position and connect test leads in series with the
load under measurement.
3.2.3 Put down the "AC/DC" when measuring the
current. Meter will be transformed between DC
and AC range.
3.2.4 If you need data hold when measuring, you
can put on “HOLD”, it will hold the reading; if you
put the button again, data hold will not continue.
3.2.5 When only the figure“1”is displayed, it
indicates overrange situation and the higher range
has to be selected.
3.3 TESTING DIODE/CONTINUITY
3.3.1 Connect the black test lead to the COM jack
and the red test lead to the V/ jack. ( NOTE: The
polarity of red lead connection is positive“ ”)
3.3.2 Set the rotary switch at
position and
connect the red lead to the anode, the black lead
to the cathode of the diode under testing. The
meter will show the approx. Forward voltage drop
of the diode. If the lead connection is reversed,
only figure“1”will be displayed. If continuity exists
( i.e., resistance less than about 70 ), built in
buzzer will sound.

3.4 MEASURING RESISTANCE
3.4.1 Connect the black test lead to the COM jack
and the red test lead to the V/ jack. ( NOTE :The
polarity of red lead connection is positive“”)
3.4.2 Set the rotary switch at desired range
position and connect test leads across the
resistance under measurement. Read LCD
display.
NOTE:
1. For resistance above 1M, the meter may take
a few seconds to stabilize reading.
2. When the input is not connected, i.e. at open
circuit, the figure “1”will be displayed for the
overrange condition.
3. When checking in - circuit resistance, be sure
the circuit under test has all power removed and all
capacitors are full discharged.
4. At 200M range display is 10 counts when test
leads are shorted. These counts have to be
subtracted from measuring results. For example,
when measuring 100M resistance, the reading
will be 101.0 and the correct measuring result
should be 101.0 1.0 = 100.0 M.
