button
to select Diode
or continuity
test mode.
3) Connect the black and red test probe to the cathode (-) and anode (+) ends of diode to be
tested respectively.
4) Read the forward voltage drop (junction) value from the display. If reverse connected the
probes to diode, display shows over-load.
5) In Continuity test, the beeper sounds continuously if the resistance is less then
120
Ω
approximately.
Caution: Ensure that the circuit to be tested is "dead".
Max. input over-load: 250V RMS. and<10sec.
2.7 Capacitance measurement
1) Before testing, discharge the capacitor by shorting its leads together. Use caution in handing
capacitors because they may have a charge on them of considerable power before
discharging.
2) Connect the black test lead to "
COM
" socket and red test leads to the "
CAP
" socket.
3) Set the selector switch to "
Ohm /
/
/ CAP
" position and press
SELECT
button
to select capacitance measuring mode.
