PC INTERFACE AUTO-RANGE DIGITAL MULTIMETER
3. Connect test leads in series with the load in which the current is to
be measured.
4. Read LCD display, The polarity of red lead connection will be
indicated when making a DC measurement.
MEASURING RESISTANCE
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack ( ). 
2. Set the function switch to

3. Make sure all the power of the circuit to be measured is off.
4. Connect the test leads to the circuit to be measured. The range
will change automatically, and will hold on the range that will display
the measured resistance with the best resolution.
5. The value indicated on the display is the measured value of
resistance with proper decimal point and annunciation indication.
DIODE TEST
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (Diode).
2. Set the function switch to diode/continuity
3. Make sure all the power is off.
4. To select diode test, touch the mode selection switch (diode/
continuity) and the "diode" mark is indicated in the left side on the
display. This is diode check mode.
When you touch the switch again, the mode changes to the
continuity test mode.
5. Next, connect the test leads to the diode be tested. When
measuring the forward voltage across diode a normal diode will
indicate 0.4V to 0.7V and the reverse voltage will indicate "OL"
(same as on open condition).
For a short-circuited diode, a value near 0 mV will be displayed.

CONTINUITY CHECK
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack ( ).

2. Set the function switch to diode/continuity.
3.To select continuity test, touch the mode selection switch
(diode/buzzer) and the "·)))" mark is indicated in the left side on the
display. This is continuity check mode. In the continuity mode, a
buzzer sounds when the resistance of the circuit to be measured is
less than approx.30 .

MEASURING CAPACITANCE
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (CAP). (NOTE: The polarity of the lead connection is
positive "+")
2. Connect test leads across the capacitor under measurement and
be sure that the polarity of connection is observed.
NOTE:
1. When checking in-circuit capacitance, be sure that the circuit has
all power removed and all capacitor are fully discharged
2. The range control mode in capacitance measurement is auto-
ranging.
MEASURING FREQUENCY
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (Hz).
2. Set the function switch to "Hz/% duty" range.
3. Connect the test leads to the circuit to be measured. The range
will change that will display the measured frequency with the best
resolution.
When you push the "HZ/%" button, the mode changes to the duty
cycle check mode.
